IDRISI, or EDRISI [See also:Abu Abdallah Mahommed See also:Ibn Mahommed Ibn Abdallah Ibn Idrisi, c. A.D. 1099-1154]  , Arabic geographer . Very little is known of his See also:life . Having See also:left Islamic lands and become the courtier and panegyrist of a See also:Christian See also:prince, though himself a descendant of the See also:Prophet, he was probably regarded by strict Moslems as a See also:scandal, whose naive should not, if possible, be mentioned . His See also:great-grandfather, See also:Idrisi II., " Biamrillah," a member of the great princely See also:house which had reigned for a See also:time as caliphs in See also:north-See also:west See also:Africa, was prince of See also:Malaga, and likewise laid claim to the supreme See also:title (See also:Commander of the Faithful) . After his See also:death in 10J5, Malaga was seized by See also:Granada (10J7), and the Idrisi See also:family then probably migrated to See also:Ceuta, where a freedman of theirs held See also:power . Here the geographer appeals to have been See also:born in A.H . 493 (A.D . 1099) . He is said to have studied at See also:Cordova, and this tradition is See also:con-firmed by his elaborate and enthusiastic description of that See also:city in his See also:geography . From this See also:work we know that he had visited, at some See also:period of his life before A.D . 1154, both See also:Lisbon and the mines of See also:Andalusia . He had also once resided near See also:Morocco city, and once was at (Algerian) See also:Constantine .

More precisely, he tells us that in A.D . 1117-he went to see the See also:

cave of the Seven Sleepers at See also:Ephesus; he probably travelled extensively in See also:Asia See also:Minor . From doubtful readings in his See also:text some have inferred that he had seen See also:part of the coasts of See also:France and See also:England . We do not know when See also:Roger II. of See also:Sicily (See also:riot–1154) invited him to his See also:court, but it must have been between 1125 and 1150 . Idrisi made for the See also:Norman See also:king a See also:celestial See also:sphere and a disk representing the known See also:world of his See also:day—both in See also:silver . These only absorbed one-third of the See also:metal that had been given him for the work, but Roger bestowed on him the remaining two-thirds as a See also:present, adding to this See also:loo,000 pieces of See also:money and the See also:cargo of a richly-laden See also:ship from See also:Barcelona . Roger next enlisted Idrisi's services in the compilation of a fresh description of the " inhabited' See also:earth " from observation, and not merely from books . The king and his geographer See also:chose emissaries whom they sent out into various countries to observe, See also:record and See also:design; as they returned, Idrisi inserted in the new geography the See also:information they brought . Thus was gradually completed (by the See also:month of Shawwal, A.H . J48=See also:mid-See also:January, A.D . 1154), the famous work, best known, from its See also:patron and originator, as Al Rojari, but whose fullest title seems to have been, The going out of a Curious See also:Man to explore the Regions of the Globe, its Provinces, Islands, Cities and their Dimensions and Situation . This has been abbreviated to The Amusement of him who desires to See also:traverse the Earth, or The Relaxation of a Curious Mind .

The title of Nubian Geography, based upon Sionita and Hezronita's misreading of a passage See also:

relating to See also:Nubia and the See also:Nile, is entirely unwarranted and misleading . The Rogerian See also:Treatise contains a full description of the world as far as it was known to theauthor . The " inhabited earth "is divided into seven " climates," beginning at the equinoctial See also:line, and extending northwards to the limit at which the earth was supposed to be rendered uninhabitable by See also:cold . Each See also:climate is then divided by perpendicular lines into eleven equal parts, beginning with the western See also:coast of Africa and ending with the eastern coast of Asia . The whole world is thus formed into seventy-seven equal square compartments . The geographer begins with the first part of the first climate, including the westernmost part of the See also:Sahara and a small (north-See also:westerly) See also:section of the See also:Sudan (of which a vague knowledge had now been acquired by the Moslems of See also:Barbary), and thence proceeds eastward through the different divisions of this climate till he finds its termination in the See also:Sea of See also:China . He then returns to the first part of the second climate, and so proceeds till he reaches the See also:eleventh part of the seventh climate, which terminates in north-See also:east Asia, as he conceives that See also:continent . The inconveniences of the arrangement (ignoring all divisions, See also:physical, See also:political, linguistic or religious, which did not coincide with those of his "climates") are obvious . Though Idrisi was in such See also:close relations with one of the most civilized of Christian courts and states, we find few traces of his See also:influence on See also:European thought and knowledge . The See also:chief exception is perhaps in the delineation of Africa in the world-maps of See also:Marino See also:Sanuto (q.v.) and Pietro Vesconte . His See also:account of the voyage of the Maghrurin or " Deceived Men " of Lisbon in the See also:Atlantic (a voyage on which they seem to have visited See also:Madeira and one of the Canaries) may have had some effect in stimulating the later ocean enterprise of Christian mariners; but we have no See also:direct See also:evidence of this . Idrisi's Ptolemaic leanings give a distinctly See also:retrograde See also:character to certain parts of his work, such as east Africa and See also:south Asia; and, in spite of the record of the Lisbon Wanderers, he fully shares the See also:common Moslem dread of the See also:black, viscous, stormy and See also:wind-swept See also:waters of the western ocean, whose limits no one knew, and over which thick and perpetual darkness brooded .

