Two manuscripts of Idrisi exist in the Bibliothèque Nationale, Paris, and other two in the Bodleian Library, Oxford. One of the English MSS., brought from Egypt by Greaves, is illustrated by a map of the known world, and by thirty-three sectional maps (for each part of the first three climates). The second manuscript, brought by Pococke from Syria, bears the date of A.H. 906, or A.D. 1500. It consists of 320 leaves, and is illustrated by one general and seventy-seven particular maps, the latter consequently including all the parts of every climate. The general map was published by Dr Vincent in his _Periplus of the Erythraean Sea_. A copy of Idrisi's work in the Escorial was destroyed by the fire of 1671. An epitome of Idrisi's geography, in the original Arabic, was printed, with many errors, in 1592 at the Medicean press in Rome, from a MS. preserved in the Grand Ducal library at Florence (_De geographia universali. Hortulus cultissimus ..._ ). Even the description of Mecca is here omitted. Pococke supplied it from his MS. In many bibliographical works this impression has been wrongly characterized as one of the rarest of books. In 1619 two Maronite scholars, Gabriel Sionita, and Joannes Hezronita, published at Paris a Latin 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 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. George Hieronymus Velschius, a German 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 Jena. Casiri (_Bib. Ar. Hisp._ ii. 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 Hartmann (_Commentatio de geographia Africae Edrisiana_, Göttingen, 1791, and _Edrisii Africa_, Göttingen, 1796), Here are collected the notices of each region in other Moslem writers, so as to form, for the time, a fairly complete body of Arabic geography as to Africa. Hartmann afterwards published Idrisi's Spain (_Hispania_, Marburg, 3 vols., 1802-1818).
