It is a work of sound scholarship dealing with an interesting historical figure and his unique cultural world. The author focuses correctly on the transition from Italian to Ottoman Jewish culture in the life of David Messer Leon and reveals much about the continuities and discontinuities between both societies. He nicely fuses social and intellectual history, and uses a life to illuminate a number of interesting and important cultural trends among early modern Jews, particularly the integration of kabbalah and philosophy, Humanism and Thomism. The presentation of the symbiotic nature of Jewish culture with contemporary intellectual trends and the appropriation of Christian theological strategies by a Jewish thinker to explain Judaism make this study a fascinating one.
