By the end of the fifteenth century, Florence was well established as the home of the Renaissance. As generous patrons to the likes of Botticelli and Michelangelo, the ruling Medici embodied the progressive humanist spirit of the age, and in Lorenzo the Magnificent they possessed a diplomat capable of guarding the militarily weak city in a climate of constantly shifting allegiances between the major Italian powers. However, in the form of Savonarola, an unprepossessing provincial monk, Lorenzo found his nemesis. Filled with Old Testament fury and prophecies of doom, Savonarola's sermons reverberated among a disenfranchised population, who preferred medieval Biblical certainties to the philosophical interrogations and intoxicating surface glitter of the Renaissance. Savonarola's aim was to establish a 'City of God' for his followers, a new kind of democratic state, the likes of which the world had never seen before.The battle which this provoked would be a fight to the death, a series of sensational events - invasions, trials by fire, the 'Bonfire of the Vanities', terrible executions and mysterious deaths - featuring a cast of the most important and charismatic Renaissance figures. This famous struggle has often been portrayed as a simple clash of wills between a benign ruler and religious fanatic, between secular pluralism and repressive extremism. However, in an exhilaratingly rich and deeply researched story, Paul Strathern reveals the paradoxes, self-doubts and political compromises which made the battle for the soul of the Renaissance city one of the most complex and important moments in Western history.
