following matters of geographical interest: the moon, the ebb and
flood, streams, climates, differences in the length of days and of
summer and winter in northern Norway, marvels of India, marvels of
Norway, snowshoes, Iceland, Greenland, whales, earthquakes and ice
fields in Iceland, flora and fauna of Greenland, volcanic phenomena in
Iceland and Sicily, subterranean fire in Iceland, the small extent of
habitable land in Greenland, climatic phenomena, the northern lights
and noises accompanying them, a cooler zone to the south of the hot
equatorial zone where it is summer during our winter. This synopsis is
based on portions of the _King’s Mirror_ as given in translation in
Nansen’s _In Northern Mists_, 1911.
Another Icelandic geographical description of the world, which
probably dates from our period, besides drawing on well-known earlier
authorities, also gives some idea of the Icelandic conception of
geography and furnishes details of the itinerary of a certain Abbot
Nicholas to Rome and the Holy Land. See above, p. 115, and also,
Nansen, _op. cit._, vol. ii, p. 237 and reference in note 1 regarding
the identity of the author of this work, probably Abbot Nikulás
Bergsson of Thverá (died 1159), though believed by Storm to be an
Abbot Nikulás of Thingeyre. See also K. Kålund, _En islandsk vejviser
for pilgrimme fra 12. århundrede_, in: Aarböger for Nordisk
Oldkyndighed og Historie, series 3, vol. iii, Copenhagen, 1913, pp.
51–105.
Footnote 460:
In addition to the general works discussed above, mention must be made
of a geographical treatise of minor importance dating from our period.
Book III of the _Tractatus excerptionum_, printed among the works of
Hugh of St. Victor in Migne, _Pat. lat._, vol. clxxvii, cols. 209–216,
is entitled _De situ terrarum_. This contains chapters on the three
parts of the earth, on Asia, Africa, and Europe, on mountains, rivers,
islands, and cities. Its attribution to Hugh of St. Victor is
extremely doubtful. See Santarem, _Essai_, vol. i, 1849, p. 66, note
2.
Footnote 461:
The monumental _Speculum mundi_ of the Dominican, Vincent of Beauvais,
which probably cannot have been written much before 1250, is divided
into three parts: _Speculum naturale_, _Speculum doctrinale_, and
_Speculum historiale_. There is no complete modern edition. Copies of
incunabula and of sixteenth- and seventeenth-century editions are not
rare. The work is a gigantic compilation drawn from a great multitude
of sources, all of which were carefully indicated by the diligent
compiler, together with additions by the compiler himself. Most novel
from the geographical point of view are the data on Asia taken from
Simon of St. Quentin and from John of Pian de Carpine, which are to be
found in _Speculum historiale_ (see above, pp. 269–270). _Speculum
naturale_ discusses the various features of the world in the order of
their creation. It is in the nature of a vast commentary on the first
chapter of Genesis. The following books are of especial geographical
significance: II, consisting of metaphysical and theological material
on the Creation; IV, dealing with the firmament, and the heavens; V,
with meteorology; VI, with the waters; VII, with the lands; XXXIII,
with regions habitable by man. The last is a typical cosmography, made
up largely of fragments from Isidore, in which chapters are devoted to
a discussion of the tripartite division of the earth, Asia and
Paradise, India and its marvels, Asia Minor, Europe, Greece, other
parts of Europe, Africa, the islands of the ocean which encircles the
earth, the islands of the Mediterranean Sea, the Cyclades, etc.
Footnote 462:
Most of Albertus Magnus’ (1193–1280) many and voluminous works, the
greatest repertory of Aristotelian science of the Christian Middle
Ages, constitute an immense paraphrase of and commentary on all the
writings of Aristotle that were available in the mid-thirteenth
century. Albert used many of the titles that were applied in the
period to Aristotle’s works and the customary division into books and
chapters. Of particular interest from the geographical point of view
are: _De caelo et mundo_ (Jammy edit., 1651, vol. ii); _Libri
meteorum_ (_ibid._, vol. ii); _De natura locorum_ (_ibid._, vol. v),
and _De proprietatibus elementorum_ (_ibid._, vol. v). Kretschmer,
_Phys. Erdk._, 1889, _passim_, and Werner, _Kosm. Wilhelm von
Conches_, 1873, _passim_, give a fairly satisfactory general idea of
the more important contributions of Albert to cosmology and physical
geography.
In the second book of the _De caelo et mundo_ Albert declares that the
earth is spherical because the particles which compose it are drawn
toward the center of the universe and, in striving to attain that
point, arrange themselves symmetrically in the form of a sphere. He
gives as proofs of the sphericity of the earth arguments that were
familiar to writers of antiquity (see above, p. 368, note 33).
In the _Libri meteorum_ (_Meteorology_) much material will be found on
the atmosphere, on the waters, and on earthquakes. Albert thought that
the winds are caused by an earthy humor raised by the sun (Werner,
_op. cit._, pp. 351–352; compare this theory with the theory of Seneca
and of William of Conches, pp. 171–172, above). He thought that the
areas of the earth’s surface covered by water are much more extensive
than those represented by land and that large rivers spring from great
cavities in the interior of the earth. These cavities, he maintained,
usually correspond in position to the major mountain ranges.
Points of physical geography are also treated at some length in the
_De proprietatibus elementorum_ (based upon the pseudo-Aristotelian
work of the same title): hot springs, volcanoes, tides, the Deluge,
the origin of mountains by earthquakes and by erosion. Albert
expresses vigorous opposition to the theory of the periodic rotation
of land and sea around the earth’s surface under astrological
influences (see above, pp. 14 and 83), but he believed, none the less,
that the heavenly bodies through their varying motions and
conjunctions may bring to bear powerful local changes in conditions of
dampness and dryness which in turn may even produce interchanges of
areas of land and sea. He refers to the discovery of the rudder of a
great ship when a certain well was dug in muddy ground as evidence of
gradual alterations in the relative level of land and sea (Kretschmer,
_op. cit._, p. 125).
In a great many respects the _De natura locorum_ is the most valuable
of Albert’s books from the geographical point of view. Kretschmer goes
so far as to declare that this work reveals to us in Albert the first
great geographer since antiquity (_ibid._, p. 139). Tractatus I
treats, among other matters, of latitudes and longitudes, of the
habitable and uninhabitable parts of the earth’s surface, and of
climates. Albert denies the older view that the equatorial regions are
totally uninhabitable on the ground that people were actually known to
dwell therein. Moreover, he was inclined to the belief that the
countries near the equator are more temperate and pleasant than those
nearer the tropics (see above, p. 164). Albert’s “climatic
observations in the _Liber de natura locorum_ have at all times
aroused undivided admiration, and we find in them the first attempt at
a comparative geography” (Kretschmer, _op. cit._, p. 139). This
applies more especially to his observations regarding the influences
of mountains, seas, woods, and other topographic features upon
climate. These would well repay careful comparison with the views of
William of Conches upon the same topics (see above, p. 178). Tractatus
III of the _De natura locorum_ is a “cosmographia,” or description of
the regions of the world, following the usual medieval scheme.
Footnote 463:
Bartholomew Anglicus, author of the _De proprietatibus rerum_,
“belonged probably to the circle of insular [British] clerics who were
ardently interested in experimental researches and in natural history;
of whom the encyclopedist Alexander Neckam was in a measure the
precursor, and of whom the Franciscan Roger Bacon was the most
illustrious representative” (C. V. Langlois, _La connaissance_, 1911,
p. 117). It has so far been impossible accurately to determine the
date of the _De proprietatibus rerum_, though it falls probably before
the middle of the thirteenth century (_ibid._, p. 118, note 2). This
work was a compilation from many different sources and was intended
for less educated readers. Book XI is devoted to the phenomena of the
air, XIII to the waters, XIV to the earth, and XV to a _mappamundi_,
or description of the various “provinces” of the earth in alphabetical
order. There is no modern edition. A summary of the contents will be
found in C. V. Langlois, _op. cit._, pp. 128–179, and a discussion of
