Michael Scot (1175 – c. 1232) was the first Latin translator of Averroes who translated the long commentaries of "Physics", "Metaphysics", "On the Soul" and "On the Heavens", as well as multiple middle and short commentaries, starting in 1217 in Paris and Toledo. Following this, European authors such as Hermannus Alemannus, William de Luna and Armengaud of Montpellier translated Averroes' other works, sometimes with help from Jewish authors. Soon after, Averroes' works propagated among Christian scholars in the scholastic tradition. His writing attracted a strong circle of followers known as the Latin Averroists. Paris and Padua were major centers of Latin Averroism, and its prominent thirteenth-century leaders included Siger of Brabant and Boethius of Dacia.
