In 1490, the prior of St. Marks was a famous Domincan called Savonarola. He lived in the cell that had once belonged to Cosimo Medici. He was a great preacher. He disliked Cosimo's grandson, Lorenzo Medici, who was often called "Lorenzo the Magnificent" (Lorenzo il Magnifico). He thought that Lorenzo had too much power and was acting like a prince. He preached against Lorenzo, against the Pope and against the Roman Catholic Church. He told everyone that the end of the world was near. Many people became frightened or depressed by the things that he said. Pope Alexander VI had Savonarola arrested. He was tortured and put to death in 1498. 60 years later, the Church agreed that, in fact, he had said nothing wrong.