Bartholomew’s geography is given by Thorndike, _Magic_, 1923, vol. ii,
p. 424–429. Extracts from an English translation of Berthelet, 1535,
are given in Steele, _Mediaeval Lore_, 1907 (under Bartholomew
Anglicus in the Bibliography). The future influence of the work was
very far-reaching, especially upon English literature of the
Elizabethan period (see Steele, _op. cit._, pp. 2–4; C. V. Langlois,
_op. cit._, pp. 126–127).
Footnote 464:
The Florentine Brunetto Latino died in 1295. He composed his great
_Livre du trésor_ in French during a period of exile in France between
1260 and 1266 (C. V. Langlois, _op. cit._, p. 328). This work met with
a wide success. It is divided into three parts, the first of which is
devoted to geography and cosmography. Much of the material here was
derived ultimately from Solinus. The _Trésor_ was edited by P.
Chabaille in 1863, but a definitive critical edition has not yet
appeared. For a criticism of Chabaille’s edition and for a summary of
the contents of the first part, see C. V. Langlois, _op. cit._, pp.
333–391.
Footnote 465:
Among these must be mentioned the following:
1. An unpublished encyclopedia by an otherwise unknown Arnold the
Saxon. This dates from between 1210 and 1250 and is preserved in a
manuscript in Erfurt. Rose’s edition, 1875, pp. 447–454, gives a
summary of the titles of chapters and prints the prologues of each
book. Some idea of the character of the work may be gained from
Stange’s dissertation and article, both listed in the Bibliography.
The first book, entitled _De caelo et mundo_, and the fourth, _De
virtute universali_, include data on physical geography, meteorology,
earthquakes, the sea, rivers, hot springs, and mineralogy (Stange,
_Arnoldus Saxo_, 1885, p. 18) derived in part from Aristotle’s
_Meteorology_ (_ibid._ and Rose, _op. cit._, p. 450). It has been
claimed that Arnold the Saxon’s encyclopedia was used by Vincent of
Beauvais, Albertus Magnus, and Bartholomew Anglicus, but this is
probably erroneous (see Thorndike, _Magic_, 1923, vol. ii, p. 430).
2. The _De natura rerum_ of Thomas of Cantimpré, in twenty books,
written between 1228 and 1244 and as yet unedited in a modern edition.
Thomas’ work was especially popular in Germany (see C. V. Langlois,
_op. cit._, p. 118, note 2; also Thorndike, _Magic_, 1923, vol. ii,
pp. 372–398).
3. A work of encyclopedic scope entitled _Summa philosophiae_, which
has erroneously been attributed to Robert Grosseteste but which cannot
possibly date from before 1250 and may be as late as 1270. It contains
chapters on meteorology, tides, and minerals. The full text is given
in Baur, _Philos. Werke Grossetestes_, 1912, pp. 275–643, with a
critical discussion of its authorship, pp. 126*-141*.
Footnote 466:
Roger Bacon, one of the most original thinkers of the entire medieval
period in matters of natural science, was the last of a series of
Englishmen who devoted themselves to these interests. In this group
may be counted Adelard of Bath and, at a much later date, Alexander
Neckam, Alfred of Sareshel, Daniel of Morley, and Robert Grosseteste
(see above, p. 407, note 94). For the last-named, whose teachings in
many particulars he adopted and elaborated upon, Bacon had the highest
admiration.
Born about 1210–1215, Roger Bacon became a Franciscan between 1245 and
1250. His more important works were completed before 1266 and were
condemned as heretical in 1278. He died in the last decade of the
century. See Bridges, _Life of Bacon_, 1914, and Thorndike, _Magic_,
1923, vol. ii, pp. 616–691.
From the geographical point of view beyond all question the most
important of Bacon’s writings was the _Opus majus_, which sets forth
his fundamental ideas in the realms of natural and physical science.
Bridges’ edition of this contains a full introduction and a detailed
analysis of the text, chapter by chapter. The geographical material
will be found in Part IV, on mathematical science. Distinctio ii of
Part IV (Bridges’ edit., vol. i, 1897, pp. 109–119) is devoted to the
subject of rays of light and emanations from the heavenly bodies and
to the problem of the sphericity of the universe. Elsewhere in Part IV
the influences of the heavenly rays upon the earth, especially in
respect to zones, tides, and the healthfulness of situations, are
brought out. Bacon here is largely indebted to Robert Grosseteste (see
above, pp. 163–165). These theories are also worked out in some detail
in the chapters of Part V (on optics) devoted to the multiplication of
species (Bridges’ edit., vol. ii, 1897, pp. 539–543; Werner, _Kosm.
Roger Baco_, 1879, pp. 597–599).
The last portion of Part IV (Bridges’ edit., vol. i, 1897, pp.
175–404), not divided into chapters, is a treatment of two broad
subjects:
1. The importance of mathematics in relation to theology. Under this
heading, among other points, there is given an explanation of how
mathematics aids us in acquiring knowledge of the heavens, of the
location of Paradise and of Hell, of sacred geography (that is of the
positions and physical conditions of places spoken of in Scripture),
of geometry (here the influence of mountains in reflecting the sun’s
rays is elucidated; see above, pp. 179–180; Werner, _op. cit._, p.
599; Duhem, _Système_, vol. iii, 1915, p. 418), and of numbers (here
are explained the size, distance, and relative magnitude of the
heavenly bodies in relation to the earth and to the heavenly spheres).
2. The influence of the heavens on things terrestrial (Bridges’ edit.,
vol. i, 1897, pp. 286–403). According to Bacon geographic conditions
are governed by astronomical and astrological forces. This part of the
_Opus majus_ shows first how the latter are effective in determining
the conditions of habitability on the earth’s surface; it closes with
a general description of the habitable earth (see especially Werner,
_op. cit._, p. 545, note 4, and pp. 546–550, on Bacon’s astrological
geography, and pp. 600–606, on Bacon’s regional geography). _Climata_
and the practical utility of knowledge of geography and of climates to
the missionary are discussed. The description of the habitable earth
is particularly full for Egypt, the Holy Land, India, Eastern Europe,
Central Asia, and Cathay. Much fresh material regarding the Mongols
and the Far East was derived from Bacon’s contemporaries, the
Franciscan travelers John of Pian de Carpine and William Rubruck (see
above, pp. 269–270). Bacon dismisses the geography of Western Europe
as too familiar to require special treatment.
Besides the _Opus majus_, Bacon’s _Communia naturalium_ and commentary
on the _Secretum secretorum_ include a few passages of interest to us.
In the former the finite character of the universe is explained
(Oxford edit., fasc., iv, pp. 369–373; see also, _Opus tertium_,
Brewer’s edit., pp. 140–141), together with some consideration of the
dimensions of heaven and of earth (Oxford edit., fasc. iv, pp.
414–418). In the latter (a book of miscellaneous precepts for the
guidance of human affairs, which was many times translated from the
Arabic during the Middle Ages and which was altered, augmented, and
edited by Bacon) there is material on astronomy, on the size and
sphericity of the earth, and on the relative extent of land and sea
(Oxford edit., fasc. v).
Footnote 467:
Dante treats incidentally of the traditional geography and astronomy
of his period in the _Convito_ and in numerous references in the
_Divine Comedy_. His sources were mainly Orosius, Isidore, Albertus
Magnus, and Brunetto Latino (see Moore, _Studies in Dante: Third
Series_, 1903, pp. 110–111). A most interesting and original
discussion of linguistic geography will be found in the _De vulgari
eloquentia_ (see Mori, _La geogr._, 1922, pp. 289–292; Andriani, _La
carta dialettologica_, 1923, pp. 255–263). The _Quaestio de aqua et
terra_, frequently ascribed to Dante, is of doubtful authenticity.
Moore, _Studies in Dante: Second Series_, 1899, pp. 303–374, Shadwell
in his edition of the _Quaestio de aqua et terra_, 1909, and Mori,
_op. cit._, p. 285, hold it to be a genuine work of the poet; Boffito,
_Intorno alla “Quaestio de aqua et terra,”_ Memoria I, 1902, believed
it to be spurious; serious objections to Boffito’s arguments, however,
were raised by V. Biagi in a review of the former’s work (Bollettino
della Società Dantesca, vol. x, Florence, 1903) with the “result that
Boffito himself appears to be less resolved to maintain his thesis in
his latest publication, _La “Quaestio de aqua et terra” di D. A., ed.
principe del 1508 riprod. in facsimile, etc._, Florence, 1905”
(Marinelli, _Scritti minori_, vol. i, [1908?], p. 196, note 3, p. 219,
note 1). See also Arnold Norlind: _Dante som geograf och medeltidens
behandling av frågan on vatten och land_, in: Ymer: Tidskrift utgiven

