AL-MAJUSI ‘ALI IBN AL-‘ABBAS (d. 994). Liber totius medicine necessaria continens quem . . .  1523.

Haly Abbas, as he was known in the Latin west, was a native of Ahwaz in southwestern Persia and, in all probability, studied medicine at nearby Jundi-Shapur. He served as court physician to the Buyid ruler ‘Adud ad-Dawlah (d. 983) in Baghdad. This book’s clear, direct style, good organization, completeness, and systematic description of contemporary medical knowledge and thought undoubtedly contributed to its becoming the standard medical text until Avicenna’s Canon appeared a century later.
