Gersonides 1288 – 1344

Levi ben Gershon, known by the Latinized name Gersonides, was a fourteenth-century Jewish philosopher, astronomer, mathematician, and biblical exegete who lived in Provence. His Wars of the Lord engaged the philosophical heritage of Maimonides and Aristotle on the central questions of the soul, prophecy, divine knowledge, providence, creation, and miracle, defending a number of distinctive positions, including a creation from primordial matter and a qualified divine omniscience. He produced commentaries on most of the Hebrew Bible, original work in trigonometry and astronomy, and the invention of the Jacob's staff for celestial measurement.