Footnote 471:
The genuineness of the _Ligurinus_, which had long been suspected of
being an imposture, was established after 1870 by two scholars working
simultaneously and independently, Pannenborg and Gaston Paris.
Pannenborg, who at first thought that the author of this poem was an
Italian, was subsequently converted to the opinion that he was a
German by the arguments of Paris. In 1883 Pannenborg definitely
established the thesis that the _Ligurinus_ was the work of Gunther of
Pairis. See Pannenborg, _Über den Ligurinus_, 1871; the same,
_Magister Guntherus_, 1873; the same, _Der Verfasser_, 1884; Gaston

The discovery of Iceland is also described in a Latin work written by
“Theodricus monachus,” probably toward the close of the twelfth

The fundamental work on the Romance of Alexander during our period is

Footnote 498:
The _Historia de praeliis_, for instance, the tenth-century work of
Leo Archipresbyter (see above, p. 381, note 26), was the text from
which Frutolf of Michaelsberg derived the version of the Romance of
Alexander which he inserted in his chronicle and which thus found its
way to the chronicle of Otto of Freising (Meyer, _op. cit._, vol. ii,
p. 39). That the chronicle from which Otto drew was by Frutolf and not
by Ekkehard of Aura was shown by Bresslau, _Die Chroniken_, 1895.

This probably dates from the beginning of the twelfth century (Meyer,
_op. cit._, vol. ii, p. 49).

Footnote 504:
Meyer, _loc. cit._, has worked out the probable authorship and
derivation of the various parts of the poem. He divides the work as a
whole into four consecutive sections or “branches.” Of these the
oldest is the third in order and is by Lambert li Tors; this branch
contains those parts of the Romance which are concerned with
Alexander’s adventures in the heart of Asia and in India; in fact
those parts of the work which contain the majority of the elements of
geographic interest. To this third branch, the first, second, and
fourth were added at a later date. These were the work of Alexandre de
Bernai and Pierre de St. Cloud. There are also a number of
interpolations into the body of the poem which may not be attributed
to any of the three writers named.
Footnote 505:
This poem was entitled _Le Roman de toute chevalerie_. Meyer (_op.
cit._, vol. ii, p. 275) knew of four manuscripts. In one of these, in
Paris, the _Roman_ is ascribed to Thomas of Kent, and in a manuscript
in Cambridge it is attributed to Eustace of Kent—Meyer holding that
the latter is correct. There is much of geographical interest in the
poem. The following are some of the chapter headings of parts dealing
with material of geographic significance (from a manuscript in Durham,
Library of the Chapter of Durham, C. iv, 27b, as cited by Meyer, _op.
cit._, vol. i, pp. 177–190).

As the manuscript of this book is about to go to press there has come
to the writer’s attention the brief note by Paul Borchardt,
_L’itinéraire de Rabbi Benjamin de Tudèle_, 1924. Borchardt writes (p.
31): “En différents travaux j’ai prouvé que le célèbre Rabbi Benjamin
ne mérite pas le reproche d’inexactitude, même en ce qui concerne la
route de Chine.... J’espère prouver par ce qui suit que R. Benjamin
mérite comme Marco Polo le nom d’un homme digne de foi.” References
are given in footnote 1, p. 31, of Borchardt’s note to other studies
by Borchardt relating to Benjamin. Unfortunately the present writer
has been unable to consult these. The references follow as given by
Borchardt: “Conférence de la Soc. d’Anthrop. de Munich: _Reiseweg des

In addition to the _Mirabilia_, there was written, probably in the

the _Mirabilia_, although it deals with the same subject. The author
may have been an Englishman. See James, _Magister Gregorius_, 1917

Miller’s _Mappaemundi_, vol. i, 1895, deals with the Beatus maps and
is accompanied by a colored reproduction of the St. Sever Beatus map
(our Fig. 2, p. 69). Vol. ii, 1895, is an atlas of photographic
reproductions of the Beatus and other maps of the world of the period.
Vol. iii, 1895, contains explanatory text on the more important
earlier maps, together with photographs and cuts. Vol. iv, 1896, and
vol. v, 1896, are devoted to the Hereford and Ebstorf maps of the
world from after our period, and vol. vi, 1898, to attempts at the
reconstruction of lost _mappaemundi_. A word of caution is perhaps
necessary against too ready acceptance of all of Miller’s theories
regarding the connections between maps and the influence of one type
upon others. See above, p. 377, note 167, and below, p. 458, note 17.

included, described by Santarem.” See Santarem, _Essai_, vol. iii,
1852, pp. 499–505. Beazley (_Dawn_, vol. ii, 1901, p. 626), following
Miller, also ascribes these maps to a manuscript of the _Magna de
naturis philosophia_. The manuscript in question, however, is of no
other work than William of Conches’ _De philosophia mundi_, which
Santarem (_op. cit._, pp. 499–500) ascribed wrongly to William of
Hirschau (see above, p. 398, note 28). No manuscripts or copies of the
_Magna de naturis philosophia_ are extant, and Poole believes that if
such a work ever existed it has been wrongly attributed to William of
Conches (Poole, _Illustrations_, 1920, pp. 306–310).

