This is a print on demand Publication. Levi ben Gerson (LBG) (1288-1344), was a prominent scholar in Orange (France) who wrote in Hebrew on biblical exegesis, philosophy, theology, & the sciences. Although Levi referred to astrology in his main work, “Milhamot Adonai” (”The Wars of the Lord”), his only known work in this domain is edited here for the first time. In this prognostication, based on the conjunction of Saturn & Jupiter to take place in 1345, Levi depended upon his own astronomical theories for the positions of the Sun & the Moon, & upon Abraham Ibn Ezra for astrological interpretations.
