DIAMOND NECKLACE, THE AFFAIR OF THE, a mysterious incident at the court

of Louis XVI. of France, which involved the queen Marie Antoinette. The

Parisian jewellers Boehmer and Bassenge had spent some years collecting

stones for a necklace which they hoped to sell to Madame Du Barry, the

favourite of Louis XV., and after his death to Marie Antoinette. In 1778

Louis XVI. proposed to the queen to make her a present of the necklace,

which cost 1,600,000 livres. But the queen is said to have refused it,

saying that the money would be better spent equipping a man-of-war.

According to others, Louis XVI. himself changed his mind. After having

vainly tried to place the necklace outside of France, the jewellers

attempted again in 1781 to sell it to Marie Antoinette after the birth

of the dauphin. It was again refused, but it was evident that the queen

regretted not being able to acquire it.

At that time there was a personage at the court whom Marie Antoinette

particularly detested. It was the cardinal Louis de Rohan, formerly

ambassador at Vienna, whence he had been recalled in 1774, having

incurred the queen's displeasure by revealing to the empress Maria

Theresa the frivolous actions of her daughter, a disclosure which

brought a maternal reprimand, and for having spoken lightly of Maria

Theresa in a letter of which Marie Antoinette learned the contents.

After his return to France the cardinal was anxious to regain the favour

of the queen in order to obtain the position of prime minister. In March

1784 he entered into relations with a certain Jeanne de St Remy de

Valois, a descendant of a bastard of Henry II., who after many

adventures had married a _soi-disant_ comte de Lamotte, and lived on a

small pension which the king granted her. This adventuress soon gained

the greatest ascendancy over the cardinal, with whom she had intimate

relations. She persuaded him that she had been received by the queen and

enjoyed her favour; and Rohan resolved to use her to regain the queen's

good will. The comtesse de Lamotte assured the cardinal that she was

making efforts on his behalf, and soon announced to him that he might

send his justification to Marie Antoinette. This was the beginning of a

pretended correspondence between Rohan and the queen, the adventuress

duly returning replies to Rohan's notes, which she affirmed to come from

the queen. The tone of the letters became very warm, and the cardinal,

convinced that Marie Antoinette was in love with him, became ardently

enamoured of her. He begged the countess to obtain a secret interview

for him with the queen, and a meeting took place in August 1784 in a

grove in the garden at Versailles between him and a lady whom the

cardinal believed to be the queen herself. Rohan offered her a rose, and

she promised him that she would forget the past. Later a certain Marie

Lejay (renamed by the comtesse "Baronne Gay d'Oliva," the last word

being apparently an anagram of Valoi), who resembled Marie Antoinette,

stated that she had been engaged to play the role of queen in this

comedy. In any case the countess profited by the cardinal's conviction

to borrow from him sums of money destined ostensibly for the queen's

works of charity. Enriched by these, the countess was able to take an

honourable place in society, and many persons believed her relations

with Marie Antoinette, of which she boasted openly and unreservedly, to

be genuine. It is still an unsettled question whether she simply

mystified people, or whether she was really employed by the queen for

some unknown purpose, perhaps to ruin the cardinal. In any case the

jewellers believed in the relations of the countess with the queen, and

they resolved to use her to sell their necklace. She at first refused

their commission, then accepted it. On the 21st of January 1785 she

announced that the queen would buy the necklace, but that not wishing to

treat directly, she left the affair to a high personage. A little while

later Rohan came to negotiate the purchase of the famous necklace for

the 1,600,000 livres, payable in instalments. He said that he was

authorized by the queen, and showed the jewellers the conditions of the

bargain approved in the handwriting of Marie Antoinette. The necklace

was given up. Rohan took it to the countess's house, where a man, in

whom Rohan believed he recognized a valet of the queen, came to fetch

it. Madame de Lamotte had told the cardinal that Marie Antoinette would

make him a sign to indicate her thanks, and Rohan believed that she did

make him a sign. Whether it was so, or merely chance or illusion, no one

knows. But it is certain that the cardinal, convinced that he was acting

for the queen, had engaged the jewellers to thank her; that Boehmer and

Bassenge, before the sale, in order to be doubly sure, had sent word to

the queen of the negotiations in her name; that Marie Antoinette had

allowed the bargain to be concluded, and that after she had received a

letter of thanks from Boehmer, she had burned it. Meanwhile the "comte

de Lamotte" appears to have started at once for London, it is said with

the necklace, which he broke up in order to sell the stones.

