Girolamo Savonarola was a Dominican friar from Ferrara whose apocalyptic preaching made him one of the most powerful public voices in Florence during the 1490s. From the convent of San Marco he attacked clerical corruption, luxury and political immorality while predicting divine punishment and renewal. When Charles VIII of France invaded Italy in 1494 and the Medici regime collapsed, Savonarola’s reputation as a prophet grew, and he became an important moral influence on the republican government that replaced Medici rule.
Savonarola promoted a programme of Christian civic reform that encouraged almsgiving and stricter public morality but also supported intrusive campaigns against gambling, sexual behaviour and luxury. The famous “Bonfire of the Vanities” became the emblem of this phase. His refusal to moderate his attacks on Pope Alexander VI led to excommunication, while political support in Florence eroded. After a proposed ordeal by fire collapsed amid confusion, Savonarola was arrested, interrogated and condemned. He and two Dominican companions were hanged and burned in Piazza della Signoria on 23 May 1498.
In D. V. Bishop’s Ritual of Fire, A wealthy merchant is found hanged and burning in the city’s main square, killed in deliberate imitation of Girolamo Savonarola’s execution forty years earlier. In Sarah Dunant’s The Birth of Venus, The French invasion drives the Medici from Florence and allows Girolamo Savonarola’s religious movement to reshape the republic.
