with the greatest refinement of design and execution, and the aid of
sculpture, both in relief and in the round, was invoked to give splendor
and significance to the monument. The statue of the deity was the focus
of internal interest, while externally, groups of statues representing
the Olympian deities or the mythical exploits of gods, demigods, and
heroes, adorned the gables. Relief carvings in the friezes and metopes
commemorated the favorite national myths. In these sculptures we have
the finest known adaptations of pure sculpture--_i.e._, sculpture
treated as such and complete in itself--to an architectural framework.
The noblest examples of this decorative sculpture are those of the
Parthenon, consisting of figures in the full round from the pediments,
groups in high relief from the metopes, and the beautiful frieze of the
Panathenaic procession from the cella-wall under the pteroma ceiling.
The greater part of these splendid works are now in the British Museum,
whither they were removed by Lord Elgin in 1801. From Olympia, Ægina,
and Phigaleia, other master-works of the same kind have been transferred
to the museums of Europe. In the Doric style there was little carving
other than the sculpture, the ornament being mainly polychromatic. Greek
Ionic and Corinthian monuments, however, as well as minor works such as
steles, altars, etc., were richly adorned with carved mouldings and
friezes, festoons, acroteria, and other embellishments executed with the
chisel. The anthemion ornament, a form related to the Egyptian lotus and
Assyrian palmette, most frequently figures in these. It was made into
designs of wonderful vigor and beauty (Fig. 32).
+DETAIL AND EXECUTION.+ In the handling and cutting of stone the Greeks
displayed a surpassing skill and delicacy. While ordinarily they were
content to use stones of moderate size, they never hesitated at any
dimension necessary for proper effect or solid construction. The lower
drums of the Parthenon peristyle are 6 feet 6½ inches in diameter, and
2 feet 10 inches high, cut from single blocks of Pentelic marble. The
architraves of the Propylæa at Athens are each made up of two lintels
placed side by side, the longest 17 feet 7 inches long, 3 feet 10 inches
high, and 2 feet 4 inches thick. In the colossal temples of Asia Minor,
where the taste for the vast and grandiose was more pronounced, blocks
of much greater size were used. These enormous stones were cut and
fitted with the most scrupulous exactness. The walls of all important
structures were built in regular courses throughout, every stone
carefully bedded with extremely close joints. The masonry was usually
laid up without cement and clamped with metal; there is no filling in
with rubble and concrete between mere facings of cut stone, as in most
modern work. When the only available stone was of coarse texture it was
finished with a coating of fine stucco, in which sharp edges and minute
detail could be worked.
The details were, in the best period, executed with the most
extraordinary refinement and care. The profiles of capitals and
mouldings, the carved ornament, the arrises of the flutings, were cut
with marvellous precision and delicacy. It has been rightly said that
the Greeks “built like Titans and finished like jewellers.” But this
perfect finish was never petty nor wasted on unworthy or vulgar design.
The just relation of scale between the building and all its parts was
admirably maintained; the ornament was distributed with rare judgment,
and the vigor of its design saved it from all appearance of triviality.
The sensitive taste of the Greeks led them into other refinements than
those of mere mechanical perfection. In the Parthenon especially, but
also in lesser degree in other temples, the seemingly straight lines of
the building were all slightly curved, and the vertical faces inclined.
This was done to correct the monotony and stiffness of absolutely
straight lines and right angles, and certain optical illusions which
their acute observation had detected. The long horizontal lines of the
stylobate and cornice were made convex upward; a similar convexity in
the horizontal corona of the pediment counteracted the seeming concavity
otherwise resulting from its meeting with the multiplied inclined lines
of the raking cornice. The columns were almost imperceptibly inclined
toward the cella, and the corner intercolumniations made a trifle
narrower than the rest; while the vertical lines of the arrises of the
flutings were made convex outward with a curve of the utmost beauty and
delicacy. By these and other like refinements there was imparted to the
monument an elasticity and vigor of aspect, an elusive and surprising
beauty impossible to describe and not to be explained by the mere
composition and general proportions, yet manifest to every cultivated
eye.[10]
[Footnote 10: These refinements, first noticed by Allason in
1814, and later confirmed by Cockerell and Haller as to the
columns, were published to the world in 1838 by Hoffer, verified
by Penrose in 1846, and further developed by the investigations
of Ziller and later observers.]

+HISTORIC DEVELOPMENT.+ The history of Greek architecture, subsequent to
the Heroic or Primitive Age, may be divided into periods as follows:
The ARCHAIC; from 650 to 500 B.C.
The TRANSITIONAL; from 500 to 460 B.C., or to the revival of prosperity
after the Persian wars.
The PERICLEAN; from 460 to 400 B.C.
The FLORID or ALEXANDRIAN; from 400 to 300 B.C.
The DECADENT; 300 to 100 B.C.
The ROMAN; 100 B.C. to 200 A.D.
These dates are, of course, somewhat arbitrary; it is impossible to set
exact bounds to style-periods, which must inevitably overlap at certain
points, but the dates, as given above, will assist in distinguishing the
successive phases of the history.
+ARCHAIC PERIOD.+ The archaic period is characterized by the exclusive
use of the Doric order, which appears in the earliest monuments complete
in all its parts, but heavy in its proportions and coarse in its
execution. The oldest known temples of this period are the +Apollo
Temple+ at Corinth (650 B.C.?), and the +Northern Temple+ on the
acropolis at +Selinus+ in Sicily (cir. 610-590 B.C.). They are both of a
coarse limestone covered with stucco. The columns are low and massive
(4⅓ to 4⅔ diameters in height), widely spaced, and carry a very high
entablature. The triglyphs still appear around the cella wall under the
pteroma ceiling, an illogical detail destined to disappear in later
buildings. Other temples at Selinus date from the middle or latter part
of the sixth century; they have higher columns and finer profiles than
those just mentioned. The great +Temple of Zeus+ at +Selinus+ was the
earliest of five colossal Greek temples of very nearly identical
dimensions; it measured 360 feet by 167 feet in plan, but was never
completed. During the second half of the sixth century important Doric
temples were built at Pæstum in South Italy, and Agrigentum in Sicily;
the somewhat primitive temple at Assos in Asia Minor, with uncouth
carvings of centaurs and monsters on its architrave, belongs to this
same period. The +Temple of Zeus+ at +Agrigentum+ (Fig. 33) is another
singular and exceptional design, and was the second of the five colossal
temples mentioned above. The pteroma was entirely enclosed by walls with
engaged columns showing externally, and was of extraordinary width. The
walls of the narrow cella were interrupted by heavy piers supporting
atlantes, or applied statues under the ceiling. There seem to have been
windows between these figures, but it is not clear whence they borrowed
their light, unless it was admitted by the omission of the metopes
between the external triglyphs.
[Illustration: FIG. 33.--TEMPLE OF ZEUS. AGRIGENTUM.]
+THE TRANSITION.+ During the transitional period there was a marked
improvement in the proportions, detail, and workmanship of the temples.
The cella was made broader, the columns more slender, the entablature
lighter. The triglyphs disappeared from the cella wall, and sculpture of
a higher order enhanced the architectural effect. The profiles of the
mouldings and especially of the capitals became more subtle and refined
in their curves, while the development of the Ionic order in important
monuments in Asia Minor was preparing the way for the splendors of the
Periclean age. Three temples especially deserve notice: the +Athena
Temple+ on the island of +Ægina+, the +Temple of Zeus+ at +Olympia+, and
the so-called +Theseum+--perhaps a temple of Heracles--in Athens. They
belong to the period 470-450 B.C.; they are all hexastyle and
peripteral, and without triglyphs on the cella wall. Of the three the
second in the list is interesting as the scene of those rites which
preceded and accompanied the Panhellenic Olympian games, and as the
central feature of the Altis, the most complete temple-group and
enclosure among all Greek remains. It was built of a coarse
conglomerate, finished with fine stucco, and embellished with sculpture
by the greatest masters of the time. The adjacent +Heraion+ (temple of
Hera) was a highly venerated and ancient shrine, originally built with
wooden columns which, according to Pausanias, were replaced one by one,
as they decayed, by stone columns. The truth of this statement is
attested by the discovery of a singular variety of capitals among its
ruins, corresponding to the various periods at which they were added.
The Theseum is the most perfectly preserved of all Greek temples, and in
the refinement of its forms is only surpassed by those of the Periclean
age.
[Illustration: FIG. 34.--RUINS OF THE PARTHENON.]
[Illustration: FIG. 35.--PLAN OF ERECHTHEUM.]
[Illustration: FIG. 36.--WEST END OF ERECHTHEUM, RESTORED.]
+THE PERICLEAN AGE.+ The Persian wars may be taken as the dividing line
between the Transition period and the Periclean age. The _élan_ of
national enthusiasm that followed the expulsion of the invader, and the
glory and wealth which accrued to Athens as the champion of all Hellas,
resulted in a splendid reconstruction of the Attic monuments as well as
a revival of building activity in Asia Minor. By the wise administration
of Pericles and by the genius of Ictinus, Phidias, and other artists of
surpassing skill, the Acropolis at Athens was crowned with a group of
buildings and statues absolutely unrivalled. Chief among them was the
+Parthenon+, the shrine of Athena Parthenos, which the critics of all
schools have agreed in considering the most faultless in design and
execution of all buildings erected by man (Figs. 31, 34, and
Frontispiece). It was an octastyle peripteral temple, with seventeen
columns on the side, and measured 220 by 100 feet on the top of the
stylobate. It was the work of Ictinus and Callicrates, built to enshrine
the noble statue of the goddess by Phidias, a standing chryselephantine
figure forty feet high. It was the masterpiece of Greek architecture not
only by reason of its refinements of detail, but also on account of the
beauty of its sculptural adornments. The frieze about the cella wall
under the pteroma ceiling, representing in low relief with masterly
skill the Panathenaic procession; the sculptured groups in the metopes,
and the superb assemblages of Olympic and symbolic figures of colossal
size in the pediments, added their majesty to the perfection of the
architecture. Here also the horizontal curvatures and other refinements
are found in their highest development. Northward from it, upon the
Acropolis, stood the +Erechtheum+, an excellent example of the
Attic-Ionic style (Figs. 35, 36). Its singular irregularities of plan
and level, and the variety of its detail, exhibit in a striking way the
Greek indifference to mere formal symmetry when confronted by practical
considerations. The motive in this case was the desire to include in one
design several existing and venerated shrines to Attic deities and
heroes--Athena Polias, Poseidon, Pandrosus, Erechtheus, Boutes, etc.
Begun by unknown architects in 479 B.C., and not completed until 408
B.C., it remains in its ruin still one of the most interesting and
attractive of ancient buildings. Its two colonnades of differing design,
its beautiful north doorway, and the unique and noble caryatid porch or
balcony on the south side are unsurpassed in delicate beauty combined
with vigor of design.[11] A smaller monument of the Ionic order, the
amphiprostyle temple to +Nike Apteros+--the Wingless Victory--stands on
a projecting spur of the Acropolis to the southwest. It measures only 27
feet by 18 feet in plan; the cella is nearly square; the columns are
sturdier than those of the Erechtheum, and the execution of the monument
is admirable. It was the first completed of the extant buildings of the
group of the Acropolis and dates from 466 B.C.
[Footnote 11: See Appendix, p. 427.]
[Illustration: FIG. 37.--PROPYLÆA AT ATHENS. PLAN.]
In the +Propylæa+ (Fig. 37), the monumental gateway to the Acropolis,
the Doric and Ionic orders appear to have been combined for the first
time (437 to 432 B.C.). It was the master work of Mnesicles. The front
and rear façades were Doric hexastyles; adjoining the front porch were
two projecting lateral wings employing a smaller Doric order. The
central passageway led between two rows of Ionic columns to the rear
porch, entered by five doorways and crowned, like the front, with a
pediment. The whole was executed with the same splendor and perfection
as the other buildings of the Acropolis, and was a worthy gateway to the
group of noble monuments which crowned that citadel of the Attic
capital. The two orders were also combined in the temple of +Apollo
Epicurius+ at +Phigalæa+ (Bassæ). This temple was erected in 430 B.C. by
Ictinus, who used the Ionic order internally to decorate a row of
projecting piers instead of free-standing columns in the naos, in which
there was also a single Corinthian column of rather archaic design,
which may have been used as a support for a statue or votive offering.
