In 1498 Savonarola again lifted up his voice; the church was not large enough, so he preached beneath the blue sky on the Piazza San Marco; and Fra Domenico Buonvicini da Pescia, in the eagerness of partisanship, said that his master's words would stand the ordeal of fire. Then came that tumultuous day of April 7th, the "Sunday of the Olives," when the Franciscans and Dominicans argued while the fire burnt out before them, when Savonarola's great spirit quailed within him, and the ordeal failed; a merciful rain quenching the flames which none dared to brave save the undaunted Fra Domenico himself. There was no painting done in the studio on that day we may be sure. Baccio was one of the surging, conflicting crowd gathered beneath the mingling shadows of Orcagna's arches and Arnolfo's great palace, and at eventide he was one of the armed partisans who protected the friar back to his convent, menaced not only by rains from heaven, but by the stormy wrath of an angry populace, defrauded of the sight they came to see. The next day was the one which determined the painter's future life. There was in the city a curious process of crystallisation of all the particles held in solution round the fire the previous day. The Palazzo Vecchio attracted about its doors the "Arrabiati." The "Compagnacci" assembled, armed, by the Duomo. The streets were full of detached parties of Piagnoni, treading ways of peril to their centre, San Marco. Passions raged and seethed all day, till at the hour of vespers a cry arose, "_à San Marco_," and thither the multitude--500 Compagnacci, and 300 Palleschi--rushed, armed with picks and arquebusses, &c. They killed some stray Piagnoni whom they found praying by a shrine, and placed guards at the streets which led to the convent; then the assault began. The church was dimly lighted. Savonarola and Fra Domenico kneeled on the steps of the altar, with many worshippers around them, singing tremulous hymns; amongst these were Francesco Valori, Ridolfi, and Baccio della Porta, but all armed, as Cronaca tells us. They still sang hymns when the doors were attacked with stones; then leaving the priests and women to pray for them the men rushed to the defence.