Footnote 594:
Though Comestor here denies the teachings of Plato in regard to the
existence of matter prior to the “Creation,” he adopted a traditional
medieval view based on the _Timaeus_ of Plato and given expression by
Augustine: that God created time and the universe simultaneously (see
above, p. 52). How these two conceptions were reconciled is shown by
Daniel of Morley where he writes: “Primus mundus est in eternitate
figuratus, secundus cum tempore creatus, tercius in tempore formatus”
(_De philosophia_, Sudhoff’s edit., p. 8). (For Daniel of Morley’s
views on hyle see Singer, _Daniel of Morley_, 1920, p. 267.)
Essentially the same Platonic doctrine was shared by Hugh of Amiens,
archbishop of Rouen, who wrote in his _Tractatio in hexaemeron_ that
God precedes the world by eternity, not by time (Migne, _Pat. lat._,
vol. cxcii, col. 1249). The _De imagine mundi_ (II, 1) applied the
term _aevum_ to God alone; _tempora aeterna_, beginning before the
world and continuing with and after it, to the _architypus mundus_ and
to the angels; and _tempus_ to the world (Robbins, _Hexaemeral Lit._,
1912, p. 7, note 1).
Footnote 595:
_De phil. mundi_, I, 21.
Footnote 596:
Bede and Hugh of St. Victor also held that the elements were thus
segregated at the moment they were called into existence by God
(Zöckler, _op. cit._, vol. i, 1877, pp. 248, 401).
William of Conches argues specifically against the Aristotelian
doctrine of a fifth element of which the heavenly bodies are composed
(_Dragmaticon philosophiae_, III, 80–83, cited by Schneider,
_Abendländische Spekulation_, 1915, p. 40, note 1). Duhem (_Système_,
vol. iii, 1915, pp. 105, 194) saw in William’s _De philosophia mundi_
what seemed to be a remarkable analogy between the ideas there
expressed and those expressed by Aristotle in the fourth book of his
_Physics_. Schneider (_op. cit._, pp. 40–42) points out that Duhem,
through failure to take into account the passage in the _Dragmaticon_
to which we have just referred, was led to think that William was
actually a believer in the main theories set forth in the _Physics_.
On the contrary, in referring to the elements in the _Dragmaticon_
William merely adopted the traditional Platonic doctrine, and he went
on to explain Aristotle’s theory of the fifth element and vigorously
to denounce it. Though this shows that William may not have agreed
with Aristotle in essentials, it would seem to be, nevertheless, an
argument in favor of the existence of an Aristotelian trend of thought
in William’s time. See above, p. 401, note 58.
Footnote 597:
Though William denied the possibility of chaos preëxisting the
“Creation,” he was none the less accused of heresy by Walter, prior of
St. Victor in Paris during the last part of twelfth century, because
of his failure to make it clear that God created everything out of
nothing. William’s atomic theories suggest the possibility of belief
in his mind that matter in the form of atoms had coexisted with God
and that at the so-called “Creation” God had merely organized and
arranged these atoms. See Hauréau, _Singularités_, 1861, p. 258;
Poole, _Illustrations_, 1920, pp. 300–301.
Footnote 598:
_De sex d. op._, p. 62.
Footnote 599:
See above, pp. 15–16. Belief in the World Soul (_anima mundi_) was a
doctrine of Platonism. Theodoric of Chartres (_De sex d. op._, pp.
60–62), Bernard Sylvester (_De mundi univ._, _passim_), and William of
Conches (see Poole, _op. cit._, p. 151) shared it with Peter Abelard
(Hauréau, _op. cit._, p. 253). The two latter, like Theodoric,
identified this mysterious unifying conscious spirit of all things
with the Holy Ghost and maintained that belief in the World Soul was
not inconsistent with the Christian teaching that each individual has
a personal soul of his own. The personal soul in some way was thought
to be merged with and to form a portion of the World Soul. The theory
of the World Soul, however, could not be purged of an heretical taint.
At the very beginning of our period Manegold argued as vigorously
against it (_Contra Wolfelmum Coloniensem opusculum_, 1–3) as he
argued against the possibility of antipodeans (see above, p. 161). It
was also severely condemned by other defenders of more old-fashioned
and orthodox beliefs. Peter Comestor says, for example: “Hunc locum
male intellexit Plato, dictum hoc putans de anima mundi” (_Hist.
schol._, Gen. 1, 2), and Peter Lombard’s whole treatment of the
question of the Trinity in the _Sententiae_ (II, 17) precludes the
possibility of a World Soul. Peter Lombard specifically states that
the soul of man is not of the same substance as the soul of God.
Footnote 600:
Theodoric adduced various reasons for the rotary motion of the heavens
and gave explanations of this phenomenon which so closely resembled
the arguments given by Aristotle in his _De caelo_ (I, 8; II, 3),
_Physics_ (IV, 4), and _De motu animalium_ (II, 698b) (see above, p.
370, note 42) that Duhem was led by them to the opinion that the
Chartres scholar must have had direct access to Arabic translations of
versions of Aristotle. See above, p. 154, and p. 401, notes 57, 58.

19*-24*—especially p. 23*—93*-95*, 101–106). Robert Grosseteste’s
pupil, Roger Bacon, “believed that he was in a position to demonstrate
by philosophical proofs that the world had a beginning; and besides he
maintained that Aristotle never maintained a contrary doctrine”
(Duhem, _op. cit._, vol. v, p. 402). Albertus Magnus, on the other
hand, did not categorically deny the truth of the Aristotelian
teaching, “but rather treated it as a theory that must be accepted
from the philosophical point of view but rejected from the
theological” (Zöckler, _op. cit._, vol. i, p. 439). Bacon discussed
this matter in an unpublished work now preserved in the Bibliothèque
Municipale at Amiens, MS. no. 406, fol. 69, col. a; see Duhem, _op.

There are marked analogies between the theory of the microcosm as
expounded by Herrad and by Hildegard of Bingen. Singer believes that
“the theory, in the form in which these writers present it, reached
the upper Rhineland somewhere about the middle or latter half of the
twelfth century” (Singer, _Visions of Saint Hildegard_, 1917, p. 20).

spurious (see above, p. 396, note 8), omits consideration of these
works in this connection.

Translation of Al-Farghānī’s _Astronomy_ by John of Seville (or
Johannes Hispanensis, or John of Luna), Nuremberg edit., diff. iv,
fol. 4ro. In the _De sphaera_, _loc. cit._, John of Holywood stated
that Ptolemy and all philosophers had declared that six signs and the
middle of the heaven (_medietas caeli_)—by which he probably meant the
celestial equator—were visible from any place whatsoever to which a
man might go on the surface of the earth. If the earth were not at the
center of the universe it would be impossible, he argued, to see the
_medietas caeli_ from those parts of the earth nearest the firmament:
“aliquis existens in illa parte superficiei terrae quae magis
accederet ad firmamentum non videret caeli medietatem.”
[Illustration:
Fig. 10—Diagram to illustrate John of Holywood’s reasoning that the
earth is in the center of the universe.
]
Figure 10 illustrates what appears to have been John’s line of
reasoning as well as the flaws in it. With the earth in position I,
not in the center of the universe, the celestial equator (_E-E′_) is
invisible from all points between _x_ and _y_ through _N_ (the north
pole), _x_ and _y_ being points at which tangents _E-x_ and _E′-y_
touch the earth’s surface. If the earth is in the center of the
universe and the sphere of the universe is incomparably great in
relation to the size of the earth—something which John believed to be
true (see above, p. 155)—the area between _x′_ and _y′_ will be
reduced to a very small area around _N′_. John seems to have assumed
that the universe is large enough to make this area negligible. Such
an area must exist, nevertheless, with all but an infinitely great
celestial sphere. But if the universe were of infinite dimensions,
John’s entire argument based on the invisibility of _E-E′_ from an
earth not in the center would fall to the ground, for all points may
be deemed the center of an infinite universe. See also below, p. 426,
note 118.
Ptolemy’s _Almagest_, I, 4, contains an argument aimed to demonstrate
why the earth must be at the center of the universe. John of
Holywood’s reasoning is a confused attempt to condense the argument of
Ptolemy into a short space.