When the time came to pay, the comtesse de Lamotte presented the

cardinal's notes; but these were insufficient, and Boehmer complained to

the queen, who told him that she had received no necklace and had never

ordered it. She had the story of the negotiations repeated for her. Then

followed a _coup de theatre_. On the 15th of August 1785, Assumption

day, when the whole court was awaiting the king and queen in order to go

to the chapel, the cardinal de Rohan, who was preparing to officiate,

was arrested and taken to the Bastille. He was able, however, to destroy

the correspondence exchanged, as he thought, with the queen, and it is

not known whether there was any connivance of the officials, who did not

prevent this, or not. The comtesse de Lamotte was not arrested until the

18th of August, after having destroyed her papers. The police set to

work to find all her accomplices, and arrested the girl Oliva and a

certain Reteaux de Villette, a friend of the countess, who confessed

that he had written the letters given to Rohan in the queen's name, and

had imitated her signature on the conditions of the bargain. The famous

charlatan Cagliostro was also arrested, but it was recognized that he

had taken no part in the affair. The cardinal de Rohan accepted the

parlement of Paris as judges. A sensational trial resulted (May 31,

1786) in the acquittal of the cardinal, of the girl Oliva and of

Cagliostro. The comtesse de Lamotte was condemned to be whipped, branded

and shut up in the Salpetriere. Her husband was condemned, in his

absence, to the galleys for life. Villette was banished.

Public opinion was much excited by this trial. It is generally believed

that Marie Antoinette was stainless in the matter, that Rohan was an

innocent dupe, and that the Lamottes deceived both for their own ends.

People, however, persisted in the belief that the queen had used the

countess as an instrument to satisfy her hatred of the cardinal de

Rohan. Various circumstances fortified this belief, which contributed to

render Marie Antoinette very unpopular--her disappointment at Rohan's

acquittal, the fact that he was deprived of his charges and exiled to

the abbey of la Chaise-Dieu, and finally the escape of the comtesse de

Lamotte from the Salpetriere, with the connivance, as people believed,

of the court. The adventuress, having taken refuge abroad, published

_Memoires_ in which she accused the queen. Her husband also wrote

_Memoires_, and lived until 1831, after having, it is said, received

subsidies from Louis XVIII.

DIANA, in Roman mythology, an old Italian goddess, in later times

identified with the Greek Artemis (q.v.). That she was originally an

independent Italian deity is shown by her name, which is the feminine

form of Janus (= Dianus). She is essentially the goddess of the moon and

light generally, and presides over wood, plain and water, the chase and

war. As the goddess of childbirth, she was known, like Juno, by the name

of Lucina, the "bringer to light." As the moon-goddess she was also

identified with Hecate, and invoked as "three-formed" in reference to

the phases of the moon. Her most celebrated shrine was in a grove at

Aricia (whence her title of Nemorensis) near the modern lake of Nemi.

Here she was worshipped side by side with a male deity Virbius, a god of

the forest and the chase. This Virbius was subsequently identified with

Hippolytus, the favourite of Artemis, who was said to have been brought

to life by Aesculapius and conducted by Diana to Aricia (Ovid, _Fasti_,

iii. 263, vi. 731, _Metam._ xv. 497; Virgil, _Aeneid_, vii. 761). A

barbarous custom, perhaps reminiscent of human sacrifice once offered to

her, prevailed in connexion with her ritual here; her priest, called

_Rex Nemorensis_, who was a runaway slave, was obliged to qualify for

office by slaying his predecessor in single combat (Strabo v. p. 239;

Suetonius, _Caligula_, 35). This led to the identification of Diana with

the Tauric Artemis, whose image was said to have been removed by Orestes

to the grove of Aricia (see ARICINI).

