The Annus Magnus in Albert the Great's Parisian Theological Works: De IV coaequaevis and Commentarii in libros Sententiarum

According to the doctrine of the Great Year, after a long period of time the same astral configurations reappear and the planets return to their original positions. The end of a world cycle is marked by a natural cataclysm, after which the world is restored to its original state and history repeats itself. This article deals with Albert the Great’s views on the Great Year, focussing on two of his early theological works (the De IV coaequaevis and the Sentences commentary). The evidence here provided offers a comprehensive overview of the variety of contexts and themes which Albert considers to be related to the Great Year. He is fully aware of the many doctrinal implications of the concept of the Great Year. His analysis is deeply embedded in the astronomical discussions on the phenomenon of the precession of the equinoxes. A predominantly scientific approach is evident in the care with which he distinguishes the different types of Great Year. The major contribution of these works to the debate lies in the analysis of the impact of the Great Year on Christian eschatology and, more generally, in the investigation of the relationship between astrology and physics, on the one hand, and eschatology, on the other.