+ALEXANDRIAN AGE.+ A period of reaction followed the splendid
architectural activity of the Periclean age. A succession of disastrous
wars--the Sicilian, Peloponnesian, and Corinthian--drained the energies
and destroyed the peace of European Greece for seventy-five years,
robbing Athens of her supremacy and inflicting wounds from which she
never recovered. In the latter part of the fourth century, however, the
triumph of the Macedonian empire over all the Mediterranean lands
inaugurated a new era of architectural magnificence, especially in Asia
Minor. The keynote of the art of this time was splendor, as that of the
preceding age was artistic perfection. The Corinthian order came into
use, as though the Ionic were not rich enough for the sumptuous taste of
the time, and capitals and bases of novel and elaborate design
embellished the Ionic temples of Asia Minor. In the temple of +Apollo
Didymæus+ at Miletus, the plinths of the bases were made octagonal and
panelled with rich scroll-carvings; and the piers which buttressed the
interior faces of the cella-walls were given capitals of singular but
elegant form, midway between the Ionic and Corinthian types. This temple
belongs to the list of colossal edifices already referred to; its
dimensions were 366 by 163 feet, making it the largest of them all. The
famous +Artemisium+ (temple of Artemis or Diana) measured 342 by 163
feet. Several of the columns of the latter were enriched with sculptured
figures encircling the lower drums of the colossal shafts. The most
lavish expenditure was bestowed upon small structures, shrines, and
sarcophagi. The graceful monument still visible in Athens, erected by
the choragus Lysicrates in token of his victory in the choral
competitions, belongs to this period (330 B.C.). It is circular, with a
slightly domical imbricated roof, and is decorated with elegant engaged
Corinthian columns (Fig. 38). In the Imperial Museum at Constantinople
are several sarcophagi of this period found at Sidon, but executed by
Greek artists, and of exceptional beauty. They are in the form of
temples or shrines; the finest of them, supposed by some to have been
made for Alexander’s favorite general Perdiccas, and by others for the
Persian satrap who figures prominently on its sculptured reliefs, is the
most sumptuous work of the kind in existence. The exquisite polychromy
of its beautiful reliefs and the perfection of its rich details of
cornice, pediment, tiling, and crestings, make it an exceedingly
interesting and instructive example of the minor architecture of the
period.
[Illustration: FIG. 38.--CHORAGIC MONUMENT OF LYSICRATES.
(Restored model, N.Y.)]
+THE DECADENCE.+ After the decline of Alexandrian magnificence Greek art
never recovered its ancient glory, but the flame was not suddenly
extinguished. While in Greece proper the works of the second and third
centuries B.C., are for the most part weak and lifeless, like the +Stoa
of Attalus+ (175 B.C.) and the +Tower of the Winds+ (the Clepsydra of
Andronicus Cyrrhestes, 100 B.C.) at Athens or the Portico of Philip in
Delos, there were still a few worthy works built in Asia Minor. The
splendid +Altar+ erected at +Pergamon+ by Eumenes II. (circ. 180 B.C.)
in the Ionic order, combined sculpture of extraordinary vigor with
imposing architecture in masterly fashion. At +Aizanoi+ an Ionic +Temple
to Zeus+, by some attributed to the Roman period, but showing rather the
character of good late Greek work, deserves mention for its elegant
details, and especially for its frieze-decoration of acanthus leaves and
scrolls resembling those of a Corinthian capital.
[Illustration: FIG. 39.--TEMPLE OF OLYMPIAN ZEUS. ATHENS.]
+ROMAN PERIOD.+ During this period, _i.e._, throughout the second and
first centuries B.C., the Roman dominion was spreading over Greek
territory, and the structures erected subsequent to the conquest partake
of the Roman character and mingle Roman conceptions with Greek details
and _vice versâ_. The temple of the +Olympian Zeus+ at Athens (Fig. 39),
a mighty dipteral Corinthian edifice measuring 354 by 171 feet, standing
on a vast terrace or temenos surrounded by a buttressed wall, was begun
by Antiochus Epiphanes (170 B.C.) on the site of an earlier unfinished
Doric temple of the time of Pisistratus, and carried out under the
direction of the Roman architect, Cossutius. It was not, however,
finally completed until the time of Hadrian, 130 A.D. Meanwhile Sulla
had despoiled it of several columns[12] which he carried to Rome (86
B.C.), to use in the rebuilding of the temple of Jupiter on the Capitol,
where they undoubtedly served as models in the development of the Roman
Corinthian order. The columns were 57 feet high, with capitals of the
most perfect Corinthian type; fifteen are now standing, and one lies
prostrate near by. To the Roman period also belong the +Agora Gate+
(circ. 35 B.C.), the +Arch of Hadrian+ (117 A.D.), the +Odeon of
Regilla+ or of Herodes Atticus (143 A.D.), at Athens, and many temples
and tombs, theatres, arches, etc., in the Greek provinces.
[Footnote 12: L. Bevier, in _Papers of the American Classical
School at Athens_ (vol. i., pp. 195, 196), contends that these
were columns left from the old Doric temple. This is untenable,
for Sulla would certainly not have taken the trouble to carry
away archaic Doric columns, with such splendid Corinthian columns
before him.]
+SECULAR MONUMENTS; PROPYLÆA.+ The stately gateway by which the
Acropolis was entered has already been described. It was the noblest and
most perfect of a class of buildings whose prototype is found in the
monumental columnar porches of the palace-group at Persepolis. The
Greeks never used the arch in these structures, nor did they attach to
them the same importance as did most of the other nations of antiquity.
The Altis of Olympia, the national shrine of Hellenism, appears to have
had no central gateway of imposing size, but a number of insignificant
entrances disposed at random. The +Propylæa+ of +Sunium+, +Priene+ and
+Eleusis+ are the most conspicuous, after those of the Athenian
Acropolis. Of these the Ionic gateway at Priene is the finest, although
the later of the two at Eleusis is interesting for its anta-capitals.
(_Anta_ = a flat pilaster decorating the end of a wing-wall and treated
with a base and capital usually differing from those of the adjacent
columns.) These are of Corinthian type, adorned with winged horses,
scrolls, and anthemions of an exuberant richness of design,
characteristic of this late period.
+COLONNADES, STOÆ.+ These were built to connect public monuments (as the
Dionysiac theatre and Odeon at Athens); or along the sides of great
public squares, as at Assos and Olympia (the so-called +Echo Hall+); or
as independent open public halls, as the +Stoa Diple+ at Thoricus. They
afforded shelter from sun and rain, places for promenading, meetings
with friends, public gatherings, and similar purposes. They were rarely
of great size, and most of them are of rather late date, though the
archaic structure at Pæstum, known as the +Basilica+, was probably in
reality an open hall of this kind.
[Illustration: FIG. 40.--PLAN OF GREEK THEATRE.
o, _Orchestra_; l, _Logeion_; p, _Paraskenai_; _s, s_, _Stoa_.]
+THEATRES, ODEONS.+ These were invariably cut out of the rocky
hillsides, though in a few cases (Mantinæa, Myra, Antiphellus) a part of
the seats were sustained by a built-up substructure and walls to eke out
the deficiency of the hill-slope under them. The front of the excavation
was enclosed by a stage and a set scene or background, built up so as to
leave somewhat over a semicircle for the _orchestra_ or space enclosed
by the lower tier of seats (Fig. 40). An altar to Dionysus (Bacchus) was
the essential feature in the foreground of the orchestra, where the
Dionysiac choral dance was performed. The seats formed successive steps
of stone or marble sweeping around the sloping excavation, with carved
marble thrones for the priests, archons, and other dignitaries. The only
architectural decoration of the theatre was that of the set scene or
_skene_, which with its wing-walls (_paraskenai_) enclosing the stage
(_logeion_) was a permanent structure of stone or marble adorned with
doors, cornices, pilasters, etc. This has perished in nearly every case;
but at Aspendus, in Asia Minor, there is one still fairly well
preserved, with a rich architectural decoration on its inner face. The
extreme diameter of the theatres varied greatly; thus at Aizanoi it is
187 feet, and at Syracuse 495 feet. The theatre of Dionysus at Athens
(finished 325 B.C.) could accommodate thirty thousand spectators.
The odeon differed from the theatre principally in being smaller and
entirely covered in by a wooden roof. The +Odeon of Regilla+, built by
Herodes Atticus in Athens (143 A.D.), is a well-preserved specimen of
this class, but all traces of its cedar ceiling and of its intermediate
supports have disappeared.
+BUILDINGS FOR ATHLETIC CONTESTS.+ These comprised stadia and
hippodromes for races, and gymnasia and palæstræ for individual
exercise, bathing, and amusement. The _stadia_ and _hippodromes_ were
oblong enclosures surrounded by tiers of seats and without conspicuous
architectural features. The _palæstra_ or _gymnasium_--for the terms are
not clearly distinguished--was a combination of courts, chambers, tanks
(_piscinæ_) for bathers and _exedræ_ or semicircular recesses provided
with tiers of seats for spectators and auditors, destined not merely for
the exercises of athletes preparing for the stadium, but also for the
instruction and diversion of the public by recitations, lectures, and
discussions. It was the prototype of the Roman thermæ, but less
imposing, more simple in plan and adornment. Every Greek city had one or
more of them, but they have almost wholly disappeared, and the brief
description by Vitruvius and scanty remains at Alexandria Troas and
Ephesus furnish almost the only information we possess regarding their
form and arrangement.
+TOMBS.+ These are not numerous, and the most important are found in
Asia Minor. The greatest of these is the famed +Mausoleum+ at
Halicarnassus in Caria, the monument erected to the king Mausolus by his
widow Artemisia (354 B.C.; Fig. 41). It was designed by Satyrus and
Pythius in the Ionic style, and comprised a podium or base 50 feet high
and measuring 80 feet by 100 feet, in which was the sepulchre. Upon this
base stood a cella surrounded by thirty-six Ionic columns; and crowned
by a pyramidal roof, on the peak of which was a colossal marble quadriga
at a height of 130 feet. It was superbly decorated by Scopas and other
great sculptors with statues, marble lions, and a magnificent frieze.
The British Museum possesses fragments of this most imposing monument.
At Xanthus the +Nereid Monument+, so called from its sculptured figures
of Nereides, was a somewhat similar design on a smaller scale, with
sixteen Ionic columns. At Mylassa was another tomb with an open
Corinthian colonnade supporting a roof formed in a stepped pyramid. Some
of the later rock-cut tombs of Lycia at Myra and Antiphellus may also be
counted as Hellenic works.
[Illustration: FIG. 41.--MAUSOLEUM AT HALICARNASSUS.
(As restored by the author.)]
+DOMESTIC ARCHITECTURE.+ This never attained great importance in Greece,
and our knowledge of the typical Greek house is principally derived from
literary sources. Very few remains of Greek houses have been found
sufficiently well preserved to permit of restoring even the plan. It is
probable that they resembled in general arrangement the houses of
Pompeii (see p. 107); but that they were generally insignificant in size
and decoration. The exterior walls were pierced only by the entrance
doors, all light being derived from one or more interior courts. In the
Macedonian epoch there must have been greater display and luxury in
domestic architecture, but no remains have come down to us of sufficient
importance or completeness to warrant further discussion.
+MONUMENTS.+ In addition to those already mentioned in the text
the following should be enumerated:
PREHISTORIC PERIOD. In the Islands about Santorin, remains of
houses antedating 1500 B.C.; at Tiryns the Acropolis, walls, and
miscellaneous ruins; the like also at Mycenæ, besides various
tombs; walls and gates at Samos, Thoricus, Menidi, Athens, etc.
ARCHAIC PERIOD. Doric Temples at Metapontium (by Durm assigned to
610 B.C.), Selinus, Agrigentum, Pæstum; at Athens the first
Parthenon; in Asia Minor the primitive Ionic Artemisium at Ephesus
and the Heraion at Samos, the latter the oldest of colossal Greek
temples.
TRANSITIONAL PERIOD. At Agrigentum, temples of Concord, Castor and
Pollux, Demeter, Æsculapius, all circ. 480 B.C.; temples at
Selinus and Segesta.
PERICLEAN PERIOD. In Athens the Ionic temple on the Illissus,
destroyed during the present century; on Cape Sunium the temple of
Athena, 430 B.C., partly standing; at Nemea, the temple of Zeus;
at Tegea, the temple of Athena Elea (400? B.C.); at Rhamnus, the
temples of Themis and of Nemesis; at Argos, two temples, stoa, and
other buildings; all these were Doric.
ALEXANDRIAN PERIOD. The temple of Dionysus at Teos; temple of
Artemis Leucophryne at Magnesia, both about 330 B.C. and of the
Ionic order.
DECADENCE AND ROMAN PERIOD. At Athens the Stoa of Eumenes, circ.
170 B.C.; the monument of Philopappus on the Museum hill, 110
A.D.; the Gymnasium of Hadrian, 114 to 137 A.D.; the last two of
the Corinthian order.