After the destruction of Alba Longa this grove was for a long time the

united sanctuary of the neighbouring Latin and Rutulian cities, until at

last it was extinguished beneath the supremacy of Rome. The festival of

the goddess was on the ides (13th) of August, the full moon of the hot

season. She was worshipped with torches, her aid was sought by women

seeking a happy deliverance in childbirth, and many votive offerings

have been found on the site. The worship of Diana was brought to Rome by

Latin plebeians, and hence she was regarded as the protectress of the

lower classes, and especially of slaves. In accordance with this, her

most important temple was that on the Aventine, the chief seat of the

plebeians, founded by Servius Tullius, originally as a sanctuary of the

Latin league (Dion. Halic. iv. 26). No man was allowed to enter the

temple, and on the day of its dedication (August 13) the slaves kept

holiday (Plutarch, _Quaest. Rom._ 100). This Diana was identified with

the sister of Apollo, and at the secular games she was worshipped simply

as Artemis. Another celebrated sanctuary of Diana was that on the slopes

of Mount Tifata near Capua (where she was worshipped under the name of

Tifatina), a sanctuary specially favoured by Sulla and Vespasian. As

Noctiluca ("giving light by night") she had a sanctuary on the Palatine

which was kept illuminated throughout the night (Varro, _L.L._ v. 68).

On the Nemi priesthood see J. G. Frazer, _Golden Bough_.

DIANA MONKEY, a West African representative of the guenon monkeys taking

its name, _Cercopithecus diana_, from the presence of a white crescent

on the forehead; another characteristic feature being the pointed white

beard. The general colour of the fur is greyish, with a deep tinge of

chestnut from the middle of the back to the root of the tail. Together

with _C. neglectus_ of East and Central Africa, _C. ignitus_ of Liberia,

and _C. roloway_ of the Gold Coast, the diana represents the special

subgenus of guenons known as _Pogonocebus_. Although the diana monkey is

commonly seen in menageries, little is known of its habits in the wild

state.

DIANE DE FRANCE (1538-1619), duchess of Montmorency and Angouleme, was

the natural daughter of Henry II. of France and a young Piedmontese,

Filippe Duc. The constable de Montmorency went so far as to assert that

of all the children of Henry II. Diane was the only one who resembled

him. Catherine de' Medici was greatly incensed at this affront, and took

her revenge by having the constable disgraced on the death of Henry II.

Brantome is loud in praise of Diane. She was a perfect horsewoman and

dancer, played several musical instruments, knew Spanish and Italian,

and "estoit tres belle de visage et de taille." Legitimated in 1547, she

was married in 1553 to Horace Farnese, second son of the duke of Parma,

but her husband was killed soon afterwards at the siege of Hesdin. In

order to assure his position, the constable de Montmorency wished to

marry her to his eldest son, Francis. This was a romantic adventure, for

Francis had clandestinely married Mademoiselle de Piennes. The constable

dissolved this union, and after lengthy negotiations obtained the

dispensation of the pope. On the 3rd of May 1559 Francis married Diane.

A wise and moderate woman, Diane undoubtedly helped to make Francis de

Montmorency one of the leaders of the party of the _politiques_. Again a

widow in 1579, she had some influence at the court of Henry III., and

negotiated his reconciliation with Henry of Navarre (1588). She retained

her influence in the reign of Henry IV., conveyed the bodies of

Catherine de' Medici and Henry III. to St Denis, and died in 1619 at her

hotel of Angouleme.

See Brantome, ed. by Lalanne, in the _Coll de la societe d'histoire de

France_, vol. viii. (1875); J. de Thou, _Historia sui temporis..._

(1733); Matthieu de Morgues, _Oraison funebre de Diane de France_

(Paris, 1619).