Footnote 660:
_Liber div. op._, pars I, visio II, in: Migne, _Pat. lat._, vol.
cxcvii, cols. 751–755, 759–760. In a previous vision referred to in
the passage just cited and described in _Scivias_, I, visio III
(Migne, _op. cit._, col. 405), Hildegard saw the universe as an egg,
in which the earth appeared as follows: “Et in medio istorum
elementorum quidam arenosus globus plurimae magnitudinis erat; quem
eadem elementa ita circumdederant, quod nec hac nec illac dilabi
poterat. Sed dum interdum eadem elementa cum praedictis flatibus se
invicem concuterent, eumdem globum sua fortitudine aliquantulum
moveri. Et vidi inter aquilonem et orientem velut maximum montem, qui
versus aquilonem multas tenebras et versus orientem multam lucem
continebat; ita tamen quod nec lux illa ad tenebras, nec tenebrae ad
lucem pertingere poterant.”
Singer in his _Visions of Saint Hildegard_, 1917, pp. 22–30, discusses
Hildegard’s theories of the structure of the material universe as
revealed in the records of her visions. Particularly striking are the
colored illustrations taken from miniatures in manuscripts of her
works. Singer asserts (p. 22) that “the concentric structure of the
universe is a commonplace of mediaeval science, and is encountered,
for instance, in the works of Bede, Isidore, Alexander of Neckam,
Roger Bacon, Albertus Magnus, and Dante. To all these writers,
however, the universe is spherical. The egg-shape is peculiar to
Hildegard. Many of the _Mappaemundi_ of the Beatus and other types
exhibit the _surface_ of the habitable earth itself as oval, and it
was from such charts that Hildegard probably gained her conception of
an oval universe. In her method of orientation also she follows these
maps, placing east at the top of the page where we are accustomed to
place the north.” This statement would seem to be misleading if it
means that the comparison of the universe with an egg is peculiar to
Hildegard. As is shown by the texts cited above, p. 151, and below,
note 100, _ad fin._, this comparison was a frequent one throughout our
period. It does not, however, necessarily imply belief that the
universe is shaped like an egg, but merely that its concentric
structure corresponds with that of the egg. Furthermore, in the
opinion of the present writer, the fact that the Beatus and other maps
of the period show the surface of the habitable earth as an oval or
rectangle should not necessarily be taken as meaning that the
draftsmen of the maps believed that the earth was oval or rectangular.
The maps were highly conventionalized, and their shape was often
determined by the shape of the page upon which they were drawn. On the
other hand, Hildegard in her Scivias unquestionably meant to describe
an egg-shaped universe. Otherwise she would not have been so careful
to point out at the opening of the _Liber divinorum operum_ that in
the earlier vision described in _Scivias_ the universe had appeared as
an egg whereas in the vision she was about to describe it appeared as
a wheel.
Footnote 661:
“In medio quoque aeris terra posita est, ita scilicet ut aer aequali
mensura super terram, ac sub terra, et in utraque partes terrae sit”
(_Liber div. op._, pars I, visio IV, cap. 63).
Doubts have been thrown on the authenticity of the _Causae et curae_
as a work of Hildegard (see above, p. 396, note 8). The three passages
quoted in this and the two preceding notes show that in both phrasing
and substance the passage from the _Causae et curae_ bears marked
resemblances to the passages from the two other known works of
Hildegard, even though there is inconsistency in regard to the central
issue relating to the position of the earth. If the _Causae et curae_
were not written by Hildegard, it was assuredly the work of someone
thoroughly familiar with her writings.

Footnote 667:
See Alexander Neckam, _De nat. rer._, II, 14, where much the same
argument is given. Neckam adds that the roundness of drops of dew is
proof of the inherent tendency of water to assume a spherical shape.
Footnote 668:
The text upon which this accusation is based is from _Otia imper._,
II, 2, where Gervase says: “Nos tamen assignantes orbis divisionem
distributioni filiorum Noë, a quibus summa totius orbis coepit
partitio, orbem totius terrae Oceani limbo circumseptum et quadratura
statuimus secundum Pauli Orosii sententiam, eiusque tres partes Asiam,
Europam et Africam nominamus.” This was interpreted by Daunou
(_Discours_, 1824, p. 120)—who was followed by Santarem (_Essai_, vol.
i, 1848, p. 107), C. B. Jourdain (_Infl. d’ Arist._, 1861, pp. 19–20),
and others—as implying that Gervase believed the earth to be square.
On the other hand, Lecoy de La Marche rallied to the defense of
Gervase (_Connaiss. géogr._, 1884, p. 208). He argued that the passage
should be rendered thus: “Nous calculons, nous pensons, que le monde
terrestre est entouré et encadré (_quadratum_) par une ceinture de
mers” and that elsewhere Gervase asserts definitely that the earth is
a sphere: “Forma eius (terrae) rotunda est ad modum pilae” (_Otia
imper._, vol. i, p. 885). As a matter of fact Gervase was speaking of
the universe and not of the earth when he made this comparison with a
ball, and Lecoy de La Marche would have been more correct if he had
inserted _mundi_ after _eius_ instead of _terrae_. It seems,
nevertheless, that we are justified in rejecting the text first quoted
as furnishing any sure evidence that Gervase believed the earth to be
square, especially since he also adopted the old comparison of the
universe to an egg (_Otia imper._, _loc. cit._) with which it would
have been difficult, though not impossible, to reconcile a theory of a
square earth. Gervase, however, had an uncritical mind. His work was
in large measure one of compilation from the writings of others, and
it would not be surprising to find contradictory statements in it.
Quite as contradictory passages on the same subject occur in Isidore
and in most medieval writings of a similar encyclopedic character. See
above, p. 54. Lecoy de La Marche, it would seem, tried to do the
impossible when he attempted to show that Gervase had clear and
consistent ideas of a scientific nature.
There is no question, however, but that belief in the sphericity of
the earth was well grounded in the consciousness of many Western
Europeans of the late twelfth century. Other evidence of this beside
that already cited is furnished by the fact that in an ecstasy Alpis
(or Alpäis) of Cudot, of the diocese of Sens, was said to have seen
the entire world in the form of a globe, compact and united. The sun
was larger than the earth; and the latter was suspended in the midst
of the air like an egg surrounded by water on all sides (_Histoire
littéraire de la France_, vol. ix, 1750, p. 155). This vision was much
like those of Hildegard of Bingen; see above, p, 423, note 92.
Footnote 669:
_Causae et curae_, II; Kaiser’s edit., p. 49, quoted above, p. 423,
note 91. The fact that Hildegard here states that if the earth were in
the middle of the firmament it would have to be larger or else it
would fall, would seem to necessitate belief in a flat earth
contiguous with the firmament. The passage from _Causae et curae_, I,
Kaiser’s edit., p. 23, translated above, pp. 183–184, would also seem
to require the same belief.

text the _Image du monde_ here corresponds, borrowed from Ptolemy
certain details in regard to the relative sizes of sun, earth,
planets, and stars. The sun is by far the largest body in the
universe, 166 and a fraction times larger than the earth. Next after
the sun rank fifteen of the largest fixed stars; Jupiter ranks in the
third place, Saturn in the fourth, the remainder of the fixed stars in
the fifth, Mars in the sixth, the earth in the seventh, Venus in the
eighth, the moon in the ninth, and Mercury in the tenth. See Ptolemy,
_Almagest_, V, 16.

Footnote 686:
“Item si intelligatur superficies plana super centrum terrae dividens
eam in duo aequalia, et per consequens ipsum firmamentum, oculus
igitur existens in centro terrae videret medietatem firmamenti;
idemque existens in superficie terrae videret eandem medietatem. Ex
his colligitur quod insensibilis est quantitas terrae quae est a
superficie ad centrum et per consequens quantitas totius terrae
insensibilis est respectu firmamenti” (_loc. cit._).
John of Holywood’s argument is here closely related to that employed
by him to prove that the earth must be in the center of the universe
as set forth above, p. 422, note 81. It would seem probable that by
“an eye stationed in the center of the earth” he means an eye on a
line between the center of the earth and the _medietas firmamenti_,
and by “the same (eye) stationed on the surface of the earth” he means
on the surface at a point where a line at right angles to the line
from the center of the earth to the _medietas firmamenti_ cuts the
surface of the earth. Referring, then, to Figure 10, p. 422, above,
let us assume that line _E-E′_ represents the plane through the
_medietas firmamenti_ and the center of the earth (_C_). When the
earth is at the center of the universe line _C-N′_ will represent the
line drawn at right angles to this plane. With a universe of infinite
dimensions obviously _N′-E_ and _N′-E′_ would be parallel to _E-E′_,
and the _medietas firmamenti_ would be visible from _N′_. John assumes
that the universe is so large in relation to the earth that the area
around _N′_ whence _E-E′_ would be invisible is negligible.

