Sa‘d b. Mansūr Ibn Kammūna, a Jewish polymath whosewritings are now receiving a good deal of scholarlyattention, worked in Baghdad under the aegis of theMongol rulers and their courtiers. Born early in thethirteenth century, so it seems, he was forced toflee the capital after rioters protested against hisbook which compared the three revealed monotheisticfaiths; he died in the 1280s. His oeuvre includes atreatise on ophthalmology, no longer extant;quotations from it are however available in thewriting of another ophthalmologist, Sadaqa ibnIbrāhīm al-Shādhilī. From these we learn that IbnKammūna practiced medicine in Aleppo (Halab).
I acknowledge with gratitude the very helpfulcriticisms of Charles Manekin and Tony Street onissues of logic and Emilie Savage-Smith withregard to medicine. Leigh Chipman, A.I. Sabra, andHossein Ziai were also kind enough to answerqueries. Hermann Landolt offered some importantcriticisms to the final draft of this paper.Responsibility for the contents of this studyrests with the author alone.
