Girolamo Savonarola, the fifteenth-century doom-saying friar, embraced the revolution of the Florentine republic and prophesied that it would become the center of a New Age of Christian renewal and world domination. This new biography, the culmination of many decades of study, presents an original interpretation of Savonarola's prophetic career and a highly nuanced assessment of his vision and motivations.

Weinstein sorts out the multiple strands that connect Savonarola to his time and place, following him from his youthful rejection of a world he regarded as corrupt, to his engagement with that world to save it from itself, to his shattering confession—an admission that he had invented his prophesies and faked his visions. Was his confession sincere? A forgery circulated by his inquisitors? Or an attempt to escape bone-breaking torture? Weinstein offers a highly innovative analysis of the testimony to provide the first truly satisfying account of Savonarola and his fate as a failed prophet.