1924, pp. 62–64): “Hinc vero per Amphitritis sinus ab Athlante Libico
Strixisque inflexu per littora Gaditana per confinia Thiles proprie
Temiscirios campos e vicino portibus Caspiis usque ad Caucason et
Ethiopici Gangis effluxus.” In another passage of the same work quoted
by Haskins (_op. cit._, p. 64) Hermann indicates that in the latitude
of Lisbon and Toledo eight equal land stages are the equivalent of 4°
of longitude, that the width of Amphitrite is 44°, or the equivalent
of eighty-eight equal land stages, and that there is an opinion that
paradise lies beyond this ocean. “... spatium ... dierum 44 que
secundum quod ratio tribuit est dimidia latitudo Amphitritis, tota
(totam) videlicet itineris terrestris equabilis dierum fere 88. Tantum
ergo spatii vel etiam aliquanto plus que ratio hucusque transnatari
prohibuit nondum audivimus nisi forte illa quam (que) exposuimus. In
ea tamen parte non modica est opinio eam esse regionem quam paradisum
vocant, cuius indicio sunt signa tam ab oriente quam ab occidente.” In
this same passage Hermann states that Toledo is 62° west of Arin (see
above, p. 86). One would therefore expect the width of Amphitrite to
be 44° in order to bring to 90° the total distance from Arin to the
prime meridian in the midst of Amphitrite (Haskins, _op. cit._, p. 64,
note 202).

THE ATMOSPHERE
Footnote 730:
Those parts of the _Dragmaticon philosophiae_ and of the _De
philosophia mundi_ which deal with meteorology are conveniently
available in Hellmann, _Denkmäler_, 1904, pp. 42–54, 69–75. See also

Footnote 734:
These five regions were: (1) the celestial region, or sphere of the
fixed stars; (2) the region of ether, which reaches from the sphere of
the fixed stars down to that of the moon; (3) the upper air, clear and
lucid; (4) the lower air, turbid and cloudy; and (5) the earth. (_De
phil. mundi_, I, 16–21). See Werner, _loc. cit._, for discussion of
these ideas, of their derivation from Plato’s _Timaeus_ and from later
Platonists, and of the “demons” associated with each of the five
regions.
Footnote 735:
_De phil. mundi_, IV, 5: III, 5, 6.
Footnote 736:
Robert Grosseteste believed that if you take into account the
theoretical principles of the “pyramids” of rays alone (see above, pp.
163–164), mountain heights should be hotter than valleys because the
pyramids striking the crests of mountains are shorter than those
striking the floors of valleys (_De natura locorum_, Baur’s edit., p.
66). In other words, mountain summits theoretically ought to be warmer
because they are nearer the sun. In the _De natura locorum_ Robert
explains that accidental circumstances frequently cause a reversal of
these conditions in such a way that the heights may be dominated by
cold. Among these accidental circumstances are the winds and also the
fact that peaks rise to the “middle space of the air or of the sphere
where there is the greatest cold (medium interstitium aeris vel
sphaerae, ubi est maxima frigiditas).”

“Triplex est universa dimensio, in longum, latum, et altum. Quoniam

terram esse necesse est. Eius pars quedam a terra in altum crescit,
alia vero super terram in altum elevatur tocius fomentum hic spiritus
terreni vapores pinguedine crassus, sine quo nulla huius geniture vita
per aliquot horarum spacia possibilis. Hic autem vapor, ut per
altitudinem Olimpi concipit Aristotiles, a terre superficie non plus
quam .xvi. stadiis exaltatur. Hic ergo terminus videtur in altum omnis
nostre habitabilis. Videtur fortasse huius altitudinis mensura sumi
posse vel per arcum yris que secundum Ipparci descriptionem ab ipsis
nubibus usque in superficiem terre perveniat. Sed quoniam nec ipsa
descriptio constans nec ipsius arcus ad semicirculum habitudo,
propterea nos id cuilibet probandum relinquimus” (_Liber de
essentiis_, text from Haskins, _Studies_, 1924, p. 62, where variant
readings from different manuscripts are given). Haskins points out
that Aristotle (_Meteor._, I, 13) omits Olympus from his list of the
highest mountains.

Footnote 743:
The origin of this story has not been traced by the present writer. It
would certainly seem to be based on some actual knowledge of the
physiological effects of lower air pressure at great heights.
According to Benini (_Origine del Monte del Purgatorio_, 1917, p.
1085) Dante (_Purgatorio_, XXVIII, 103–112; see also _Inferno_, IV,
26–28, 149–150) held that the Mount of Purgatory reaches above the
lower levels of the atmosphere, which are corrupted by the earth and
where winds, clouds, rain, hail, and rainbows are to be found, into a
realm of motionless air. The very summit of the mountain where the
Terrestrial Paradise is situated is in a belt of air which moves from
east to west with the motion of the ninth sphere.

Of the water drawn up by the sun, the lighter or “more liquid”

fires. The coarser portions fell back to the earth. A blood rain was
caused by great heat.

William of Conches follows Theodoric in this explanation of snow and
hail (_De phil. mundi_, III, 4, 8, 9). In the epic poem, _Philippis_
(IX, 672–682), of William the Breton there is a remarkable description
of a nocturnal fog lying over the humid and fertile ground near Lille,
so thick that a rider could scarcely discern the ears of his horse in
front of him. William attributed the fog to damp vapors rising from
beneath the muddy surface of the plain rather than to a more probable
cause: the cooling and condensation of water vapor in the lower strata
of the atmosphere as a result of active radiation from the earth’s
surface.

A characteristic story of this sort is related in the _Gesta regis
Ricardi_, falsely ascribed to Benedict of Peterborough. Here we are
told that a huge black dragon raises waterspouts in the Gulf of
Satalia on the south coast of Asia Minor. The author adds, however:
“Quidem autem dicunt quod hoc non est draco sed sol qui attrahit aquas
maris ad se, quod plus verum videtur” (_Gesta regis Ricardi_, vol. ii,
p. 197). The author is also skeptical towards a fantastic story of how
storms are produced in the same gulf by the rising to the surface of
the head of an abortive child that had been thrown into its waters
(_ibid._, p. 196).

Alexander Neckam makes Boreas a bringer of hail and Auster a rainy
wind (_De laud. div. sap._, II, 85–92).
Bernard Sylvester writes:
“Obriguit Boreas, maduit Notus, Auster et Eurus:
Hic tempestates, ille serena facit.”
—_De mundi univ._, p. 19.
Classical tradition, however, was apparently uniform in conceiving of
Notus and Auster as the same. See table in Gilbert, _op. cit._, pp.
550–551. William of Conches describes Boreas as a dry, as well as
cold, wind “because it drives the clouds before it toward the mid
region of the earth.” But also, because of the very fact that it does
so drive the clouds before it, it is a producer of rain along the
borders of the torrid zone. “Siccus vero, quia nubes de hoc angulo
terrae ad medium fugat, estque pluviosus juxta fines torridae zonae”
(_De phil. mundi_, III, 15).

See also Giraldus Cambrensis, _Top. Hiber._, I, 3, on Zephyr and
Eurus, and I, 6, on Corus, the violent northwester which uproots or
bends over trees in the west of Ireland. Corus was the favoring wind
for voyagers from England to France, according to Willibald, an eighth
century ecclesiastic, associate of Boniface, in his _Vita Bonifatii_,
5 (Migne, _Pat. lat._, vol. lxxxix, col. 613). Alexander Neckam (_loc.
cit._) and Bernard Sylvester (_loc. cit._) make Eurus a stormy wind.
Neckam says that it disturbs the waters and is unwelcome to travelers;
Zephyr, on the other hand, spreads the fields with flowers.

William of Conches went on to explain in this connection (_De phil.

observers had attributed to the presence of waters. “What do we see up
there, dense and the color of water? It is not fire, for if the air is
invisible because of its great rarity (_subtilitas_), so also must
fire be invisible, fire which is so much more rare than air.
Furthermore, it is not the color of fire.” William asserted that you
see nothing at all and that the impression of seeing water is an
optical illusion. Unless some other color interposes, a ray of light
on entering the eye takes the color of water from the aqueous humor
contained in the eye.

