Abstract

As one of the earliest Western physics teachers, Richard Rufus of Cornwall helped transform Western natural philosophy in the 13th century. But despite the importance of Rufus's works, they were effectively lost for 500 years, and the Physics commentary is the first complete work of his ever to be printed. Rufus taught at the Universities of Paris and Oxford from 1231 to 1256, at the very time when exposure to Aristotle's libri naturales was revolutionizing the academic curriculum; indeed Rufus gave the earliest surviving lectures on physics and metaphysics. Rufus's challenges to the views of Aristotle and the commentator Averroes proved to be enormously influential: his accounts of projectile motion, the place of the heavens, and creation, were to be taken up by the likes of Franciscus de Marchia, Roger Bacon, Thomas Aquinas and Bonaventure.