THEATRES. Besides those already mentioned there are important
remains of theatres at Epidaurus, Argos, Segesta, Iassus (400?
B.C.), Delos, Sicyon, and Thoricus; at Aizanoi, Myra, Telmissus,
and Patara, besides many others of less importance scattered
through the Hellenic world. At Taormina are extensive ruins of a
large Greek theatre rebuilt in the Roman period.

+LAND AND PEOPLE.+ The geographical position of Italy conferred upon her
special and obvious advantages for taking up and carrying northward and
westward the arts of civilization. A scarcity of good harbors was the
only drawback amid the blessings of a glorious climate, fertile soil,
varied scenery, and rich material resources. From a remote antiquity
Dorian colonists had occupied the southern portion and the island of
Sicily, enriching them with splendid monuments of Doric art; and
Phœnician commerce had brought thither the products of Oriental art and
industry. The foundation of Rome in 753 B.C. established the nucleus
about which the sundry populations of Italy were to crystallize into the
Roman nation, under the dominating influence of the Latin element. Later
on, the absorption of the conquered Etruscans added to this composite
people a race of builders and engineers, as yet rude and uncouth in
their art, but destined to become a powerful factor in developing the
new architecture that was to spring from the contact of the practical
Romans with the noble art of the Greek centres.
+GENERAL CHARACTERISTICS.+ While the Greeks bequeathed to posterity the
most perfect models of form in literary and plastic art, it was reserved
for the Romans to work out the applications of these to every-day
material life. The Romans were above all things a practical people.
Their consummate skill as organizers is manifest in the marvellous
administrative institutions of their government, under which they united
the most distant and diverse nationalities. Seemingly deficient in
culture, they were yet able to recast the forms of Greek architecture in
new moulds, and to evolve therefrom a mighty architecture adapted to
wholly novel conditions. They brought engineering into the service of
architecture, which they fitted to the varied requirements of
government, public amusement, private luxury, and the common comfort.
They covered the antique world with arches and amphitheatres, with
villas, baths, basilicas, and temples, all bearing the unmistakable
impress of Rome, though wrought by artists and artisans of divers races.
Only an extraordinary genius for organization could have accomplished
such results.
The architects of Rome marvellously extended the range of their art, and
gave it a flexibility by which it accommodated itself to the widest
variety of materials and conditions. They made the arch and vault the
basis of their system of design, employing them on a scale previously
undreamed of, and in combinations of surpassing richness and majesty.
They systematized their methods of construction so that soldiers and
barbarians could execute the rough mass of their buildings, and
formulated the designing of the decorative details so that artisans of
moderate skill could execute them with good effect. They carried the
principle of repetition of motives to its utmost limit, and sought to
counteract any resulting monotony by the scale and splendor of the
design. Above all they developed planning into a fine art, displaying
their genius in a wonderful variety of combinations and in an unfailing
sense of the demands of constructive propriety, practical convenience,
and artistic effect. Where Egyptian or Greek architecture shows one type
of plan, the Roman shows a score.
+GREEK INFLUENCE.+ Previous to the closing years of the Republic the
Romans had no art but the Etruscan. The few buildings of importance they
possessed were of Etruscan design and workmanship, excepting a small
number built by Greek hands. It was not until the Empire that Roman
architecture took on a truly national form. True Roman architecture is
essentially imperial. The change from the primitive Etruscan style to
the splendors of the imperial age was due to the conquest of the Greek
states. Not only did the Greek campaigns enrich Rome with an
unprecedented wealth of artistic spoils; they also brought into Italy
hosts of Greek artists, and filled the minds of the campaigners with the
ambition to realize in their own dominions the marble colonnades, the
temples, theatres, and propylæa of the Greek cities they had pillaged.
The Greek orders were adopted, altered, and applied to arcaded designs
as well as to peristyles and other open colonnades. The marriage of the
column and arch gave birth to a system of forms as characteristic of
Roman architecture as the Doric or Ionic colonnade is of the Greek.
+THE ROMAN ORDERS.+ To meet the demands of Roman taste the Etruscan
column was retained with its simple entablature; the Doric and Ionic
were adopted in a modified form; the Corinthian was developed into a
complete and independent order, and the Composite was added to the list.
A regular system of proportions for all these five orders was gradually
evolved, and the mouldings were profiled with arcs of circles instead of
the subtler Greek curves. In the building of many-storied structures the
orders were superposed, the more slender over the sturdier, in an
orderly and graded succession. The immense extent and number of the
Roman buildings, the coarse materials often used, the relative scarcity
of highly trained artisans, and above all, the necessity of making a
given amount of artistic design serve for the largest possible amount of
architecture, combined to direct the designing of detail into uniform
channels. Thus in time was established a sort of canon of proportions,
which was reduced to rules by Vitruvius, and revived in much more
detailed and precise form by Vignola in the sixteenth century.
[Illustration: FIG. 42.--ROMAN DORIC ORDER.
(THEATRE OF MARCELLUS).]
In each of the orders, including the Doric, the column was given a base
one half of a diameter in height (the unit of measurement being the
diameter of the lower part of the shaft, the _crassitudo_ of Vitruvius).
The shaft was made to contract about one-sixth in diameter toward the
capital, under which it was terminated by an _astragal_ or collar of
small mouldings; at the base it ended in a slight flare and fillet
called the _cincture_. The entablature was in all cases given not far
from one quarter the height of the whole column. The +Tuscan+ order was
a rudimentary or Etruscan Doric with a column seven diameters high and a
simple entablature without triglyphs, mutules, or dentils. But few
examples of its use are known. The +Doric+ (Fig. 42) retained the
triglyphs and metopes, the mutules and guttæ of the Greek; but the
column was made eight diameters high, the shaft was smooth or had deep
flutings separated by narrow fillets, and was usually provided with a
simple moulded base on a square plinth. Mutules were used only over the
triglyphs, and were even replaced in some cases by dentils; the corona
was made lighter than the Greek, and a cymatium replaced the antefixæ on
the lateral cornices. The Ionic underwent fewer changes, and these
principally in the smaller mouldings and details of the capital. The
column was nine diameters high (Fig. 43). The +Corinthian+ was made into
an independent order by the designing of a special base of small _tori_
and _scotiæ_, and by sumptuously carved _modillions_ or brackets
enriching the cornice and supporting the corona above a denticulated
bed-mould (Fig. 44). Though the first designers of the modillion were
probably Greeks, it must, nevertheless, be taken as really a Roman
device, worthily completing the essentially Roman Corinthian order. The
+Composite+ was formed by combining into one capital portions of the
Ionic and Corinthian, and giving to it a simplified form of the
Corinthian cornice. The Corinthian order remained, however, the favorite
order of Roman architecture.
[Illustration: FIG. 43.--ROMAN IONIC ORDER.]
+USE OF THE ORDERS.+ The Romans introduced many innovations in the
general use and treatment of the orders. Monolithic shafts were
preferred to those built up of superposed drums. The fluting was omitted
on these, and when hard and semi-precious stone like porphyry or
verd-antique was the material, it was highly polished to bring out its
color. These polished monoliths were often of great size, and they were
used in almost incredible numbers.
[Illustration: FIG. 44.--CORINTHIAN ORDER
(TEMPLE OF CASTOR AND POLLUX).]
Another radical departure from Greek usage was the mounting of columns
on pedestals to secure greater height without increasing the size of the
column and its entablature. The Greek _anta_ was developed into the
Roman pilaster or flattened wall-column, and every free column, or range
of columns perpendicular to the façade, had its corresponding pilaster
to support the wall-end of the architrave. But the most radical
innovation was the general use of engaged columns as wall-decorations or
buttresses. The engaged column projected from the wall by more than half
its diameter, and was built up with the wall as a part of its substance
(Fig. 45). The entablature was in many cases advanced only over the
columns, between which it was set back almost to the plane of the wall.
This practice is open to the obvious criticism that it makes the column
appear superfluous by depriving it of its function of supporting the
continuous entablature. The objection has less weight when the
projecting entablature over the column serves as a pedestal for a statue
or similar object, which restores to the column its function as a
support (see the Arch of Constantine, Fig. 63).
[Illustration: FIG. 45.--ROMAN ARCADE WITH ENGAGED COLUMNS
(From the Colosseum.)]
+ARCADES.+ The orders, though probably at first used only as free
supports in porticos and colonnades, were early applied as decorations
to arcaded structures. This practice became general with the
multiplication of many-storied arcades like those of the amphitheatres,
the engaged columns being set between the arches as buttresses,
supporting entablatures which marked the divisions into stories (Fig.
45). This combination has been assailed as a false and illogical device,
but the criticism proceeds from a too narrow conception of architectural
propriety. It is defensible upon both artistic and logical grounds; for
it not only furnishes a most desirable play of light and shade and a
pleasing contrast of rectangular and curved lines, but by emphasizing
the constructive divisions and elements of the building and the vertical
support of the piers, it also contributes to the expressiveness and
vigor of the design.
+VAULTING.+ The Romans substituted vaulting in brick, concrete, or
masonry for wooden ceilings wherever possible, both in public and
private edifices. The Etruscans were the first vault-builders, and the
Cloaca Maxima, the great sewer of Republican Rome (about 500 B.C.) still
remains as a monument of their engineering skill. Probably not only
Etruscan engineers (whose traditions were perhaps derived from Asiatic
sources in the remote past), but Asiatic builders also from conquered
eastern provinces, were engaged together in the development of the
wonderful system of vaulted construction to which Roman architecture so
largely owed its grandeur. Three types of vault were commonly used: the
barrel-vault, the groined or four-part vault, and the dome.
[Illustration: FIG. 46.--BARREL VAULT.]
The barrel vault (Fig. 46) was generally semi-cylindrical in section,
and was used to cover corridors and oblong halls, like the
temple-cellas, or was bent around a curve, as in amphitheatre passages.
[Illustration: FIG. 47.--GROINED VAULT.
_g, g_, _Groins._]
The groined vault is formed by the intersection of two barrel-vaults
(Fig. 47). When several compartments of groined vaulting are placed
together over an oblong plan, a double advantage is secured. Lateral
windows can be carried up to the full height of the vaulting instead of
being stopped below its springing; and the weight and thrust of the
vaulting are concentrated upon a number of isolated points instead of
being exerted along the whole extent of the side walls, as with the
barrel-vault. The Romans saw that it was sufficient to dispose the
masonry at these points in masses at right angles to the length of the
hall, to best resist the lateral thrust of the vault. This appears
clearly in the plan of the Basilica of Constantine (Fig. 58).
The dome was in almost all Roman examples supported on a circular wall
built up from the ground, as in the Pantheon (Fig. 54). The pendentive
dome, sustained by four or eight arches over a square or octagonal plan,
is not found in true Roman buildings.
The Romans made of the vault something more than a mere constructive
device. It became in their hands an element of interior effect at least
equally important with the arch and column. No style of architecture has
ever evolved nobler forms of ceiling than the groined vault and the
dome. Moreover, the use of vaulting made possible effects of
unencumbered spaciousness and amplitude which could never be compassed
by any combination of piers and columns. It also assured to the Roman
monuments a duration and a freedom from danger of destruction by fire
impossible with any wooden-roofed architecture, however noble its form
or careful its execution.
+CONSTRUCTION.+ The constructive methods of the Romans varied with the
conditions and resources of different provinces, but were everywhere
dominated by the same practical spirit. Their vaulted architecture
demanded for the support of its enormous weights and for resistance to
its disruptive thrusts, piers and buttresses of great mass. To construct
these wholly of cut stone appeared preposterous and wasteful to the
Roman. Italy abounds in clay, lime, and a volcanic product, _pozzolana_
(from Puteoli or Pozzuoli, where it has always been obtained in large
quantities), which makes an admirable hydraulic cement. With these
materials it was possible to employ unskilled labor for the great bulk
of this massive masonry, and to erect with the greatest rapidity and in
the most economical manner those stupendous piles which, even in their
ruin, excite the admiration of every beholder.
[Illustration: FIG. 48.--ROMAN WALL MASONRY.
a, _Brickwork_; b, _Tufa ashlar_; r, _Opus reticulatum_;
i, _Opus incertum_.]
