An (indifferent) 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 Bibliothèque Nationale, Paris, was published by Amédée Jaubert in 1836-1840, and forms volumes v. and vi. of the _Recueil de voyages_ issued by the Paris Société de Géographie; but a good and complete edition of the original text is still a desideratum. A number of Oriental scholars at Leiden determined in 1861 to undertake the task. Spain and western Europe were assigned to Dozy; eastern Europe and western Asia to Engelmann; central and eastern Asia to Defrémery; and Africa to de Goeje. The first portion of the work appeared in 1866, under the title of _Description de l'Afrique et de l'Espagne par Edrisi, texte arabe, publié avec une traduction, des notes et un glossaire par R. Dozy et M. J. de Goeje_ (Leiden, E. J. Brill, 1866); but the other collaborators did not furnish their quota. Other parts of Idrisi's work have been separately edited; e.g. "Spain" (_Descripcion de España de ... Aledris_), by J. A. Condé, in Arabic and Spanish (Madrid, 1799); "Sicily" (_Descrizione della Sicilia ... di Elidris_), by P. D. Magri and F. Tardia (Palermo, 1764); "Italy" (_Italia descritta nel "libro del Re Ruggero," compilato da Edrisi_), by M. Amari and C. Schiaparelli, in Arabic and Italian (Rome, 1883); "Syria" (_Syria descripta a ... El Edrisio ..._ ), by E. F. C. Rosenmüller, in Arabic and Latin, 1825, and (_Idrisii ... Syria_), by J. Gildemeister (Bonn, 1885) (the last a Beilage to vol. viii. of the _Zeitschrift d. deutsch. Palästina-Vereins_). See also M. Casiri, _Bibliotheca Arabico-Hispana Escurialensis_ (2 vols., Madrid, 1760-1770); V. Lagus, "Idrisii notitiam terrarum Balticarum ex commerciis Scandinavorum et Italorum ... ortam esse" in _Atti del IV° Congresso internaz. degli orientalisti in Firenze_, p. 395 (Florence, 1880); R. A. Brandel "Om och ur den arabiske geografen Idrisi," _Akad. afhand._ (Upsala, 1894). (C. R. B.) IDUMAEA ([Greek: 'Idoumaia]), the Greek equivalent of Edom ([Hebrew: Edom]), a territory which, in the works of the Biblical writers, is considered to lie S.E. of the Dead Sea, between the land of Moab and the Gulf of Akaba. Its name, which is connected with the root meaning "red," is probably applied in reference to the red sandstone ranges of the mountains of Petra.[1] This etymology, however, is not certain. The apparently theophorous name Obed-Edom (2 Sam. vi. 10) shows that Edom is the name of a divinity. Of this there is other evidence; a Leiden papyrus names Etum as the wife of the Semitic fire-god Reshpu.
