OMAR TIBERIADIS. Liber de nativitatibus & interrogationibus. [colophon:] Venice, J. B. Sessa, March 26, 1503. Small 4to, 1 (b.) + 63p + 1 + 1 l(b.), with a fine, large allegorical woodcut, and Sessa's cat and mouse device on title, one woodcut diagram, and several tables; old Russian library stamp of the Imperial Library on title and two further leaves; 19th century green glazed paper boards, joints starting. The very rare first edition of the major independents works of Umar al-Tabari, on genethlialogy and astrological interrogations, and the only works of his to be translated into Latin and published in the West. They were "repeatedly quoted by Arabic and Latin writers, and esteemed second only to the work of Mashallah and Albumasar. One point of value was probably the presentation of the doctrines of Dorotheus [of Sidon]" (Carmody). The Arabic version of Dorotheus was due to Omar Tiberiadis. The allegorical woodcut shows Jupiter enthroned presiding over Satrun and Mars, surrounded by clouds, the signs of the zodaic interspersed in the design, the sun and the moon in the top corners.