+STONE, CONCRETE, AND BRICK MASONRY.+ For buildings of an externally
decorative character such as temples, arches of triumph, and
amphitheatres, as well as in all places where brick and concrete were
not easily obtained, stone was employed. The walls were built by laying
up the inner and outer faces in _ashlar_ or cut stone, and filling in
the intermediate space with rubble (random masonry of uncut stone) laid
up in cement, or with concrete of broken stone and cement dumped into
the space in successive layers. The cement converted the whole into a
conglomerate closely united with the face-masonry. In Syria and Egypt
the local preference for stones of enormous size was gratified, and even
surpassed, as in Herod’s terrace-walls for the temple at Jerusalem
(p. 41), and in the splendid structures of Palmyra and Baalbec. In
Italy, however, stones of moderate size were preferred, and when blocks
of unusual dimensions occur, they are in many cases marked with false
joints, dividing them into apparently smaller blocks, lest they should
dwarf the building by their large scale. The general use in the Augustan
period of marble for a decorative lining or wainscot in interiors led in
time to the objectionable practice of coating buildings of concrete with
an apparel of sham marble masonry, by carving false joints upon an
external veneer of thin slabs of that material. Ordinary concrete walls
were frequently faced with small blocks of tufa, called, according to
the manner of its application, _opus reticulatum_, _opus incertum_,
_opus spicatum_, etc. (Fig. 48). In most cases, however, the facing was
of carefully executed brickwork, covered sometimes by a coating of
stucco. The bricks were large, measuring from one to two feet square
where used for quoins or arches, but triangular where they served only
as facings. Bricks were also used in the construction of skeleton ribs
for concrete vaults of large span.
+VAULTING.+ Here, as in the wall-masonry, economy and common sense
devised methods extremely simple for accomplishing vast designs. While
the smaller vaults were, so to speak, cast in concrete upon moulds made
of rough boards, the enormous weight of the larger vaults precluded
their being supported, while drying or “setting,” upon timber centrings
built up from the ground. Accordingly, a skeleton of light ribs was
first built on wooden centrings, and these ribs, when firmly “set,”
became themselves supports for intermediate centrings on which to cast
the concrete fillings between the ribs. The whole vault, once hardened,
formed really a monolithic curved lintel, exerting no thrust whatever,
so that the extraordinary precautions against lateral disruption
practised by the Romans were, in fact, in many cases quite superfluous.
+DECORATION.+ The temple of Castor and Pollux in the Forum (long
miscalled the temple of Jupiter Stator), is a typical example of Roman
architectural decoration, in which richness was preferred to the subtler
refinements of design (see Fig. 44). The splendid figure-sculpture which
adorned the Greek monuments would have been inappropriate on the
theatres and thermæ of Rome or the provinces, even had there been the
taste or the skill to produce it. Conventional carved ornament was
substituted in its place, and developed into a splendid system of highly
decorative forms. Two principal elements appear in this decoration--the
acanthus-leaf, as the basis of a whole series of wonderfully varied
motives; and symbolism, represented principally by what are technically
termed _grotesques_--incongruous combinations of natural forms, as when
an infant’s body terminates in a bunch of foliage (Fig. 49). Only to a
limited extent do we find true sculpture employed as decoration, and
that mainly for triumphal arches or memorial columns.
[Illustration: FIG. 49--ROMAN CARVED ORNAMENT.
(Lateran Museum.)]
The architectural mouldings were nearly always carved, the Greek
water-leaf and egg-and-dart forming the basis of most of the
enrichments; but these were greatly elaborated and treated with more
minute detail than the Greek prototypes. Friezes and bands were commonly
ornamented with the foliated scroll or _rinceau_ (a convenient French
term for which we have no equivalent). This motive was as characteristic
of Roman art as the anthemion was of the Greek. It consists of a
continuous stem throwing out alternately on either side branches which
curl into spirals and are richly adorned with rosettes, acanthus-leaves,
scrolls, tendrils, and blossoms. In the best examples the detail was
modelled with great care and minuteness, and the motive itself was
treated with extraordinary variety and fertility of invention. A derived
and enriched form of the anthemion was sometimes used for bands and
friezes; and grotesques, dolphins, griffins, infant genii, wreaths,
festoons, ribbons, eagles, and masks are also common features in Roman
relief carving.
[Illustration: FIG. 50.--ROMAN CEILING PANELS.
(a, From Palmyra; b, Basilica of Constantine.)]
The Romans made great use of panelling and of moulded plaster in their
interior decoration, especially for ceilings. The panelling of domes and
vaults was usually roughly shaped in their first construction and
finished afterward in stucco with rich moulding and rosettes. The panels
were not always square or rectangular, as in Greek ceilings, but of
various geometric forms in pleasing combinations (Fig. 50). In works of
a small scale the panels and decorations were wrought in relief in a
heavy coating of plaster applied to the finished structure, and these
stucco reliefs are among the most refined and charming products of Roman
art. (Baths of Titus; Baths at Pompeii; Palace of the Cæsars and tombs
at Rome.)
+COLOR DECORATION.+ Plaster was also used as a ground for painting,
executed in distemper or by the encaustic process, wax liquefied by a
hot iron being the medium for applying the color in the latter case.
Pompeii and Herculaneum furnish countless examples of brilliant
wall-painting in which strong primary colors form the ground, and a
semi-naturalistic, semi-fantastic representation of figures,
architecture and landscape is mingled with festoons, vines, and purely
conventional ornament. Mosaic was also employed to decorate floors and
wall-spaces, and sometimes for ceilings.[13] The later imperial baths
and palaces were especially rich in mosaic of the kind called opus
Grecanicum, executed with numberless minute cubes of stone or glass, as
in the Baths of Caracalla and the Villa of Hadrian at Tivoli.
[Footnote 13: See Van Dyke’s _History of Paintings_, p. 33.]
To the walls of monumental interiors, such as temples, basilicas, and
thermæ, splendor of color was given by veneering them with thin slabs of
rare and richly colored marble. No limit seems to have been placed upon
the costliness or amount of these precious materials. Byzantine
architecture borrowed from this practice its system of interior color
decoration.

+THE ETRUSCAN STYLE.+ Although the first Greek architects were employed
in Rome as early as 493 B.C., the architecture of the Republic was
practically Etruscan until nearly 100 B.C. Its monuments, consisting
mainly of city walls, tombs, and temples, are all marked by a general
uncouthness of detail, denoting a lack of artistic refinement, but they
display considerable constructive skill. In the Etruscan walls we meet
with both polygonal and regularly coursed masonry; in both kinds the
true arch appears as the almost universal form for gates and openings.
A famous example is the Augustan Gate at Perugia, a late work rebuilt
about 40 B.C., but thoroughly Etruscan in style. At Volaterræ (Volterra)
is another arched gate, and in Perugia fragments of still another appear
built into the modern walls.
The Etruscans built both structural and excavated tombs; they consisted
in general of a single chamber with a slightly arched or gabled roof,
supported in the larger tombs on heavy square piers. The interiors were
covered with pictures; externally there was little ornament except about
the gable and doorway. The latter had a stepped or moulded frame with
curious _crossettes_ or ears projecting laterally at the top. The gable
recalled the wooden roofs of Etruscan temples, but was coarse in detail,
especially in its mouldings. Sepulchral monuments of other types are
also met with, such as _cippi_ or memorial pillars, sometimes in groups
of five on a single pedestal (tomb at Albano).
Among the temples of Etruscan style that of +Jupiter Capitolinus+ on the
Capitol at Rome, destroyed by fire in 80 B.C., was the chief. Three
narrow chambers side by side formed a cella nearly square in plan,
preceded by a hexastyle porch of huge Doric, or rather Tuscan, columns
arranged in three aisles, widely spaced and carrying ponderous wooden
architraves. The roof was of wood; the cymatium and ornaments, as well
as the statues in the pediment, were of terra-cotta, painted and gilded.
The details in general showed acquaintance with Greek models, which
appeared in debased and awkward imitations of triglyphs, cornices,
antefixæ, etc.
[Illustration: FIG. 51.--TEMPLE FORTUNA VIRILIS. PLAN.]
+GREEK STYLE.+ The victories of Marcellus at Syracuse, 212 B.C., Fabius
Maximus at Tarentum (209 B.C.), Flaminius (196 B.C.), Mummius (146
B.C.), Sulla (86 B.C.), and others in the various Greek provinces,
steadily increased the vogue of Greek architecture and the number of
Greek artists in Rome. The temples of the last two centuries B.C., and
some of earlier date, though still Etruscan in plan, were in many cases
strongly Greek in the character of their details. A few have remained to
our time in tolerable preservation. The temple of +Fortuna Virilis+
(really of Fors Fortuna), of the second century (?) B.C., is a
tetrastyle prostyle pseudoperipteral temple with a high _podium_ or
base, a typical Etruscan cella, and a deep porch, now walled up, but
thoroughly Greek in the elegant details of its Ionic order (Fig. 51).
Two circular temples, both called erroneously +Temples of Vesta+, one at
Rome near the Cloaca Maxima, the other at Tivoli, belong among the
monuments of Greek style. The first was probably dedicated to Hercules,
the second probably to the Sibyls; the latter being much the better
preserved of the two. Both were surrounded by peristyles of eighteen
Corinthian columns, and probably covered by domical roofs with gilded
bronze tiles. The Corinthian order appears here complete with its
modillion cornice, but the crispness of the detail and the fineness of
the execution are Greek and not Roman. These temples date from about 72
B.C., though the one at Rome was probably rebuilt in the first century
A.D. (Fig. 52).
[Illustration: FIG. 52.--CIRCULAR TEMPLE. TIVOLI.]
+IMPERIAL ARCHITECTURE; AUGUSTAN AGE.+ Even in the temples of Greek
style Roman conceptions of plan and composition are dominant. The Greek
architect was not free to reproduce textually Greek designs or details,
however strongly he might impress with the Greek character whatever he
touched. The demands of imperial splendor and the building of great
edifices of varied form and complex structure, like the thermæ and
amphitheatres, called for new adaptations and combinations of planning
and engineering. The reign of Augustus (27 B.C.-14 A.D.) inaugurated the
imperial epoch, but many works erected before and after his reign
properly belong to the Augustan age by right of style. In general, we
find in the works of this period the happiest combination of Greek
refinement with Roman splendor. It was in this period that Rome first
assumed the aspect of an opulent and splendid metropolis, though the way
had been prepared for this by the regularization and adornment of the
Roman Forum and the erection of many temples, basilicas, fora, arches,
and theatres during the generation preceding the accession of Augustus.
His reign saw the inception or completion of the portico of Octavia, the
Augustan forum, the Septa Julia, the first Pantheon, the adjoining
Thermæ of Agrippa, the theatre of Marcellus, the first of the imperial
palaces on the Palatine, and a long list of temples, including those of
the Dioscuri (Castor and Pollux), of Mars Ultor, of Jupiter Tonans on
the Capitol, and others in the provinces; besides colonnades, statues,
arches, and other embellishments almost without number.
+LATER IMPERIAL WORKS.+ With the successors of Augustus splendor
increased to almost fabulous limits, as, for instance, in the vast
extent and the prodigality of ivory and gold in the famous Golden House
of Nero. After the great fire in Rome, presumably kindled by the agents
of this emperor, a more regular and monumental system of street-planning
and building was introduced, and the first municipal building-law was
decreed by him. To the reign of Vespasian (68-79 A.D.) we owe the
rebuilding in Roman style and with the Corinthian order of the temple of
Jupiter Capitolinus, the Baths of Titus, and the beginning of the
Flavian amphitheatre or Colosseum. The two last-named edifices both
stood on the site of Nero’s Golden House, of which the greater part was
demolished to make way for them. During the last years of the first
century the arch of Titus was erected, the Colosseum finished,
amphitheatres built at Verona, Pola, Reggio, Tusculum, Nîmes (France),
Constantine (Algiers), Pompeii and Herculanum (these last two cities and
Stabiæ rebuilt after the earthquake of 63 A.D.), and arches, bridges,
and temples erected all over the Roman world.
The first part of the second century was distinguished by the splendid
architectural achievements of the reign of Hadrian (117-138 A.D.) in
Rome and the provinces, especially Athens. Nearly all his works were
marked by great dignity of conception as well as beauty of detail.
During the latter part of the century a very interesting series of
buildings were erected in the Hauran (Syria), in which Greek and Arab
workmen under Roman direction produced examples of vigorous stone
architecture of a mingled Roman and Syrian character.
The most-remarkable thermæ of Rome belong to the third century--those of
Caracalla (211-217 A.D.) and of Diocletian (284-305 A.D.)--their ruins
to-day ranking among the most imposing remains of antiquity. In Syria
the temples of the Sun at Baalbec and Palmyra (273 A.D., under
Aurelian), and the great palace of Diocletian at Spalato, in Dalmatia
(300 A.D.), are still the wonder of the few travellers who reach those
distant spots.