DIANE DE POITIERS (1499-1566), duchess of Valentinois, and mistress of

Henry II. of France, was the daughter of Jean de Poitiers, seigneur de

St Vallier, who came of an old family of Dauphine. In 1515 she married

Louis de Breze, grand seneschal of Normandy, by whom she had two

daughters. She became a widow in 1533, but soon replaced her husband by

a more illustrious lover, the king's second son, Henry, who became

dauphin in 1536. Although he was ten years younger than Diane, she

inspired the young prince with a profound passion, which lasted until

his death. The accession of Henry II. in 1547 was also the accession of

Diane: she was virtual queen, while Henry's lawful wife, Catherine de'

Medici, lived in comparative obscurity. The part Diane played, however,

must not be exaggerated. More rapacious than ambitious, she concerned

herself little with government, but devoted her energies chiefly to

augmenting her income, and providing for her family and friends. Henry

was the most prodigal of lovers, and gave her all rights over the duchy

of Valentinois. Although she showed great tact in her dealings with the

queen, Catherine drove her from the court after Henry's death, and

forced her to restore the crown jewels and to accept Chaumont in

exchange for Chenonceaux. Diane retired to her chateau at Anet, where

she died in 1566.

Several historians relate that she had been the mistress of Francis I.

before she became the dauphin's mistress, and that she gave herself to

the king in order to obtain the pardon of her father, who had been

condemned to death as an accomplice of the constable de Bourbon. This

rumour, however, has no serious foundation. Men vied with each other in

celebrating Diane's beauty, which, if we may judge from her portraits,

has been slightly exaggerated. She was a healthy, vigorous woman, and,

by dint of great pains, succeeded in retaining her beauty late into

life. It is said that even on the coldest mornings she would wash her

face with well water. Diane was a patroness of the arts. She entrusted

to Philibert de l'Orme the building of her chateau at Anet, and it was

for her that Jean Goujon executed his masterpiece, the statue of Diana,

now in the Louvre.

DIAPASON (Gr. [Greek: dia pason], through all), a term in music,

originally for an interval of an octave. The Greek is an abbreviation of

[Greek: he dia pason chordon symphonia], a consonance through all the

tones of the scale. In this sense it is only used now, loosely, for the

compass of an instrument or voice, or for a harmonious melody. The name

is given to the two foundation stops of an organ, the open and the

stopped diapason (see ORGAN), and to a standard of musical pitch, as in

the French _diapason normal_ (see PITCH, MUSICAL).

DIAPER (derived through the Fr, from the Gr. [Greek: dia], through, and

[Greek: aspros], white; the derivation from the town of Ypres,

"d'Ypres," in Belgium is unhistorical, as diapers were known for

centuries before its existence), the name given to a textile fabric,

formerly of a rich and costly nature with embroidered ornament, but now

of linen or cotton, with a simple woven pattern; and particularly

restricted to small napkins. In architecture, the term "diaper" is given

to any small pattern of a conventional nature repeated continuously and

uniformly over a surface; the designs may be purely geometrical, or

based on floral forms, and in early examples were regulated by the

process of their textile origin. Subsequently, similar patterns were

employed in the middle ages for the surface decoration of stone, as in

Westminster Abbey and Bayeux cathedral in the spandrils of the arcades

of the choir and nave; also in mural painting, stained glass, incised

brasses, encaustic tiles, &c. Probably in most cases the pattern was

copied, so far as the general design is concerned, from the tissues and

stuffs of Byzantine manufacture, which came over to Europe and were

highly prized as ecclesiastical vestments.

[Illustration: A B C]

