While they were arranging to take possession of the republic, their design became known to the Signory, who, having taken a man named Simone, learned from him the particulars of the conspiracy, and that the outbreak was to take place on the following day. Finding the danger so pressing, they called together the colleagues and those citizens who with the syndics of the arts were endeavoring to effect the union of the city. It was then evening, and they advised the signors to assemble the consuls of the trades, who proposed that whatever armed force was in Florence should be collected, and with the Gonfaloniers of the people and their companies, meet under arms in the piazza next morning. It happened that while Simone was being tortured, a man named Niccolo da San Friano was regulating the palace clock, and becoming acquainted with what was going on, returned home and spread the report of it in his neighborhood, so that presently the piazza of St. Spirito was occupied by above a thousand men. This soon became known to the other conspirators, and San Pietro Maggiore and St. Lorenzo, their places of assembly, were presently full of them, all under arms.