While during the third and fourth centuries there was a marked decline
in purity and refinement of detail, many of the later works of the
period display a remarkable freedom and originality in conception. But
these works are really not Roman, they are foreign, that is, provincial
products; and the transfer of the capital to Byzantium revealed the
increasing degree in which Rome was coming to look to the East for her
strength and her art.
[Illustration: FIG. 53.--TEMPLE OF VENUS AND ROME. PLAN.]
+TEMPLES.+ The Romans built both rectangular and circular temples, and
there was much variety in their treatment. In the rectangular temples a
high _podium_, or basement, was substituted for the Greek stepped
stylobate, and the prostyle plan was more common than the peripteral.
The cella was relatively short and wide, the front porch inordinately
deep, and frequently divided by longitudinal rows of columns into three
aisles. In most cases the exterior of the cella in prostyle temples was
decorated by engaged columns. A barrel vault gave the interior an aspect
of spaciousness impossible with the Greek system of a wooden ceiling
supported on double ranges of columns. In the place of these, free or
engaged columns along the side-walls received the ribs of the vaulting.
Between these ribs the ceiling was richly panelled, or coffered and
sumptuously gilded. The temples of +Fortuna Virilis+ and of +Faustina+
at Rome (the latter built 141 A.D., and its ruins incorporated into the
modern church of S. Lorenzo in Miranda), and the beautiful and admirably
preserved +Maison Carrée+, at Nîmes (France) (4 A.D.) are examples of
this type. The temple of +Concord+, of which only the podium remains,
and the small temple of Julius (both of these in the Forum) illustrate
another form of prostyle temple in which the porch was on a long side of
the cella. Some of the larger temples were peripteral. The temple of the
+Dioscuri+ (Castor and Pollux) in the Forum, was one of the most
magnificent of these, certainly the richest in detail (Fig. 44). Very
remarkable was the double temple of +Venus and Rome+, east of the Forum,
designed by the Emperor Hadrian about 130 A.D. (Fig. 53). It was a vast
pseudodipteral edifice containing two cellas in one structure, their
statue-niches or apses meeting back to back in the centre. The temple
stood in the midst of an imposing columnar peribolus entered by
magnificent gateways. Other important temples have already been
mentioned on p. 91.
Besides the two circular temples already described, the temple of Vesta,
adjoining the House of the Vestals, at the east end of the Forum should
be mentioned. At Baalbec is a circular temple whose entablature curves
inward between the widely-spaced columns until it touches the cella in
the middle of each intercolumniation. It illustrates the caprices of
design which sometimes resulted from the disregard of tradition and the
striving after originality (273 A.D.).
[Illustration: FIG. 54.--PLAN OF THE PANTHEON.]
+THE PANTHEON.+ The noblest of all circular temples of Rome and of the
world was the +Pantheon+. It was built by Hadrian, 117-138 A.D., on the
site of the earlier rectangular temple of the same name erected by
Agrippa. It measures 142 feet in diameter internally; the wall is 20
feet thick and supports a hemispherical dome rising to a height of 140
feet (Figs. 54, 55). Light is admitted solely through a round opening 28
feet in diameter at the top of the dome, the simplest and most
impressive method of illumination conceivable. The rain and snow that
enter produce no appreciable effect upon the temperature of the vast
hall. There is a single entrance, with noble bronze doors, admitting
directly to the interior, around which seven niches, alternately
rectangular and semicircular in plan and fronted by Corinthian columns,
lighten, without weakening, the mass of the encircling wall. This wall
was originally incrusted with rich marbles, and the great dome, adorned
with deep coffering in rectangular panels, was decorated with rosettes
and mouldings in gilt stucco. The dome appears to have been composed of
numerous arches and ribs, filled in and finally coated with concrete.
A recent examination of a denuded portion of its inner surface has
convinced the writer that the interior panelling was executed after, and
not during, its construction, by hewing the panels out of the mass of
brick and concrete, without regard to the form and position of the
origin skeleton of ribs.
[Illustration: FIG. 55.--INTERIOR OF THE PANTHEON.]
[Illustration: FIG. 56.--EXTERIOR OF THE PANTHEON.
(From model in Metropolitan Museum, New York.)]
The exterior (Fig. 56) was less successful than the interior. The gabled
porch of twelve superb granite columns 50 feet high, three-aisled in
plan after the Etruscan mode, and covered originally by a ceiling of
bronze, was a rebuilding with the materials and on the plan of the
original pronaos of the Pantheon of Agrippa. The circular wall behind it
is faced with fine brickwork, and displays, like the dome, many curious
arrangements of discharging arches, reminiscences of traditional
constructive precautions here wholly useless and fictitious because only
skin-deep. A revetment of marble below and plaster above once concealed
this brick facing. The portico, in spite of its too steep gable (once
filled with a “gigantomachia” in gilt bronze) and its somewhat awkward
association with a round building, is nevertheless a noble work, its
capitals in Pentelic marble ranking among the finest known examples of
the Roman Corinthian. Taken as a whole, the Pantheon is one of the great
masterpieces of the world’s architecture.
[Illustration: FIG. 57.--FORUM AND BASILICA OF TRAJAN.]
+FORA AND BASILICAS.+ The fora were the places for general public
assemblage. The chief of those in Rome, the +Forum Magnum+, or +Forum
Romanum+, was at first merely an irregular vacant space, about and in
which, as the focus of the civic life, temples, halls, colonnades, and
statues gradually accumulated. These chance aggregations the systematic
Roman mind reduced in time to orderly and monumental form; successive
emperors extended them and added new fora at enormous cost and with
great splendor of architecture. Those of Julius, Augustus, Vespasian,
and Nerva (or Domitian), adjoining the Roman Forum, were magnificent
enclosures surrounded by high walls and single or double colonnades.
Each contained a temple or basilica, besides gateways, memorial columns
or arches, and countless statues. The +Forum of Trajan+ surpassed all
the rest; it covered an area of thirty-five thousand square yards, and
included, besides the main area, entered through a triumphal arch, the
Basilica Ulpia, the temple of Trajan, and his colossal Doric column of
Victory. Both in size and beauty it ranked as the chief architectural
glory of the city (Fig. 57). The six fora together contained thirteen
temples, three basilicas, eight triumphal arches, a mile of porticos,
and a number of other public edifices.[14] Besides these, a net-work of
colonnades covered large tracts of the city, affording sheltered
communication in every direction, and here and there expanding into
squares or gardens surrounded by peristyles.

Discoveries_, p. 89.]

The public business of Rome, both judicial and commercial, was largely
transacted in the _basilicas_, large buildings consisting usually of a
wide and lofty central nave flanked by lower side-aisles, and
terminating at one or both ends in an apse or semicircular recess called
the _tribune_, in which were the seats for the magistrates. The
side-aisles were separated from the nave by columns supporting a
clearstory wall, pierced by windows above the roofs of the side-aisles.
In some cases the latter were two stories high, with galleries; in
others the central space was open to the sky, as at Pompeii, suggesting
the derivation of the basilica from the open square surrounded by
colonnades, or from the forum itself, with which we find it usually
associated. The most important basilicas in Rome were the +Sempronian+,
the +Æmilian+ (about 54 B.C.), the +Julian+ in the Forum Magnum (51
B.C.), and the +Ulpian+ in the Forum of Trajan (113 A.D.). The last two
were probably open basilicas, only the side-aisles being roofed. The
Ulpian (Fig. 57) was the most magnificent of all, and in conjunction
with the Forum of Trajan formed one of the most imposing of those
monumental aggregations of columnar architecture which contributed so
largely to the splendor of the Roman capital.
These monuments frequently suffered from the burning of their wooden
roofs. It was Constantine who completed the first vaulted and fireproof
basilica, begun by his predecessor and rival, Maxentius, on the site of
the former Temple of Peace (Figs. 58, 59). Its design reproduced on a
grand scale the plan of the tepidarium-halls of the thermæ, the
side-recesses of which were converted into a continuous side-aisle by
piercing arches through the buttress-walls that separated them. Above
the imposing vaults of these recesses and under the cross-vaults of the
nave were windows admitting abundant light. A _narthex_, or porch,
preceded the hall at one end; there were also a side entrance from the
Via Sacra, and an apse or tribune for the magistrates opposite each of
these entrances. The dimensions of the main hall (325 × 85 feet), the
height of its vault (117 feet), and the splendor of its columns and
incrustations excited universal admiration, and exercised a powerful
influence on later architecture.

+THERMÆ.+ The leisure of the Roman people was largely spent in the great
baths, or _thermæ_, which took the place substantially of the modern
club. The establishments erected by the emperors for this purpose were
vast and complex congeries of large and small halls, courts, and
chambers, combined with a masterly comprehension of artistic propriety
and effect in the sequence of oblong, square, oval, and circular
apartments, and in the relation of the greater to the lesser masses.
They were a combination of the Greek _palæstra_ with the Roman _balnea_,
and united in one harmonious design great public swimming-baths, private
baths for individuals and families, places for gymnastic exercises and
games, courts, peristyles, gardens, halls for literary entertainments,
lounging-rooms, and all the complex accommodation required for the
service of the whole establishment. They were built with apparent
disregard of cost, and adorned with splendid extravagance. The earliest
were the +Baths of Agrippa+ (27 B.C.) behind the Pantheon; next may be
mentioned those of +Titus+, built on the substructions of Nero’s Golden
House. The remains of the +Thermæ of Caracalla+ (211 A.D.) form the most
extensive mass of ruins in Rome, and clearly display the admirable
planning of this and similar establishments. A gigantic block of
buildings containing the three great halls for cold, warm, and hot
baths, stood in the centre of a vast enclosure surrounded by private
baths, _exedræ_, and halls for lecture-audiences and other gatherings.
The enclosure was adorned with statues, flower-gardens, and places for
out-door games. The +Baths of Diocletian+ (302 A.D.) embodied this
arrangement on a still more extensive scale; they could accommodate
3,500 bathers at once, and their ruins cover a broad territory near the
railway terminus of the modern city. The church of S. Maria degli Angeli
was formed by Michael Angelo out of the _tepidarium_ of these
baths--a colossal hall 340 × 87 feet, and 90 feet high. The original
vaulting and columns are still intact, and the whole interior most
imposing, in spite of later stucco disfigurements. The circular
_laconicum_ (sweat-room) serves as the porch to the present church. It
was in the building of these great halls that Roman architecture reached
its most original and characteristic expression. Wholly unrelated to any
foreign model, they represent distinctively Roman ideals, both as to
plan and construction.
[Illustration: FIG. 61.--ROMAN THEATRE. (HERCULANUM.)
(From model.)]
[Illustration: FIG. 62.--COLOSSEUM. HALF PLAN.]
+PLACES OF AMUSEMENT.+ The earliest Roman theatres differed from the
Greek in having a nearly semicircular plan, and in being built up from
the level ground, not excavated in a hillside (Fig. 61). The first
theatre was of wood, built by Mummius 145 B.C., and it was not until
ninety years later that stone was first substituted for the more
perishable material, in the theatre of Pompey. The +Theatre of
Marcellus+ (23-13 B.C.) is in part still extant, and later theatres in
Pompeii, Orange (France), and in the Asiatic provinces are in excellent
preservation. The orchestra was not, as in the Greek theatre, reserved
for the choral dance, but was given up to spectators of rank; the stage
was adorned with a permanent architectural background of columns and
arches, and sometimes roofed with wood, and an arcade or colonnade
surrounded the upper tier of seats. The amphitheatre was a still more
distinctively Roman edifice. It was elliptical in plan, surrounding an
elliptical arena, and built up with continuous encircling tiers of
seats. The earliest stone amphitheatre was erected by Statilius Taurus
in the time of Augustus. It was practically identical in design with the
later and much larger Flavian amphitheatre, commonly known as the
+Colosseum+, begun by Vespasian and completed 82 A.D. (Fig. 62). This
immense structure measured 607 × 506 feet in plan and was 180 feet high;
it could accommodate eighty-seven thousand spectators. Engaged columns
of the Tuscan, Ionic, and Corinthian orders decorated three stories of
the exterior; the fourth was a nearly unbroken wall with slender
Corinthian pilasters. Solidly constructed of travertine, concrete, and
tufa, the Colosseum, with its imposing but monotonous exterior, almost
sublime by its scale and seemingly endless repetition, but lacking in
refinement or originality of detail and dedicated to bloody and cruel
sports, was a characteristic product of the Roman character and
civilization. At Verona, Pola, Capua, and many cities in the foreign
provinces there are well-preserved remains of similar structures.
