When Franceschetto Cybò was in Perugia in July 1488, with a Papal commission to act as peacemaker,[362] many citizens came to him with complaints of the intolerable state of the city. They declared that right and justice had lost all power, and begged him to give his assistance in putting an end to the evil. Franceschetto was not lacking in goodwill; but to cure such a moral cancer required a different sort of man, and the result justified the opinion expressed by Lorenzo in a letter to Lanfredini when this difficult mission was conferred by the Pope on his son. Franceschetto’s deliberations with the representatives of the great families, and the remonstrances made in Rome to divers noble Perugians, were all equally vain. At the end of October there was a bloody fight in and around the square before the palace of the Priori; small artillery was actually employed, houses were set on fire, the cathedral of San Lorenzo was used as a fortress, and barricades were constructed. Throughout the next day the street-fighting continued, with plundering and burning, and the prisons were broken open. The governor, who came back when the tumult was at its height, was received with shouts of ‘Church! Church!’ and notwithstanding all he could do his influence was powerless to quell the disturbance. At last the Oddi were beaten and forced to leave the city and flee to Castiglione del Lago (on Trasimene), where they and their numerous adherents set up a camp. The fight threatened to spread over the whole neighbouring country, as most of the fortresses belonged to the nobility; Spello, Fuligno, and other important places were already in arms and at open war with each other, the Vitelli, Orsini, and others taking part in the contest.