In its textile use, the term diaper was originally applied to silk

patterns of a geometrical pattern; it is now almost exclusively used

for diamond patterns made from linen or cotton yarns. An illustration

of two patterns of this nature is shown in the figure. The floats of

the warp and the weft are mostly in three; indeed the patterns are

made from a base weave which is composed entirely of floats of this

number. It will be seen that both designs are formed of what may be

termed concentric figures--alternately black and white. Pattern B

differs from pattern A only in that more of these concentric figures

are used for the complete figure. If pattern B, which shows only one

unit, were extended, the effect would be similar to A, except for the

size of the unit. In A there are four complete units, and hence the

pattern appears more striking. Again, the repeating of B would cause

the four corner pieces to join and to form a diamond similar to the

one in the centre. The two diamonds in B would then alternate

diagonally to left and right. Special names are given to certain kinds

of diapers, e.g. "bird's-eye," "pheasant's-eye"; these terms indicate,

to a certain extent, the size of the complete diamond in the

cloth--the smaller kind taking the name "bird's-eye." The size of the

pattern on paper has little connexion with the size of the pattern in

the cloth, for it is clearly the number of threads and picks per inch

which determine the size of the pattern in the cloth from any given

design. Although A is larger than what is usually termed the

"bird's-eye" pattern, it is evident that it may be made to appear as

such, provided that the cloth is fine enough. These designs, although

adapted mostly for cloths such as nursery-diapers, for pinafores, &c.,

are sometimes used in the production of towels and table-cloths. In

the figure, the first pick in A is identical with the first pick in B,

and the part C shows how each interweaves with the twenty-four

threads.

DIAPHORETICS (from Gr. [Greek: diaphorein], to carry through), the name

given to those remedies which promote perspiration. In health there is

constantly taking place an exhalation of watery vapour from the skin, by

which not only are many of the effete products of nutrition eliminated,

but the body is kept cool. Under exertion or in a heated atmosphere this

natural function of the skin is increased, sweating more or less profuse

follows, and, evaporation going on rapidly over the whole surface,

little or no rise in the temperature of the body takes place. In many

forms of disease, such as fevers and inflammatory affections, the

action of the skin is arrested, and the surface of the body feels harsh

and dry, while the temperature is greatly elevated. The occurrence of

perspiration not unfrequently marks a crisis in such diseases, and is in

general regarded as a favourable event. In some chronic diseases, such

as diabetes and some cases of Bright's disease, the absence of

perspiration is a marked feature; while, on the other hand, in many

wasting diseases, such as phthisis, the action of the skin is increased,

and copious exhausting sweating occurs. Many means can be used to induce

perspiration, among the best known being baths, either in the form of

hot vapour or hot water baths, or in that part of the process of the

Turkish bath which consists in exposing the body to a dry and hot

atmosphere. Such measures, particularly if followed by the drinking of

hot liquids and the wrapping of the body in warm clothing, seldom fail

to excite copious perspiration. Numerous medicinal substances have the

same effect.

DIAPHRAGM (Gr. [Greek: diaphragma], a partition). The diaphragm or

midriff (Anglo-Saxon, _mid_, middle, _hrif_, belly) in human anatomy is

a large fibro-muscular partition between the cavities of the thorax and

abdomen; it is convex toward the thorax, concave toward the abdomen, and

consists of a central tendon and a muscular margin. The _central tendon_

(q, fig. 1) is trefoil in shape, its leaflets being right, left and

anterior; of these the right is the largest and the left the smallest.

The fleshy fibres rise, in front from the back of the xiphoid cartilage

of the sternum (d), laterally by six serrations, from the inner surfaces

of the lower six ribs, interdigitating with the transversalis,

posteriorly from the arcuate ligaments, of which there are five, a pair

of external, a pair of internal, and a single median one. The _external

arcuate ligament_ (h) stretches from the tip of the twelfth rib (b) to

the costal process of the first lumbar vertebra in front of the

quadratus lumborum muscle (o), the _internal_ and _middle_ are

continuations of the _crura_ which rise from the ventro-lateral aspects

of the bodies of the lumbar vertebrae, the right (e) coming from three,

the left (f) from two. On reaching the level of the twelfth thoracic

vertebra each crus spreads out into a fan-shaped mass of fibres, of

which the innermost join their fellows from the opposite crus, in front

of the aortic opening (k), to form the _middle arcuate ligament_; the

outer ones (g) arch in front of the psoas muscle (n) to the tip of the

costal process of the first lumbar vertebra to form the _internal

arcuate ligament_, while the intermediate ones pass to the central

tendon. There are three large openings in the diaphragm; the _aortic_

(k) is behind the middle arcuate ligament and transmits the aorta, the

vena azygos major, and the thoracic duct. In the right leaflet is an

opening (sometimes called the _hiatus quadratus_) for the inferior vena

cava and a branch of the right phrenic nerve (m), while in front and a

little to the left of the aortic opening is one for the oesophagus and

the two pneumogastric nerves (l), the left being in front and the right

behind. The fleshy fibres on each side of this opening act as a

sphincter. Passing between the xiphoid and costal origins in front are

the superior epigastric arteries, while the other terminal branches of

the internal mammaries, the musculo-phrenics, pass through between two

costal origins.