Closely related to the amphitheatre were the circus and the stadium. The
+Circus Maximus+ between the Palatine and Aventine hills was the oldest
of those in Rome. That erected by Caligula and Nero on the site
afterward partly occupied by St. Peter’s, was more splendid, and is said
to have been capable of accommodating over three hundred thousand
spectators after its enlargement in the fourth century. The long, narrow
race-course was divided into two nearly equal parts by a low parapet,
the _spina_, on which were the goals (_metæ_) and many small decorative
structures and columns. One end of the circus, as of the stadium also,
was semicircular; the other was segmental in the circus, square in the
stadium; a colonnade or arcade ran along the top of the building, and
the entrances and exits were adorned with monumental arches.
+TRIUMPHAL ARCHES AND COLUMNS.+ Rome and the provincial cities abounded
in monuments commemorative of victory, usually single or triple arches
with engaged columns and rich sculptural adornments, or single colossal
columns supporting statues. The arches were characteristic products of
Roman design, and some of them deserve high praise for the excellence of
their proportions and the elegance of their details. There were in Rome
in the second century A.D., thirty-eight of these monuments. The +Arch
of Titus+ (71-82 A.D.) is the simplest and most perfect of those still
extant in Rome; the arch of +Septimius Severus+ in the Forum (203 A.D.)
and that of +Constantine+ (330 A.D.) near the Colosseum, are more
sumptuous but less pure in detail. The last-named was in part enriched
with sculptures taken from the earlier arch of Trajan. The statues of
Dacian captives on the attic (_attic_ = a species of subordinate story
added above the main cornice) of this arch were a fortunate addition,
furnishing a _raison-d’être_ for the columns and broken entablatures on
which they rest. Memorial columns of colossal size were erected by
several emperors, both in Rome and abroad. Those of +Trajan+ and of
+Marcus Aurelius+ are still standing in Rome in perfect preservation.
The first was 140 feet high including the pedestal and the statue which
surmounted it; its capital marked the height of the ridge levelled by
the emperor for the forum on which the column stands. Its most striking
peculiarity is the spiral band of reliefs winding around the shaft from
bottom to top and representing the Dacian campaigns of Trajan. The other
column is of similar design and dimensions, but greatly inferior to the
first in execution. Both are really towers, with interior stair-cases
leading to the top.
[Illustration: FIG. 63.--ARCH OF CONSTANTINE.
(From model in Metropolitan Museum, New York.)]
+TOMBS.+ The Romans developed no special and national type of tomb, and
few of their sepulchral monuments were of large dimensions. The most
important in Rome were the pyramid of +Caius Cestius+ (late first
century B.C.), and the circular tombs of +Cecilia Metella+ (60 B.C.),
+Augustus+ (14 A.D.) and +Hadrian+, now the Castle of S. Angelo (138
A.D.). The latter was composed of a huge cone of marble supported on a
cylindrical structure 230 feet in diameter standing on a square podium
300 feet long and wide. The cone probably once terminated in the gilt
bronze pine-cone now in the Giardino della Pigna of the Vatican. In the
Mausoleum of Augustus a mound of earth planted with trees crowned a
similar circular base of marble on a podium 220 feet square, now buried.
The smaller tombs varied greatly in size and form. Some were vaulted
chambers, with graceful internal painted decorations of figures and vine
patterns combined with low-relief enrichments in stucco. Others were
designed in the form of altars or sarcophagi, as at Pompeii; while
others again resembled ædiculæ, little temples, shrines, or small towers
in several stories of arches and columns, as at St. Rémy (France).
+PALACES AND DWELLINGS.+ Into their dwellings the Romans carried all
their love of ostentation and personal luxury. They anticipated in many
details the comforts of modern civilization in their furniture, their
plumbing and heating, and their utensils. Their houses may be divided
into four classes: the palace, the villa, the _domus_ or ordinary house,
and the _insula_ or many-storied tenement built in compact blocks. The
first three alone concern us, and will be taken up in the above order.
The imperial +palaces+ on the Palatine Hill comprised a wide range in
style and variety of buildings, beginning with the first simple house of
Augustus (26 B.C.), burnt and rebuilt 3 A.D. Tiberius, Caligula, and
Nero added to the Augustan group; Domitian rebuilt a second time and
enlarged the palace of Augustus, and Septimius Severus remodelled the
whole group, adding to it his own extraordinary seven-storied palace,
the Septizonium. The ruins of these successive buildings have been
carefully excavated, and reveal a remarkable combination of
dwelling-rooms, courts, temples, libraries, basilicas, baths, gardens,
peristyles, fountains, terraces, and covered passages. These were
adorned with a profusion of precious marbles, mosaics, columns, and
statues. Parts of the demolished palace of Nero were incorporated in the
substructions of the Baths of Titus. The beautiful arabesques and
plaster reliefs which adorned them were the inspiration of much of the
fresco and stucco decoration of the Italian Renaissance. At Spalato, in
Dalmatia, are the extensive ruins of the great +Palace of Diocletian+,
which was laid out on the plan of a Roman camp, with two intersecting
avenues (Fig. 64). It comprised a temple, mausoleum, basilica, and other
structures besides those portions devoted to the purposes of a royal
residence.
[Illustration: FIG. 64.--PALACE OF DIOCLETIAN. SPALATO.]
The +villa+ was in reality a country palace, arranged with special
reference to the prevailing winds, exposure to the sun and shade, and
the enjoyment of a wide prospect. Baths, temples, _exedræ_, theatres,
tennis-courts, sun-rooms, and shaded porticoes were connected with the
house proper, which was built around two or three interior courts or
peristyles. Statues, fountains, and colossal vases of marble adorned the
grounds, which were laid out in terraces and treated with all the
fantastic arts of the Roman landscape-gardener. The most elaborate and
extensive villa was that of +Hadrian+, at Tibur (Tivoli); its ruins,
covering hundreds of acres, form one of the most interesting spots to
visit in the neighborhood of Rome.
[Illustration: FIG. 65.--HOUSE OF PANSA, POMPEII.
s, _Shops_; v, _Vestibule_; f, _Family Rooms_; k, _Kitchen_;
l, _Lavarium_; _P, P, P_, _Peristyles_.]
There are few remains in Rome of the +domus+ or private house. Two,
however, have left remarkably interesting ruins--the +Atrium Vestæ+, or
House of the Vestal Virgins, east of the Forum, a well-planned and
extensive house surrounding a cloister or court; and the +House of
Livia+, so-called, on the Palatine Hill, the walls and decorations of
which are excellently preserved. The typical Roman house in a provincial
town is best illustrated by the ruins of Pompeii and Herculanum, which,
buried by an eruption of Vesuvius in 79 A.D., have been partially
excavated since 1721. The Pompeiian house (Fig. 65) consisted of several
courts or _atria_, some of which were surrounded by colonnades and
called _peristyles_. The front portion was reserved for shops, or
presented to the street a wall unbroken save by the entrance; all the
rooms and chambers opened upon the interior courts, from which alone
they borrowed their light. In the brilliant climate of southern Italy
windows were little needed, as sufficient light was admitted by the
door, closed only by portières for the most part; especially as the
family life was passed mainly in the shaded courts, to which fountains,
parterres of shrubbery, statues, and other adornments lent their
inviting charm. The general plan of these houses seems to have been of
Greek origin, as well as the system of decoration used on the walls.
These, when not wainscoted with marble, were covered with fantastic, but
often artistic, painted decorations, in which an imaginary architecture
as of metal, a fantastic and arbitrary perspective, illusory pictures,
and highly finished figures were the chief elements. These were executed
in brilliant colors with excellent effect. The houses were lightly
built, with wooden ceilings and roofs instead of vaulting, and usually
with but one story on account of the danger from earthquakes. That the
workmanship and decoration were in the capital often superior to what
was to be found in a provincial town like Pompeii, is evidenced by
beautiful wall-paintings and reliefs discovered in Rome in 1879 and now
preserved in the Museo delle Terme. More or less fragmentary remains of
Roman houses have been found in almost every corner of the Roman empire,
but nowhere exhibiting as completely as in Pompeii the typical Roman
arrangement.
+WORKS OF UTILITY.+ A word should be said about Roman engineering works,
which in many cases were designed with an artistic sense of proportion
and form which raises them into the domain of genuine art. Such were
especially the bridges, in which a remarkable effect of monumental
grandeur was often produced by the form and proportions of the arches
and piers, and an appropriate use of rough and dressed masonry, as in
the Pons Ælius (Ponte S. Angelo), the great bridge at Alcantara (Spain),
and the Pont du Gard, in southern France. The aqueducts are impressive
rather by their length, scale, and simplicity, than by any special
refinements of design, except where their arches are treated with some
architectural decoration to form gates, as in the Porta Maggiore, at
Rome.

+INTRODUCTORY.+ The official recognition of Christianity in the year 328
by Constantine simply legalized an institution which had been for three
centuries gathering momentum for its final conquest of the antique
world. The new religion rapidly enlisted in its service for a common
purpose and under a common impulse races as wide apart in blood and
culture as those which had built up the art of imperial Rome. It was
Christianity which reduced to civilization in the West the Germanic
hordes that had overthrown Rome, bringing their fresh and hitherto
untamed vigor to the task of recreating architecture out of the decaying
fragments of classic art. So in the East its life-giving influence awoke
the slumbering Greek art-instinct to new triumphs in the arts of
building, less refined and perfect indeed, but not less sublime than
those of the Periclean age. Long before the Constantinian edict, the
Christians in the Eastern provinces had enjoyed substantial freedom of
worship. Meeting often in the private basilicas of wealthy converts, and
finding these, and still more the great public basilicas, suited to the
requirements of their worship, they early began to build in imitation of
these edifices. There are many remains of these early churches in
northern Africa and central Syria.
+EARLY CHRISTIAN ART IN ROME.+ This was at first wholly sepulchral,
developing in the catacombs the symbols of the new faith. Once
liberated, however, Christianity appropriated bodily for its public
rites the basilica-type and the general substance of Roman architecture.
Shafts and capitals, architraves and rich linings of veined marble, even
the pagan Bacchic symbolism of the vine, it adapted to new uses in its
own service. Constantine led the way in architecture, endowing Bethlehem
and Jerusalem with splendid churches, and his new capital on the
Bosphorus with the first of the three historic basilicas dedicated to
the Holy Wisdom (Hagia Sophia). One of the greatest of innovators, he
seems to have had a special predilection for circular buildings, and the
tombs and baptisteries which he erected in this form, especially that
for his sister Constantia in Rome (known as Santa Costanza, Fig. 66),
furnished the prototype for numberless Italian baptisteries in later
ages.
[Illustration: FIG. 66.--STA. COSTANZA, ROME.]
The Christian basilica (see Figs. 67, 68) generally comprised a broad
and lofty nave, separated by rows of columns from the single or double
side-aisles. The aisles had usually about half the width and height of
the nave, and like it were covered with wooden roofs and ceilings. Above
the columns which flanked the nave rose the lofty clearstory wall,
pierced with windows above the side-aisle roofs and supporting the
immense trusses of the roof of the nave. The timbering of the latter was
sometimes bare, sometimes concealed by a richly panelled ceiling,
carved, gilded, and painted. At the further end of the nave was the
sanctuary or apse, with the seats for the clergy on a raised platform,
the _bema_, in front of which was the altar. Transepts sometimes
expanded to right and left before the altar, under which was the
_confessio_ or shrine of the titular saint or martyr.
An _atrium_ or forecourt surrounded by a covered arcade preceded the
basilica proper, the arcade at the front of the church forming a porch
or _narthex_, which, however, in some cases existed without the atrium.
The exterior was extremely plain; the interior, on the contrary, was
resplendent with incrustations of veined marble and with sumptuous
decorations in glass mosaic (called _opus Grecanicum_) on a blue or
golden ground. Especially rich were the half-dome of the apse and the
wall-space surrounding its arch and called the _triumphal arch_; next in
decorative importance came the broad band of wall beneath the clearstory
windows. Upon these surfaces the mosaic-workers wrought with minute
cubes of colored glass pictures and symbols almost imperishable, in
which the glow of color and a certain decorative grandeur of effect in
the composition went far to atone for the uncouth drawing. With growing
wealth and an increasingly elaborate ritual, the furniture and
equipments of the church assumed greater architectural importance.
A large rectangular space was retained for the choir in front of the
bema, and enclosed by a breast-high parapet of marble, richly inlaid. On
either side were the pulpits or _ambones_ for the Gospel and Epistle.
A lofty canopy was built over the altar, the _baldaquin_, supported on
four marble columns. A few basilicas were built with side-aisles, in two
stories, as in S. Lorenzo and Sta. Agnese. Adjoining the basilica in the
earlier examples were the baptistery and the tomb of the saint, circular
or polygonal buildings usually; but in later times these were replaced
by the font or baptismal chapel in the church and the _confessio_ under
the altar.
