The Speculum Astronomiae and Its Enigma: Astrology, Theology and Science in Albertus Magnus and his Contemporaries

The Speculum Astronomiae and Its Enigma: Astrology, Theology and Science in Albertus Magnus and his Contemporaries by Paola Zambelli is a rigorous historical and philosophical investigation into one of the most debated texts of the medieval intellectual world. Centered on the Speculum astronomiae, the book explores its authorship, meaning, and role within the broader discourse on astrology, theology, and natural philosophy during the 13th century.

Zambelli situates astrology not as marginal superstition, but as a foundational component of medieval scientific thought. Through detailed historiographical analysis, she reconstructs debates among scholars, theologians, and philosophers—particularly around figures like Albertus Magnus—and examines how astrology intersected with questions of divine providence, free will, and natural causation.

What distinguishes this work is its depth: it combines textual criticism, manuscript studies, and intellectual history to reassess long-standing assumptions about medieval science. It also includes the Latin text and English translation of the Speculum astronomiae, making it both a scholarly study and a primary source resource.