[Illustration: FIG. 1.--Abdominal Surface of the Diaphragm.]

Through the crura pass the splanchnic nerves, and in addition to these

the left crus is pierced by the vena azygos minor. The sympathetic

nerves usually enter the abdomen behind the internal arcuate ligaments.

The phrenic nerves, which are the main supply of the diaphragm, divide

before reaching the muscle and pierce it in a number of places to enter

its abdominal surface, but some of the lower intercostal nerves assist

in the supply. The last thoracic or subcostal nerves pass behind the

external arcuate ligament.

For the action of the diaphragm see RESPIRATORY SYSTEM.

_Embryology._--The diaphragm is at first developed in the neck region

of the embryo, and this accounts for the phrenic nerves, which supply

it, rising from the fourth and fifth cervical. From the mesoderm on

the caudal side of the pericardium is developed the _septum

transversum_, and in this the central tendon is formed. The fleshy

portion is developed on each side in two parts, an anterior or

sterno-costal which is derived from the longitudinal neck musculature,

probably the same layer from which the sternothyroid comes, and a

spinal part which is a derivative of the transversalis sheet of the

trunk. Between these two parts is at one time a gap, the _spino-costal

hiatus_, and this is obliterated by the growth of the

pleuro-peritoneal membrane, which may occasionally fail to close and

so may form the site of a phrenic hernia. With the growth of the body

and the development of the lungs the diaphragm shifts its position

until it becomes the septum between the thoracic and abdominal

cavities. (See A. Keith, "On the Development of the Diaphragm," _Jour.

of Anat. and Phys._ vol. 39.) A. Paterson has recorded cases in which

the left half of the diaphragm is wanting (_Proceedings_ of the

Anatomical Society of Gt. Britain, June 1900; _Jour. of Anat. and

Phys._ vol. 34), and occasionally deficiencies are found elsewhere,

especially in the sternal portion. For further details see Quain's

_Anatomy_, vol. i. (London, 1908).

_Comparative Anatomy._--A complete diaphragm, separating the thoracic

from the abdominal parts of the coelom, is characteristic of the

Mammalia; it usually has the human structure and relations except that

below the Anthropoids it is separated from the pericardium by the

azygous lobe of the lung. In some Mammals, e.g. Echidna and Phocoena,

it is entirely muscular. In the Cetacea it is remarkable for its

obliquity; its vertebral attachment is much nearer the tail than its

sternal or ventral one; this allows a much larger lung space in the

dorsal than in the ventral part of the thorax, and may be concerned

with the equipoise of the animal. (Otto Muller, "Untersuchungen uber

die Veranderung, welche die Respirationsorgane der Saugetiere durch

die Anpassung an das Leben im Wasser erlitten haben," _Jen. Zeitschr.

f. Naturwiss._, 1898, p. 93.) In the Ungulata only one crus is found

(Windle and Parsons, "Muscles of the Ungulata," _Proc. Zool. Soc._,

1903, p. 287). Below the Mammals incomplete partitions between the

pleural and peritoneal cavities are found in Chelonians, Crocodiles

and Birds, and also in Amphibians (Xenopus and Pipa). (F. G. P.)

DIARBEKR[1] (_Kara Amid_ or Black Amid; the Roman _Amida_), the chief

town of a vilayet of Asiatic Turkey, situated on a basaltic plateau on

the right bank of the Tigris, which here flows in a deep open valley.

