AVERROIS. Abu-al-Walid Muhammad ibn-Ahmad ibn-Muhammad ibn-Rushd, 1126-1198, was born in Cordova and died in Marrakesh. He became a judge in both Seville and Cordova and, in 1182, physician to the Almohad caliph, Abu-Ya'qub Yusuf at Marrakesh. His prominence lasted until the reign of the following caliph, with whom he held a favorable position at first. In 1195, however, Caliph Ya'qub al-Mansur banished ibn-Rushd back to Cordova and ordered his writings, except the strictly scientific ones, burnt. The caliph seems to have changed his mind subsequently, for ibn-Rushd was back in Marrakesh in 1196, where he died in 1198. His chief works are a Compendium (a translation of Aristotle's Posterior Analytics) in 1170, short and middle-length commentaries or paraphrases on Aristotle's De caelo et mundo (On the Heavens), Physica (Physics), De generatione et corruptione (On Generation and Corruption), De anima (On the Soul), De sensu et sensibilibus (On the Senses and Sensibilities), and Meteorologica (Meteorology), composed in 1177, and a Great Commentary on many of the same works, including the Metaphysica (Metaphysics), composed in 1186. The Arabic commentary on The Great Commentary is lost but remains extant in Michael Scot's Latin translation, done between 1217 and 1220 at Toledo before he moved to Italy. Ibn-Rushd also wrote commentaries on Galen's Treatise on Fevers. Herman the German's translations of ibn-Rushd's commentaries on Aristotle date from 1240 and 1254. Merton College had, between 1360 and 1385, a manuscript of Averroes's work called Liber universalis de medicina (The Universal Book of Medicine), translated from the Arabic Kitab-al-Kulliyat.

Averrois appears in the Doctor's catalogue of authorities, Gen Prol 433. [Aristotile: Avycen]

Averrois is the ME variant of Latin Averroes, a development from the Arabic patronymic, ibn-Rushd.
