At daybreak on the 21st of July, there did not appear in the piazza above eighty men in arms friendly to the Signory, and not one of the Gonfaloniers; for knowing the whole city to be in a state of insurrection they were afraid to leave their homes. The first body of plebeians that made its appearance was that which had assembled at San Pietro Maggiore; but the armed force did not venture to attack them. Then came the other multitudes, and finding no opposition, they loudly demanded their prisoners from the Signory; and being resolved to have them by force if they were not yielded to their threats, they burned the house of Luigi Guicciardini; and the Signory, for fear of greater mischief, set them at liberty. With this addition to their strength they took the Gonfalon of Justice from the bearer, and under the shadow of authority which it gave them, burned the houses of many citizens, selecting those whose owners had publicly or privately excited their hatred. Many citizens, to avenge themselves for private injuries, conducted them to the houses of their enemies; for it was quite sufficient to insure its destruction, if a single voice from the mob called out, "To the house of such a one," or if he who bore the Gonfalon took the road toward it. All the documents belonging to the woolen trade were burned, and after the commission of much violence, by way of associating it with something laudable, Salvestro de Medici and sixty-three other citizens were made knights, among whom were Benedetto and Antonio degli Alberti, Tommaso Strozzi and others similarly their friends; though many received the honor against their wills. It was a remarkable peculiarity of the riots, that many who had their houses burned, were on the same day, and by the same party made knights; so close were the kindness and the injury together. This circumstance occurred to Luigi Guicciardini, Gonfalonier of Justice.
