A copious treatise of husbandry, by an Arabian of Seville, in the xiith century, is in the Escurial library, and Casiri had some thoughts of translating it. He gives a list of the authors quoted, Arabs as well as Greeks, Latins, etc.; but it is much if the Andalusian saw these strangers through the medium of his countryman Columella, (Casiri, Bibliot. Arabico-Hispana, tom. i. p. 323 - 338.)
