Nicole Oresme, a mathematician, philosopher, and theologian, stood as one of the most original and influential thinkers of the Late Middle Ages. This volume presents the critical edition of Oresme's earliest work, his first cycle of lectures on Aristotle's Meteorology (1346). Transcribed directly by one of his students at Paris Arts Faculty, this text explores problems of physics, cosmology, geology, and optics, providing invaluable insights into late medieval philosophy of nature.
