Judah Loew, better known as the Maharal of Prague, was a pivotal personality in late medieval European Judaism. Best known from the popular legend that credited him with the creation of a golem‹an artificial human with superhuman powers - his true importance lay in his comprehensive exposition of a unique expression of Jewish mystical theology, his call for a reformation of Jewish communal life, and his influence on subsequent Jewish life and thought. Byron Sherwin's lucid exposition of Loew¹s life and works, the legends that surrounded him, and the ideas developed in his massive writings 'reveals the concealed' by unravelling the often obscure nature of his mystical theology, his polemical jousts against past and contemporary Jewish scholars, and his innovative program for social and educational reform.
