Michael Scot (born c. 1175—died c. 1235) was a Scottish scholar and mathematician whose translations of Aristotle from Arabic and Hebrew into Latin are a landmark in the reception of that philosopher in western Europe.
Scot was famous in the European Middle Ages as an astrologer and soon acquired a popular reputation as a wizard. He is first recorded at Toledo in 1217, where he finished translating the treatise of al-Biṭrūjī (Alpetragius) on the sphere. In 1220 he was in Bologna and during the years 1224–27 may have been in papal service, as he is mentioned in several papal letters. A pluralist, he was promoted archbishop of Cashel in Ireland (May 1224) but declined the see a month later. He seems, however, to have held benefices in Italy from time to time. After 1227 he was at the Sicilian court of the Holy Roman emperor Frederick II and was mentioned as recently dead in a poem written early in 1236.
His works are mainly undated, but those on natural philosophy seem to predominate in his earlier, Spanish period, and those on astrology in his later, Sicilian period. At Toledo, in addition to his translation of al-Biṭrūjī, Scot translated Aristotle’s Historia animalium from Hebrew or Arabic. He also translated, perhaps at this time, Aristotle’s De caelo, and he was probably responsible for the translations of the De anima and the commentary by Averroës that is found in the same manuscripts. There is no evidence that Scot translated Aristotle’s Physics, Metaphysics, or Ethics.
He wrote three treatises on astrology, and several alchemical works were ascribed to him. He appears in Dante’s Inferno (xx) among the magicians and soothsayers and has the same role in Boccaccio.