_Expos. in psalmos_, ad Ps. cxxxv, 6, in: Migne, _op. cit._, vol.
cxciv, col. 901). “Quod autem terra super aquas fundata esse dicitur,
nostram scientiam excedit. Mihi autem non videtur mirabilius, terram
super aquas esse fundatam, quam aquas, quae eiusdem ponderis sunt,
super terras in aere volare” (Bruno Astensis, _Expos. in psalmos_,
cxxxv, in: Migne, _op. cit._, vol. clxiv, col. 1194). Bruno adds an
allegorical explanation (_loc. cit._): “Possumus autem per terram
Ecclesiam intelligere quae super multos populos fundata est, qui per
aquas significantur, etc.”
Footnote 842:
“Movebitur aliquis super hoc quod dicit propheta ‘Dominum firmasse
terram super aquas.’ Ex hoc enim videbitur haberi posse aquas esse
inferiores terra, cum tamen Alfraganus dicat, unam esse sphaeram
aquarum et terrae. Sancti igitur expositores referunt illud prophetae
ad cotidianum usum loquendi quo dici solet Parisius fundatam esse
super Secanam. Rei tamen veritas est, quod paradisus terrestris
superior est aquis, cum etiam lunari globo superior sit” (_De nat.

aqua in concavitates terrae recessit et apparuit superficies terrae
arida et separata. Estque terra cum aquis in se contentis sicut
sphaera terrae solum” (_De sphaera_, Baur’s edit., p. 12). Günther,
_Studien_, vol. iii (?), 1879, p. 160, interpreted the last sentence
to indicate that Robert believed that waters were contained in the
interior of the earth and that it was to these waters that he here
refers. Though this is possible, it is more likely from the context
that the words “aquis in se contentis” are a reference to the seas
(Stegmann, _Anschauungen_, 1913, p. 15).

113–114.
The fact that the waters do not completely cover the lands also had
puzzled the Moslems, who anticipated Robert Grosseteste in ascribing
this apparent reversal of the normal operation of the laws of nature
to God’s wish to preserve a dry area whereon man and animals might
thrive. Averroës had given a more proximate cause, maintaining that
the stars are more numerous in the northern hemisphere than in the
southern and that through their attraction of the land, as well as
through the evaporative power of their heat and of that of the sun,
the lands were uncovered. On the theory of eccentric spheres of earth
and water see Kretschmer, _Phys. Erdk._, 1889, pp. 67–74; Norlind,
_Problem_, 1918, pp. 48–54; and more especially Boffito’s elaborate
discussion of the history of this theory and of ancient, Arabic, and
Christian doctrines of the relations of land and water in general
(Boffito, _op. cit._). For the theory as developed in the sixteenth,
seventeenth, and eighteenth centuries see Wisotzki, _Zeitströmungen_,
1897, pp. 39–57. The matter was discussed in a small treatise,
_Quaestio de aqua et terra_, which has been attributed to Dante but is
of doubtful authenticity (see above, p. 410, note 98). This is an
argument against the possibility of eccentric spheres; the “emergent
land” of the northern hemisphere is ascribed to the attractive force
of the stars of that hemisphere.

Neckam believed that the level of the sea is higher than that of the
lands, upon which the waters are prevented from encroaching only by
the divine power. “Mare vero superius est litoribus, ut visus docet.
Unde divinae jussioni attribuendum est, quod metas positas a Domino
non transgreditur mare” (_De nat. rer._, II, 49; _De laud. div. sap._,
III, 127–142). This curious doctrine persisted until the eighteenth
century; see Wisotzki, _op. cit._, pp. 39–57. “Mare etiam e litoribus
ascendere videtur, secundum judicium visus. Fidem etiam facit
proposito, videlicet quod aqua in sphericam formam tendat, guttae
pluvialis concavatio in petra. Nisi enim rotunda esset gutta, non
esset concavatio rotunda. Ros enim matutinus, qui rotundus est, verum
esse docet quod diximus. Per rotunditatem autem perfectio
intelligitur. Unde mens humana, per aquam designata, tendere habet ad
perfectionem” (_De nat. rer._, II, 14). See above, p. 369, note 35.

C. B. Jourdain, _Dissertation_, 1838, p. 75. Hildegard of Bingen
speaks of the tides thus: “Et quoniam in oriente magna profunditas
arenae et litoris est, idcirco mare superhabundando et se dilatando
ibi non effluit; in occidente autem et in austro ac in aquilone tanta
profunditas arenarum et litoris non est. Ideo ibi multotiens effluit
magnas et latas effusiones ibi faciens, cum ab igne procellarum in
insaniam commovetur, ut praedictum est. Unde ibi multa inutilia et
sordida in se colligit atque putredines hominum, pecorum, avium et
vermium sibi attrahit. Et idcirco fontes et flumina, quae de partibus
istis de mari effluunt, tam sana et tam bona non sunt sicut illa, quae
de orientali mari effluunt” (_Causae et curae_, I, Kaiser’s edit., p.
24).

eo quod aliquae sunt imagines stellarum in una quarta et in alia,
quoniam, quando planeta est super unam quartam mundi, tunc terra
interponitur inter corpus eius et aliam quartam. Propterea, si hoc

Footnote 873:
In the dialogue constituting the _Quaestiones naturales_ Adelard’s
nephew asks if the following theory is true: “Aiunt enim verum
occeanum per torridam fluentem brachia immense quantitatis fluentia ab
orientali et occidentali plaga in articam et in antarticam refundere
regionem. Illis igitur vi magna confluentibus redundationem hanc fieri
dicunt ut ictus nobis accessum pariat, cessio vero recessum.” To this
Adelard replies: “Philosophorum dictis invidere non ausim; illud tamen
audacter affirmem: si ita ut aiunt maxima conveniunt brachia, semel
comixtis undis secundo ictum non fieri neque enim convenit iterum eas
separari; vel certe si iterum collidantur minor erit secundus ictus
quam primus et tertius quam secundus itaque et quandoque minimus,
deinde nullus. Videant igitur illi quid dixerint; ego pro me breviter
respondebo. Recursus itaque brachiorum colligo; eorundem etiam
obviationibus non contradico; non tamen ea conflui vel collidi
concedo. Impotentie autem huius causam in ipsius terre situ facio. Cum
enim ipsa brachia sibi obviare atque confluere impetuose festinent,
fit tandem cum montium interpositione tum ipsius terre situ quodam
elatiore ut ab eodem cursu dum deficiunt referantur. Itaque fit ut quo
ea paternus motus ac naturalis impellit, ab eodem loci ipsius reducat
situs. Licet non ignorem quosdam esse qui hunc motum nili mari idest
caribdi dicant estuare. Quod si verum esset in maribus illis que
torride zone viciniora sunt vis talis nec minus valeret; nunc vero
illa omni fere tali carent agitatione; eo videlicet quod ab illa causa
quam supra scripsimus procul remota sunt” (_Quaest. nat._, 52 (53)).
It is not altogether clear as to what is meant by the last two
sentences of this quotation, which is here given as in the printed
text (see the Bibliography under Adelard, II) without collation from
the manuscripts (see Haskins, _Studies_, 1924, p. 26). If the word
_nili_ is a corruption of _lunae_, they may possibly be interpreted as
a denial of the lunar control theory of the tides. A passage from the
_Disputationes adversus astrologos_ of Giovanni Pico della Mirandola
according to Duhem, _Système_, vol. iii, 1915, p. 116, cites a certain
“Adelandus” as giving expression to views closely allied to those
expressed in the preceding quotation. If Adelard is meant by
“Adelandus,” as Duhem assumes (_ibid._, pp. 116–117), Pico’s citation
may well refer to this chapter of the _Quaestiones naturales_.
Adelandus, in any case, is made categorically to deny the possibility
of lunar control over the tides. Incidentally, it may be added that
Duhem was unfamiliar with the text of the _Quaestiones naturales_ at
the time that he wrote the third volume of his _Système du monde_ and
that Almagià’s otherwise exhaustive monograph on the history of
theories of the tides gives us nothing on Adelard. Examination of the
manuscripts (Haskins, _loc. cit._) might throw light on the problem.
The phrase “mari idest caribdi,” in the next-to-the-last sentence of
the quotation above, is not found in the manuscript copy of the
_Quaestiones naturales_ referred to in the Bibliography under Adelard,
II. Gollancz’s translation of this phrase, “one sea, the Caribbean” is
an obvious absurdity (Gollancz, _Dodi ve-Nechdi_, 1920, p. 141).