[Illustration: FIG. 67.--PLAN OF THE BASILICA OF ST. PAUL.]
Of the two Constantinian basilicas in Rome, the one dedicated to +St.
Peter+ was demolished in the fifteenth century; that of +St. John
Lateran+ has been so disfigured by modern alterations as to be
unrecognizable. The former of the two adjoined the site of the martyrdom
of St. Peter in the circus of Caligula and Nero; it was five-aisled, 380
feet in length by 212 feet in width. The nave was 80 feet wide and 100
feet high, and the disproportionately high clearstory wall rested on
horizontal architraves carried by columns. The impressive dimensions and
simple plan of this structure gave it a majesty worthy of its rank as
the first church of Christendom. +St. Paul beyond the Walls+ (S. Paolo
fuori le mura), built in 386 by Theodosius, resembled St. Peter’s
closely in plan (Figs. 67, 68). Destroyed by fire in 1821, it has been
rebuilt with almost its pristine splendor, and is, next to the modern
St. Peter’s and the Pantheon, the most impressive place of worship in
Rome. +Santa Maria Maggiore+,[15] though smaller in size, is more
interesting because it so largely retains its original aspect, its
Renaissance ceiling happily harmonizing with its simple antique lines.
Ionic columns support architraves to carry the clearstory, as in St.
Peter’s. In most other examples, St. Paul’s included, arches turned from
column to column perform this function. The first known case of such use
of classic columns as arch-bearers was in the palace of Diocletian at
Spalato; it also appears in Syrian buildings of the third and fourth
centuries A.D.
[Footnote 15: Hereafter the abbreviation S. M. will be generally
used instead of the name Santa Maria.]
[Illustration: FIG. 68.--ST. PAUL BEYOND THE WALLS. INTERIOR.]
The basilica remained the model for ecclesiastical architecture in Rome,
without noticeable change either of plan or detail, until the time of
the Renaissance. All the earlier examples employed columns and capitals
taken from ancient ruins, often incongruous and ill-matched in size and
order. +San Clemente+ (1084) has retained almost intact its early
aspect, its choir-enclosure, baldaquin, and ambones having been well
preserved or carefully restored. Other important basilicas are mentioned
in the list of monuments on pages 118, 119.
+RAVENNA.+ The fifth and sixth centuries endowed Ravenna with a number
of notable buildings which, with the exception of the cathedral,
demolished in the last century, have been preserved to our day. Subdued
by the Byzantine emperor Justinian in 537, Ravenna became the
meeting-ground for Early Christian and Byzantine traditions and the
basilican and circular plans are both represented. The two churches
dedicated to St. Apollinaris, +S. Apollinare Nuovo+ (520) in the city,
and +S. Apollinare in Classe+ (538) three miles distant from the city,
in what was formerly the port, are especially interesting for their fine
mosaics, and for the impost-blocks interposed above the capitals of
their columns to receive the springing of the pier-arches. These blocks
appear to be somewhat crude modifications of the fragmentary architraves
or entablatures employed in classic Roman architecture to receive the
springing of vaults sustained by columns, and became common in Byzantine
structures (Fig. 73). The use of external arcading to give some slight
adornment to the walls of the second of the above-named churches, and
the round bell-towers of brick which adjoined both of them, were first
steps toward the development of the “wall-veil” or arcaded decoration,
and of the campaniles, which in later centuries became so characteristic
of north Italian churches (see Chapter XIII.). In Rome the campaniles
which accompany many of the mediæval basilicas are square and pierced
with many windows.
The basilican form of church became general in Italy, a large proportion
of whose churches continued to be built with wooden roofs and with but
slight deviations from the original type, long after the appearance of
the Gothic style. The chief departures from early precedent were in the
exterior, which was embellished with marble incrustations as in
S. Miniato (Florence); or with successive stories of wall-arcades, as in
many churches in Pisa and Lucca (see Fig. 90); until finally the
introduction of clustered piers, pointed arches, and vaulting, gradually
transformed the basilican into the Italian Romanesque and Gothic styles.
+SYRIA AND THE EAST.+ In Syria, particularly the central portion, the
Christian architecture of the 3d to 8th centuries produced a number of
very interesting monuments. The churches built by Constantine in
Syria--the Church of the Nativity in Bethlehem (nominally built by his
mother), of the Ascension at Jerusalem, the magnificent octagonal church
on the site of the Temple, and finally the somewhat similar church at
Antioch--were the most notable Christian monuments in Syria. The first
three on the list, still extant in part at least, have been so altered
by later additions and restorations that their original forms are only
approximately known from early descriptions. They were all of large
size, and the octagonal church on the Temple platform was of exceptional
magnificence.[16] The columns and a part of the marble incrustations of
the early design are still visible in the “Mosque of Omar,” but most of
the old work is concealed by the decoration of tiles applied by the
Moslems, and the whole interior aspect altered by the wood-and-plaster
dome with which they replaced the simpler roof of the original.
[Footnote 16: Fergusson (_History of Architecture_, vol. ii., pp.
408, 432) contends that this was the real Constantinian church of
the Holy Sepulchre, and that the one called to-day by that name
was erected by the Crusaders in the twelfth century. The more
general view is that the latter was originally built by
Constantine as the Church of the Sepulchre, though subsequently
much altered, and that the octagonal edifice was also his work,
but erected under some other name. Whether this church was later
incorporated in the “Mosque of Omar,” or merely furnished some of
the materials for its construction, is not quite clear.]
[Illustration: FIG. 69.--CHURCH AT KALB LOUZEH.]
Christian architecture in Syria soon, however, diverged from Roman
traditions. The abundance of hard stone, the total lack of clay or
brick, the remoteness from Rome, led to a peculiar independence and
originality in the forms and details of the ecclesiastical as well as of
the domestic architecture of central Syria. These innovations upon Roman
models resulted in the development of distinct types which, but for the
arrest of progress by the Mohammedan conquest in the seventh century,
would doubtless have inaugurated a new and independent style of
architecture. Piers of masonry came to replace the classic column, as at
Tafkha (third or fourth century), Rouheiha and Kalb Louzeh (fifth
century? Fig. 69); the ceilings in the smaller churches were often
formed with stone slabs; the apse was at first confined within the main
rectangle of the plan, and was sometimes square. The exterior assumed a
striking and picturesque variety of forms by means of turrets, porches,
and gables. Singularly enough, vaulting hardly appears at all, though
the arch is used with fine effect. Conventional and monastic groups of
buildings appear early in Syria, and that of +St. Simeon Stylites+ at
Kelat Seman is an impressive and interesting monument. Four three-aisled
wings form the arms of a cross, meeting in a central octagonal open
court, in the midst of which stood the column of the saint. The eastern
arm of the cross forms a complete basilica of itself, and the whole
cross measures 330 × 300 feet. Chapels, cloisters, and cells adjoin the
main edifice.
[Illustration: FIG. 70.--CATHEDRAL AT BOZRAH.]
Circular and polygonal plans appear in a number of Syrian examples of
the early sixth century. Their most striking feature is the inscribing
of the circle or polygon in a square which forms the exterior outline,
and the use of four niches to fill out the corners. This occurs at Kelat
Seman in a small double church, perhaps the tomb and chapel of a martyr;
in the cathedral at +Bozrah+ (Fig. 70), and in the small domical church
of +St. George+ at +Ezra+. These were probably the prototypes of many
Byzantine churches like St. Sergius at Constantinople, and San Vitale at
Ravenna (Fig. 74), though the exact dates of the Syrian churches are not
known. The one at Ezra is the only one of the three which has a dome,
the others having been roofed with wood.
The interesting domestic architecture of this period is preserved in
whole towns and villages in the Hauran, which, deserted at the Arab
conquest, have never been reoccupied and remain almost intact but for
the decay of their wooden roofs. They are marked by dignity and
simplicity of design, and by the same picturesque massing of gables and
roofs and porches which has already been remarked of the churches. The
arches are broad, the columns rather heavy, the mouldings few and
simple, and the scanty carving vigorous and effective, often strongly
Byzantine in type.
Elsewhere in the Eastern world are many early churches of which even the
enumeration would exceed the limits of this work. Salonica counts a
number of basilicas and several domical churches. The church of +St.
George+, now a mosque, is of early date and thoroughly Roman in plan and
section, of the same class with the Pantheon and the tomb of Helena, in
both of which a massive circular wall is lightened by eight niches. At
Angora (Ancyra), Hierapolis, Pergamus, and other points in Asia Minor;
in Egypt, Nubia, and Algiers, are many examples of both circular and
basilican edifices of the early centuries of Christianity. In
Constantinople there remains but a single representative of the
basilican type, the church of +St. John Studius+, now the Emir Akhor
mosque.

+ORIGIN AND CHARACTER.+ The decline and fall of Rome arrested the
development of the basilican style in the West, as did the Arab conquest
later in Syria. It was otherwise in the new Eastern capital founded by
Constantine in the ancient Byzantium, which was rising in power and
wealth while Rome lay in ruins. Situated at the strategic point of the
natural highway of commerce between East and West, salubrious and
enchantingly beautiful in its surroundings, the new capital grew rapidly
from provincial insignificance to metropolitan importance. Its founder
had embellished it with an extraordinary wealth of buildings, in which,
owing to the scarcity of trained architects, quantity and cost doubtless
outran quality. But at least the tameness of blindly followed precedent
was avoided, and this departure from traditional tenets contributed
undoubtedly to the originality of Byzantine architecture. A large part
of the artisans employed in building were then, as now, from Asia Minor
and the Ægean Islands, Greek in race if not in name. An Oriental taste
for brilliant and harmonious color and for minute decoration spread over
broad surfaces must have been stimulated by trade with the Far East and
by constant contact with Oriental peoples, costumes, and arts. An
Asiatic origin may also be assigned to the methods of vaulting employed,
far more varied than the Roman, not only in form but also in materials
and processes. From Roman architecture, however, the Byzantines borrowed
the fundamental notion of their structural art; that, namely, of
distributing the weights and strains of their vaulted structures upon
isolated and massive points of support, strengthened by deep buttresses,
internal or external, as the case might be. Roman, likewise, was the use
of polished monolithic columns, and the incrustation of the piers and
walls with panels of variegated marble, as well as the decoration of
plastered surfaces by fresco and mosaic, and the use of _opus sectile_
and _opus Alexandrinum_ for the production of sumptuous marble
pavements. In the first of these processes the color-figures of the
pattern are formed each of a single piece of marble cut to the shape
required; in the second the pattern is compounded of minute squares,
triangles, and curved pieces of uniform size. Under these combined
influences the artists of Constantinople wrought out new problems in
construction and decoration, giving to all that they touched a new and
striking character.
There is no absolute line of demarcation, chronological, geographical,
or structural, between Early Christian and Byzantine architecture. But
the former was especially characterized by the basilica with three or
five aisles, and the use of wooden roofs even in its circular edifices;
the vault and dome, though not unknown, being exceedingly rare.
Byzantine architecture, on the other hand, rarely produced the simple
three-aisled or five-aisled basilica, and nearly all its monuments were
vaulted. The dome was especially frequent, and Byzantine architecture
achieved its highest triumphs in the use of the _pendentive_, as the
triangular spherical surfaces are called, by the aid of which a dome can
be supported on the summits of four arches spanning the four sides of a
square, as explained later. There is as little uniformity in the plans
of Byzantine buildings as in the forms of the vaulting. A few types of
church-plan, however, predominated locally in one or another centre; but
the controlling feature of the style was the dome and the constructive
system with which it was associated. The dome, it is true, had long been
used by the Romans, but always on a circular plan, as in the Pantheon.
It is also a fact that pendentives have been found in Syria and Asia
Minor older than the oldest Byzantine examples. But the special feature
characterizing the Byzantine dome on pendentives was its almost
exclusive association with plans having piers and columns or aisles,
with the dome as the central and dominant feature of the complex design
(see plans, Figs. 74, 75, 78). Another strictly Byzantine practice was
the piercing of the lower portion of the dome with windows forming a
circle or crown, and the final development of this feature into a high
drum.
+CONSTRUCTION.+ Still another divergence from Roman methods was in the
substitution of brick and stone masonry for concrete. Brick was used for
the mass as well as the facing of walls and piers, and for the vaulting
in many buildings mainly built of stone. Stone was used either alone or
in combination with brick, the latter appearing in bands of four or five
courses at intervals of three or four feet. In later work a regular
alternation of the two materials, course for course, was not uncommon.
In piers intended to support unusually heavy loads the stone was very
carefully cut and fitted, and sometimes tied and clamped with iron.