The town is still surrounded by the masonry walls of black basalt which

give it the name of _Kara_ or Black Amid; they are well built and

imposing on the west facing the open country, but almost in ruins where

they overlook the river. A mass of gardens and orchards cover the slope

down to the river on the S.W., but there are no suburbs outside the

walls. The houses are rather crowded but only partially fill the walled

area. The population numbers 38,000, nearly half being Christian,

comprising Turks, Kurds, Arabs, Turkomans, Armenians, Chaldeans,

Jacobites and a few Greeks. The streets are 10 ft. to 15 ft. wide, badly

paved and dirty; the houses and shops are low, mostly of stone, and some

of stone and mud. The bazaar is a good one, and gold and silver filigree

work is made, peculiar in character and design. The cotton industry is

declining, but manufacture of silk is increasing. Fruit is good and

abundant as the rich volcanic soil is well watered from the town

springs. The size of the melons is specially famous. To the south, the

walls are some 40 ft. high, faced with large cut stone blocks of very

solid construction, with towers and square bastions rising to 500 ft.

There are four gates: on the north the Kharput gate, on the west the

Rum, on the south the Mardin, and on the east the Yeni Kapu or new

gate. A citadel enclosure stands at the N. E. corner and is now partly

in ruins, but the interior space is occupied by the government konak.

The summer climate in the confined space within the town is excessively

hot and unhealthy. Epidemics of typhus are not unknown, as well as

ophthalmia. The Diarbekr boil is like the "Aleppo button," lasting a

long time and leaving a deep scar. Winters are frequently severe but do

not last long. Snow sometimes lies, and ice is stored for summer use.

Scorpions noted for the virulence of their poison abound as well as

horse leeches in the tanks. The town is supplied with water both by

springs inside the town and by aqueducts from fountains at Ali Punar and

Hamervat. The principal exports are wool, mohair and copper ore, and

imports are cotton and woollen goods, indigo, coffee, sugar, petroleum,

&c.

The Great Mosque, Ulu Jami, formerly a Christian church, occupies the

site of a Sassanian palace and was built with materials from an older

palace, probably that of Tigranes II. The remains consist of the facades

of two palaces 400 ft. apart, each formed by a row of Corinthian columns

surmounted by an equal number of a Byzantine type. Kufic inscriptions

run across the fronts under the entablature. The court of the mosque is

entered by a gateway on which lions and other animals are sculptured.

The churches of greatest interest are those of SS. Cosmas and Damian

(Jacobite) and the church of St James (Greek). In the 19th century

Diarbekr was one of the largest and most flourishing cities of Asia, and

as a commercial centre it now stands at the meeting-point of several

important routes. It is at the head of the navigation of the Tigris,

which is traversed down stream by _keleks_ or rafts supported by

inflated skins. There is a good road to Aleppo and Alexandretta on the

Mediterranean, and to Samsun on the Black Sea by Kharput, Malatia and

Sivas. There are also routes to Mosul and Bitlis.

Diarbekr became a Roman colony in A.D. 230 under the name of Amida, and

received a Christian bishop in A.D. 325. It was enlarged and

strengthened by Constantius II., in whose reign it was taken after a

long siege by Shapur (Sapor) II., king of Persia. The historian Ammianus

Marcellinus, who took part in the defence, gives a detailed account of

it. In the later wars between the Persians and Romans it more than once

changed hands. Though ceded by Jovian to the Persians it again became

annexed to the Roman empire, and in the reign of Anastasius (A.D. 502)

was once more taken by the Persians, when 80,000 of its inhabitants were

slain. It was taken c. 638 by the Arabs, and afterwards passed into the

hands of the Seljuks and Persians, from whom it was finally captured by

Selim I. in 1515; and since that date it has remained under Ottoman

rule. About 2 m. below the town is a masonry bridge over the Tigris; the

older portion being probably Roman, and the western part, which bears a

Kufic inscription, being Arab.

The vilayet of Diarbekr extends south from Palu on the Euphrates to

Mardin and Nisibin on the edge of the Mesopotamian plain, and is divided

into three sanjaks--Arghana, Diarbekr and Mardin. The headwaters of the

main arm of the Tigris have their source in the vilayet.

Cereals, cotton, tobacco, rice and silk are produced, but most of the

fertile lands have been abandoned to semi-nomads, who raise large

quantities of live stock. The richest portion of the vilayet lies east

of the capital in the rolling plains watered by tributaries of the

Tigris. An exceptionally rich copper mine exists at Arghana Maden, but

it is very imperfectly worked; galena mineral oil and silicious sand are

also found. (C. W. W.; F. R. M.)
