Benedetto was one of the richest citizens, a man of unassuming manners, an ardent lover of the liberties of his country, and one to whom tyrannical measures were in the highest degree offensive; so that he was easily induced to concur in their views and consent to Giorgio’s ruin. His enmity against the nobles of the people and the Guelphs, and his friendship for the plebeians, were caused by the insolence and tyrannical proceedings of the former; but finding that the plebeians had soon become quite as insolent, he quickly separated himself from them; and the injuries committed by them against the citizens were done wholly without his consent. So that the same motives which made him join the plebeians induced him to leave them.
Having gained Benedetto and the leaders of the trades to their side, they provided themselves with arms and made Giorgio prisoner. Tommaso fled. The next day Giorgio was beheaded; which struck so great a terror into his party, that none ventured to express the slightest disapprobation, but each seemed anxious to be foremost in defense of the measure. On being led to execution, in the presence of that people who only a short time before had idolized him, Giorgio complained of his hard fortune, and the malignity of those citizens who, having done him an undeserved injury, had compelled him to honor and support a mob, possessing neither faith nor gratitude. Observing Benedetto Alberti among those who had armed themselves for the preservation of order, he said, “Do you, too, consent, Benedetto, that this injury shall be done to me? Were I in your place and you in mine, I would take care that no one should injure you. I tell you, however, this day is the end of my troubles and the beginning of yours.” He then blamed himself for having confided too much in a people who may be excited and inflamed by every word, motion, and breath of suspicion. With these complaints he died in the midst of his armed enemies, delighted at his fall. Some of his most intimate associates were also put to death, and their bodies dragged about by the mob.