Vaults were built sometimes of brick, sometimes of cut stone; in a few
cases even of earthenware jars fitting into each other, and laid up in a
continuous contracting spiral from the base to the crown of a dome, as
in San Vitale at Ravenna. Ingenious processes for building vaults
without centrings were made use of--processes inherited from the
drain-builders of ancient Assyria, and still in vogue in Armenia,
Persia, and Asia Minor. The groined vault was common, but always
approximated the form of a dome, by a longitudinal convexity upward in
the intersecting vaults. The aisles of Hagia Sophia[17] display a
remarkable variety of forms in the vaulting.
[Footnote 17: “St. Sophia,” the common name of this church, is a
misnomer. It was not dedicated to a saint at all, but to the
Divine Wisdom (Hagia Sophia), which name the Turks have retained
in the softened form “Aya Sofia.”]
[Illustration: FIG. 71.--DIAGRAM OF PENDENTIVES.]
+DOMES.+ The dome, as we have seen, early became the most characteristic
feature of Byzantine architecture; and especially the dome on
pendentives. If a hemisphere be cut by five planes, four perpendicular
to its base and bounding a square inscribed therein, and the fifth plane
parallel to the base and tangent to the semicircular intersections made
by the first four, there will remain of the original surface only four
triangular spaces bounded by arcs of circles. These are called
_pendentives_ (Fig. 71 a). When these are built up of masonry, each
course forms a species of arch, by virtue of its convexity. At the crown
of the four arches on which they rest, these courses meet and form a
complete circle, perfectly stable and capable of sustaining any
superstructure that does not by excessive weight disrupt the whole
fabric by overthrowing the four arches which support it. Upon these
pendentives, then, a new dome may be started of any desired curvature,
or even a cylindrical drum to support a still loftier dome, as in the
later churches (Fig. 71 b). This method of covering a square is simpler
than the groined vault, having no sharp edges or intersections; it is at
least as effective architecturally, by reason of its greater height in
the centre; and is equally applicable to successive bays of an oblong,
cruciform, and even columnar building. In the great cisterns at
Constantinople vast areas are covered by rows of small domes supported
on ranges of columns.
The earlier domes were commonly pierced with windows at the base, this
apparent weakening of the vault being compensated for by strongly
buttressing the piers between the windows, as in Hagia Sophia. Here
forty windows form a crown of light at the spring of the dome, producing
an effect almost as striking as that of the simple _oculus_ of the
Pantheon, and celebrated by ancient writers in the most extravagant
terms. In later and smaller churches a high drum was introduced beneath
the dome, in order to secure, by means of longer windows, more light
than could be obtained by merely piercing the diminutive domes.
Buttressing was well understood by the Byzantines, whose plans were
skilfully devised to provide internal abutments, which were often
continued above the roofs of the side-aisles to prop the main vaults,
precisely as was done by the Romans in their thermæ and similar halls.
But the Byzantines, while adhering less strictly than the Romans to
traditional forms and processes, and displaying much more ready
contrivance and special adaptation of means to ends, never worked out
this pregnant structural principle to its logical conclusion as did the
Gothic architects of Western Europe a few centuries later.
+DECORATION+. The exteriors of Byzantine buildings (except in some of
the small churches of late date) were generally bare and lacking in
beauty. The interiors, on the contrary, were richly decorated, color
playing a much larger part than carving in the designs. Painting was
resorted to only in the smaller buildings, the more durable and splendid
medium of mosaic being usually preferred. This was, as a rule, confined
to the vaults and to those portions of the wall-surfaces embraced by the
vaults above their springing. The colors were brilliant, the background
being usually of gold, though sometimes of blue or a delicate green.
Biblical scenes, symbolic and allegorical figures and groups of saints
adorned the larger areas, particularly the half-dome of the apse, as in
the basilicas. The smaller vaults, the soffits of arches, borders of
pictures, and other minor surfaces, received a more conventional
decoration of crosses, monograms, and set patterns.
[Illustration: FIG. 72.--SPANDRIL. HAGIA SOPHIA.]
The walls throughout were sheathed with slabs of rare marble in panels
so disposed that the veining should produce symmetrical figures. The
panels were framed in billet-mouldings, derived perhaps from classic
dentils; the billets or projections on one side the moulding coming
opposite the spaces on the other. This seems to have been a purely
Byzantine feature.
+CARVED DETAILS.+ Internally the different stories were marked by
horizontal bands and cornices of white or inlaid marble richly carved.
The arch-soffits, the archivolts or bands around the arches, and the
spandrils between them were covered with minute and intricate incised
carving. The motives used, though based on the acanthus and anthemion,
were given a wholly new aspect. The relief was low and flat, the leaves
sharp and crowded, and the effect rich and lacelike, rather than
vigorous. It was, however, well adapted to the covering of large areas
where general effect was more important than detail. Even the capitals
were treated in the same spirit. The impost-block was almost universal,
except where its use was rendered unnecessary by giving to the capital
itself the massive pyramidal form required to receive properly the
spring of the arch or vault. In such cases (more frequent in
Constantinople than elsewhere) the surface of the capital was simply
covered with incised carving of foliage, basketwork, monograms, etc.;
rudimentary volutes in a few cases recalling classic traditions (Figs.
72, 73). The mouldings were weak and poorly executed, and the vigorous
profiles of classic cornices were only remotely suggested by the
characterless aggregations of mouldings which took their place.

[Illustration: FIG. 75.--PLAN OF HAGIA SOPHIA.]
[Illustration: FIG. 76.--SECTION OF HAGIA SOPHIA.]
+PLANS.+ The remains of Byzantine architecture are almost exclusively of
churches and baptisteries, but the plans of these are exceedingly
varied. The first radical departure from the basilica-type seems to have
been the adoption of circular or polygonal plans, such as had usually
served only for tombs and baptisteries. The Baptistery of St. John at
Ravenna (early fifth century) is classed by many authorities as a
Byzantine monument. In the early years of the sixth century the adoption
of this model had become quite general, and with it the development of
domical design began to advance. The church of +St. Sergius+ at
Constantinople (Fig. 74), originally joined to a short basilica
dedicated to St. Bacchus (afterward destroyed by the Turks), as in the
double church at Kelat Seman, was built about 520; that of +San Vitale+
at Ravenna was begun a few years later; both are domical churches on an
octagonal plan, with an exterior aisle. Semicircular niches--four in St.
Sergius and eight in San Vitale--projecting into the aisle, enlarge
somewhat the area of the central space and give variety to the internal
effect. The origin of this characteristic feature may be traced to the
eight niches of the Pantheon, through such intermediate examples as the
temple of Minerva Medica at Rome. The true pendentive does not appear in
these two churches. Timidly employed up to that time in small
structures, it received a remarkable development in the magnificent
church of +Hagia Sophia+, built by Anthemius of Tralles and Isodorus of
Miletus, under Justinian, 532-538 A.D. In the plan of this marvellous
edifice (Fig. 75) the dome rests upon four mighty arches bounding a
square, into two of which open the half-domes of semicircular apses.
These apses are penetrated and extended each by two smaller niches and a
central arch, and the whole vast nave, measuring over 200 × 100 feet, is
flanked by enormously wide aisles connecting at the front with a
majestic narthex. Huge transverse buttresses, as in the Basilica of
Constantine (with whose structural design this building shows striking
affinities), divide the aisles each into three sections. The plan
suggests that of St. Sergius cut in two, with a lofty dome on
pendentives over a square plan inserted between the halves. Thus was
secured a noble and unobstructed hall of unrivalled proportions and
great beauty, covered by a combination of half-domes increasing in span
and height as they lead up successively to the stupendous central vault,
which rises 180 feet into the air and fitly crowns the whole. The
imposing effect of this low-curved but loftily-poised dome, resting as
it does upon a crown of windows, and so disposed that its summit is
visible from every point of the nave (as may be easily seen from an
examination of the section, Fig. 76), is not surpassed in any interior
ever erected.
[Illustration: FIG. 77.--INTERIOR OF HAGIA SOPHIA,
CONSTANTINOPLE.]
The two lateral arches under the dome are filled by clearstory walls
pierced by twelve windows, and resting on arcades in two stories carried
by magnificent columns taken from ancient ruins. These separate the nave
from the side-aisles, which are in two stories forming galleries, and
are vaulted with a remarkable variety of groined vaults. All the masses
are disposed with studied reference to the resistance required by the
many and complex thrusts exerted by the dome and other vaults. That the
earthquakes of one thousand three hundred and fifty years have not
destroyed the church is the best evidence of the sufficiency of these
precautions.
Not less remarkable than the noble planning and construction of this
church was the treatment of scale and decoration in its interior design.
It was as conspicuously the masterpiece of Byzantine architecture as the
Parthenon was of the classic Greek. With little external beauty, it is
internally one of the most perfectly composed and beautifully decorated
halls of worship ever erected. Instead of the simplicity of the Pantheon
it displays the complexity of an organism of admirably related parts.
The division of the interior height into two stories below the spring of
the four arches, reduces the component parts of the design to moderate
dimensions, so that the scale of the whole is more easily grasped and
its vast size emphasized by the contrast. The walls are incrusted with
precious marbles up to the spring of the vaulting; the capitals,
spandrils, and soffits are richly and minutely carved with incised
ornament, and all the vaults covered with splendid mosaics. Dimmed by
the lapse of centuries and disfigured by the vandalism of the Moslems,
this noble interior, by the harmony of its coloring and its impressive
grandeur, is one of the masterpieces of all time (Fig. 77).
+LATER CHURCHES.+ After the sixth century no monuments were built at all
rivalling in scale the creations of the former period. The later
churches were, with few exceptions, relatively small and trivial.
Neither the plan nor the general aspect of Hagia Sophia seems to have
been imitated in these later works. The crown of dome-windows was
replaced by a cylindrical drum under the dome, which was usually of
insignificant size. The exterior was treated more decoratively than
before, by means of bands and incrustations of colored marble, or
alternations of stone and brick; and internally mosaic continued to be
executed with great skill and of great beauty until the tenth century,
when the art rapidly declined. These later churches, of which a number
were spared by the Turks, are, therefore, generally pleasing and elegant
rather than striking or imposing.
[Illustration: FIG. 78.--PLAN OF ST. MARK’S, VENICE.]
[Illustration: FIG. 79.--INTERIOR OF ST. MARK’S.]
+FOREIGN MONUMENTS.+ The influence of Byzantine art was wide-spread,
both in Europe and Asia. The leading city of civilization through the
Dark Ages, Constantinople influenced Italy through her political and
commercial relations with Ravenna, Genoa, and Venice. The church of +St.
Mark+ in the latter city was one result of this influence (Figs. 78,
79). Begun in 1063 to replace an earlier church destroyed by fire, it
received through several centuries additions not always Byzantine in
character. Yet it was mainly the work of Byzantine builders, who copied
most probably the church of the Apostles at Constantinople, built by
Justinian. The picturesque but wholly unstructural use of columns in the
entrance porches, the upper parts of the façade, the wooden cupolas over
the five domes, and the pointed arches in the narthex, are deviations
from Byzantine traditions dating in part from the later Middle Ages
Nothing could well be conceived more irrational, from a structural point
of view, than the accumulation of columns in the entrance-arches; but
the total effect is so picturesque and so rich in color, that its
architectural defects are easily overlooked. The external veneering of
white and colored marble occurs rarely in the East, but became a
favorite practice in Venice, where it continued in use for five hundred
years. The interior of St. Mark’s, in some respects better preserved
than that of Hagia Sophia, is especially fine in color, though not equal
in scale and grandeur to the latter church. With its five domes it has
less unity of effect than Hagia Sophia, but more of the charm of
picturesqueness, and its less brilliant and simpler lighting enhances
the impressiveness of its more modest dimensions.
In Russia and Greece the Byzantine style has continued to be the
official style of the Greek Church. The Russian monuments are for the
most part of a somewhat fantastic aspect, the Muscovite taste having
introduced many innovations in the form of bulbous domes and other
eccentric details. In Greece there are few large churches, and some of
the most interesting, like the Cathedral at Athens, are almost toy-like
in their diminutiveness. On +Mt. Athos+ (Hagion Oros) is an ancient
monastery which still retains its Byzantine character and traditions. In
Armenia (as at Ani, Etchmiadzin, etc.) are also interesting examples of
late Armeno-Byzantine architecture, showing applications to exterior
carved detail of elaborate interlaced ornament looking like a re-echo of
Celtic MSS. illumination, itself, no doubt, originating in Byzantine
traditions. But the greatest and most prolific offspring of Byzantine
architecture appeared after the fall of Constantinople (1453) in the new
mosque-architecture of the victorious Turks.