Footnote 877:
In the _De imagine mundi_, I, 40, there is extraordinary confusion
regarding the entire subject of the tides. There are said to be two
tides daily, corresponding to the rising and setting of the moon. When
the moon waxes, the height of the tides becomes greater; when it
wanes, the height diminishes. When the moon at the time of the
equinoxes is nearest to the earth, the floods rise to their highest;
at the time of the solstices they rise less high on account of the
distance of the moon. There is also said to be a tidal cycle of
nineteen years. So far, these ideas were drawn from Bede; but in the
succeeding chapter (41) there comes an echo of Paul the Deacon’s
description (_Hist. gentis Langobard._, I, 6, as cited by Almagià, _La
dottrina_, 1905, p. 51) of the great whirlpool, which “in exortu lunae
majori aestu fluctus involvit et revomit.”

William the Breton in another connection (_Philippis_, VIII, 43–99)
discusses the tides near Mont St. Michel in Brittany. His information
appears to have been fairly correct, and he notes among other details
that there is exceptionally high water at the times of the vernal and
autumnal equinoxes. He makes no attempt to explain the cause of the
ebb and flood, asserting that this transcends the knowledge of man. He
puts forth, however, the singular suggestion that it is just as likely
that the tides may cause the motion of the moon as vice versa, because
the sea was created before the moon:
“Rursus an a luna maris hec inflatio fiat,
An magis a pelago fluat hec variatio lune,
Cum pelagus luna constet prius esse creatum,
Posteriusque sui nunquam sit causa prioris,
Nullaque res habitum trahat a non ente vel actum.”

vol. i, pp. 181–182 and p. 182, note 1. Benjamin of Tudela places the
clotted sea in the Far East (_Itinerary_, Adler’s transl., 1907, p.
66, and above p. 272). In early French literature the sea is often
referred to as _la mer betée_ (see Frahm, _Das Meer_, 1914, pp.
76–77).
Many theories have been adduced to explain the origins of this
persistent rumor of a clotted sea. It may have arisen through
distorted reports of floating masses of seaweed or of the Sargasso
Sea. It has also been suggested that experiences in dead water such as
that described by Fridtjof Nansen (_Farthest North_, New York, 1897,
vol. i, p. 196) may have contributed to the formation of the legend.
Such dead water, Nansen explains, is caused by the presence of a layer
of fresh water from melted ice over the surface of the sea water. See
Frahm, _loc. cit._; Koch, _Das Meer_, 1910, pp. 21–22. For another

of the waters of the Dead Sea. The opposite theory, however, had been

sticks float, nor can a man swim, but whatever is cast into it sinks
to the bottom” (White, _Warfare_, 1920, vol. ii, p. 228).

Peter Comestor stated that on the third day of the Creation the earth

explained as follows: (1) _arida_, because the earth appeared (_quia
apparuit_); (2) _humus_, because it was still humid; (3) _terra_,
because it was trodden upon (_quia teritur_) by the feet of animals;
(4) _solum_, because, of the four elements, it forms the one that is
solid; and, finally, (5) _tellus_, because it endures (_quia tolerat_)
the labors of man (_Hist. schol._, Gen. 5). See Zöckler, _Geschichte_,

schol._, Gen. 3, cited by Liebrecht, _Gervasius von Tilbury_, 1856, p.
62, note 6**).

Ireland was very widespread in the Middle Ages. It is found in Bede’s
_Historia ecclesiastica_, I, 1 (Giles’s edit., vol. ii, p. 34), which
Giraldus goes on to quote at length on the subject (_Top. Hiber._, I,
31). It also appears in Gervase of Tilbury’s _Otia imperialia_, vol.
i, p. 917 (see Liebrecht, _op. cit._, p. 88, note 21). Solinus,
_Collectanea_, 22 (Mommsen’s edit., p. 101), and Isidore, _Etym._,
XIV, 6, ascribe similar properties to the earth of the Isle of Thanet.
In his _Letter_, Prester John boasts that some of his territories are

Benl, _Frühere und spätere Hypothesen_, 1905, pp. 1–14, discusses the
origin and development in antiquity and the Middle Ages of theories
regarding the distribution of the principal mountain systems of the
known world, the Taurus-Caucasus-Imaus range of Asia, the Rhipaean
Mountains of the far north, and the Mountains of the Moon of Africa.
The subsequent elaboration of these theories between the sixteenth and
nineteenth centuries, when the conception was developed by some
geographers of a symmetrical, rectilinear arrangement of the mountain
ranges of the entire globe is treated by Wisotzki, _Zeitströmungen_,
1897, pp. 131–192, and by Benl, _op. cit._, pp. 15–50.

Gervase said that the waters for the Flood came from the bowels of the
earth and from the air above. They rose to a level of fifteen cubits
above the summits of the mountains which are now in existence, “quia
tunc terram dicunt in planitie factam” (_Otia imper._, vol. i, p.
907). See above, pp. 170–171.

This translation is from Geikie, _Founders of Geology_, 1905, p. 43.
The processes of erosion by winds and water as a cause for the
inequalities of the earth’s surface are much more in evidence in arid
regions than in regions of dense vegetation. It is therefore not
surprising that these processes were recognized by Moslems like
Avicenna (if it be he from whom Alfred of Sareshel translated the
above quotation) and Ḥamd-Allāh Mustaufī, a Persian writer of the
early fourteenth century, who dwelt in the arid countries of the East.
The latter writes: “... the sun’s heat ... beginning to act on the
stone, this loses its hardness and is broken up; which process
continually accelerated by the succession of many nights and days,
cracks appear, splitting the rocks, which same are thus again turned
to earth. Then by the action of earthquakes mountain peaks are
demolished, while by the blowing of the winds and the running waters
the soft earth is carried from one place to another, yet all that is
rock and hard soil will remain fixed, whereby heights and hollows are
formed, and it is these heights that are mountain ranges” (Guy Le
Strange, transl., _The Geographical Part of the Nuzhat-al-Qulūb
Composed by Ḥamd-Allāh Mustawfī of Qazwīn in 740 (1340)_, London and
Leiden, 1919, p. 180).
Footnote 975:
_De sancta trinitate_, Gen. I, 34; see also Zöckler, _Geschichte_,
vol. i, 1877, p. 396. That teleological reasoning of this sort was not
confined to the medieval period may be seen from the following
paragraph from R. J. Sullivan, _A View of Nature in Letters to a
Traveller Among the Alps_, London, 1794, vol. I, p. 105: “On a cursory
view it must be acknowledged, the surface of our earth exhibits no
great regularity or order. In its outward appearance it strikes us
with heighths, depths, plains, seas, marshes, rivers, caverns, gulfs,
volcanoes, and a vast variety of other discordant objects;... Yet all
these apparent deformities are absolutely necessary to vegetation and
animal existence. Were the earth’s surface smooth and regular, we
should not have those beautiful hills which furnish water. A dreary
ocean would cover the globe, which would in such case be suited only
for the habitation of fishes. As it is, the motions of the sea and the
currents of the air are regulated by fixed laws. The returns of the
seasons are uniform, and the rigour of Winter invariably gives place
to the verdure of Spring. Men, animals, and plants consequently
succeed one another, and flourish in their destined soils.”
