Samuel b. Judah ibn Tibbon (c. 1165-1232) is most famous for his translation of Maimonides’ Guide of the Perplexed into Hebrew. He translated other writings as well and produced original works of philosophy and biblical exegesis. This book makes available for the first time ever Ibn Tibbon’s Perush Qohelet, a sprawling adaptation of Maimonides’ method of exegesis to the complete verse-by-verse explication of a biblical book. The edition is presented with full annotation -- identifying Ibn Tibbon’s sources and explaining his ideas and terminology -- and analytical introduction, which presents the life and writings of the author, describes the commentary itself in detail, explains the method and philosophy of the commentary, and charts its historical influence. In later medieval Jewish thought, few figures were unaffected by this foundational work of Maimonideanism.
