Girolamo Savonarola (September 21, 1452 – May 23, 1498), was an Italian Dominican priest and leader of Florence from 1494 until his execution in 1498. He was known for his book burning, destruction of what he considered immoral art, and hostility to the Renaissance. He vehemently preached against the moral corruption of much of the clergy at the time, and his main opponent was Pope Alexander VI (Rodrigo Borgia).