At the same time his breadth of view, his clear recognition of scientific truths (such as the roundness of the world) and his wide knowledge and intelligent application of preceding work (such as that of See also:

Ptolemy, Masudi and Al Jayhani) must not be forgotten . He also preserves and embodies a considerable amount of private and See also:special information—especially as to Scandinavia (in whose delineation he far surpasses his predecessors), portions of the See also:African coast, the See also:river See also:Niger (whose name is perhaps first to be found, after Ptolemy's doubtful Nigeir, in Idrisi), portions of the African coast, See also:Egypt, See also:Syria, See also:Italy, France, the Adriatic See also:shore-lands, See also:Germany and the Atlantic islands . No other Arabic work contains a larger assortment of valuable See also:geographical facts; unfortunately the See also:place-names are often illegible or hopelessly corrupted in the See also:manuscripts . Idrisi's world-See also:map, with all its shortcomings, is perhaps the best product of that strangely feeble thing—the See also:Mahommedan cartography of the See also:middle ages . Besides the Rojari, Idrisi wrote another work, largely geographical, cited by Abulfida as The See also:Book of Kingdoms, but apparently entitled by its author The Gardens of Humanity and the Amusement of the Soul . This was composed for See also:William the See also:Bad (1154–1166), son and successor of Roger II., but is now lost . He likewise wrote, according to See also:Ibn Said, on Medicaments, and composed verses, which are referred to by the Sicilian Mahommedan poet Ibn Bashrun . Two manuscripts of Idrisi exist in the Bibliotheque Nationale, See also:Paris, and other two in the Bodleian Library, See also:Oxford . One of the See also:English See also:MSS., brought from Egypt by See also:Greaves, is illustrated by d map of the known world, and by See also:thirty-three sectional maps (for each part of,the first three climates) . The second See also:manuscript, brought by See also:Pococke from Syria, bears the date of A.13 . 906, or A.D . 1500 .

Phoenix-squares

It consists of 32oleaves. and is illustrated by one See also:

general and seventy-seven particular maps, the latter consequently including all the parts of every climate . The general map was published by Dr See also:Vincent in his Periplus of the Erythraean Sea . A copy of Idrisi's work in the See also:Escorial was destroyed by the See also:fire of 1671 . An- See also:epitome of Idrisi's geography, in the See also:original Arabic, was printed, with many errors, in 1592 at the Medicean See also:press in See also:Rome, from a MS. preserved in the See also:Grand Ducal library at See also:Florence (Re geographic universali, . Modulus cultissianus . . ) . Even the description of See also:Mecca is here omitted . Pococke supplied it from his MS . In many See also:bibliographical See also:works this impression has been wrongly characterized as one of the rarest of books . In 1619 two Maronite scholars, See also:Gabriel Sionita. and Joannes Hezronita, published at Paris a Latin See also:translation of this epitome (Geographia Nubiensis, id est, accuratissima totius orbis in VII. climata divisi descriptio) . Besides its many inaccuracies of detail, this edition, by its unlucky title of Nubian Geography, started a fresh and fundamental See also:error as to Idrisi's origin; this was founded on a misreading of a passage where Idrisi describes the Nile passing into Egypt through Nubia—not " terram nostram," as this version gives, but " terram illius " is here the true translation . See also:George Hieronymus Velschius, a See also:German See also:scholar, had prepared a copy of the Arabic original, with a Latin translation, which he purposed to have illustrated with notes; but death interrupted this design, and his manuscript remains in the university library of See also:Jena .

See also:

Casiri (Bib . Ar . Hisp . H . 13) mentions that he had determined to re-edit this work, but he appears never to have executed his intention . The part relating to Africa was ably edited by Johann Melchior See also:Hartmann (Commentatio de geographia Africae Edrisiana, See also:Gottingen, 1791, and Edrisii Africa, Gottingen, 1796) . Here are collected the notices of each region in other Moslem writers, so as to See also:form, for the time, a fairly See also:complete See also:body of Arabic geography as to Africa . Hartmann afterwards published Idrisi's See also:Spain (Hispania, See also:Marburg, 3 vols., 1802-1818) . An (indifferent) See also:French translation of the whole of Idrisi's geography (the only complete version which has yet appeared), based on one of the MSS, of the Bibliotheque Nationale, Paris, was published by Amedee See also:Jaubert in 1836–184o, and forms volumes v. and vi. of the Recueil de voyages issued by the Paris Societe de Geographic; but a See also:good and complete edition of the original text is still a desideratum . A number of See also:Oriental scholars at See also:Leiden deter-See also:mined in 1861 to undertake the task . Spain and western See also:Europe were assigned to See also:Dozy; eastern Europe and western Asia to Engelmann; central and eastern Asia to Defremery; and Africa to de See also:Goeje . The first portion of the work appeared in 1866, under the title of Description de l'Afrique et de l'Espagne See also:par Edrisi, texte arabe, public avec une traduction, See also:des notes et un glossaire par R .

Dozy et M . J. de Goeie (Leiden, E . J . See also:

Brill, 1866) ; but the other collaborators did not furnish their See also:quota . Other parts of Idrisi's work have been separately edited; e.g . " Spain " (Description de Espana de . Aledris), by J . A . See also:Conde, in Arabic and See also:Spanish (See also:Madrid, 1799) ; " Sicily " (Descrizione della Sicilia . . . di Elidris), by P . D . Magri and F .

See also:Schiaparelli, in Arabic and See also:Italian (Rome, 1883); " Syria " (Syria descripta a . El Edrisio . . . ), by E . F . C . Rosenmuller, in Arabic and Latin, 1825, and (Idrisii .
