Dot Porter, SIMS Curator for Digital Humanities at the University of Pennsylvania Library, presents a video Orientation to the University of Pennsylvania Library’s LJS 429, an illustrated introduction to natural philosophy, supposedly according to the principles of Isidore of Seville, but in fact representing later Aristotelian and Thomist thought and opposing the followers of Duns Scotus, including the 15th-century theologians Nicolas d’Orbelles (referred to in the manuscript as Dorbellus) and Etienne Brulefer (in the manuscript as Brulifer). Includes discussion of the proofs of existence of God; the use of the principle of deduction; the celestial spheres and compass points; and the elements, temperaments, and humors. Written in western Germany, probably Mainz, in the late 15th century.
