And the said Cerchi were the heads of the White party in Florence, and with them held almost all the house of the Adimari, save the branch of the Cavicciuli; all the house of the Abati, which was then very powerful, and part of them were Guelf and part were Ghibelline; a great part of the Tosinghi, specially the branch of Baschiera; part of the house of the Bardi, and part of the Rossi, and likewise some of the Frescobaldi, and part of the Nerli and of the Mannelli, and all the Mozzi, which then were very powerful in riches and in estate; all those of the house of the Scali, and the greater part of the Gherardini, all the Malispini, and a great part of the Bostichi and Giandonati, of the Pigli, and of the Vecchietti and Arrigucci, and almost all the Cavalcanti, which were a great and powerful house, and all the Falconieri which were a powerful house of the people. And with them took part many houses and families of popolani, and lesser craftsmen, and all the Ghibelline magnates and popolani; and by reason of the great following which the Cerchi had, the government of the city was almost all in their power.

For the which thing the said Pope sent for M. Vieri de' Cerchi, and when he came before him, he prayed him to make peace with M. Corso Donati and with his party, referring their differences to him; and he promised him to put him and his followers into great and good estate, and to grant him such spiritual favours as he might ask of him. M. Vieri, albeit he was in other things a sage knight, in this was but little sage, and was too obstinate and capricious, insomuch that he would grant nought of the Pope's request; saying that he was at war with no man; wherefore he returned to Florence, and the Pope was moved with indignation against him and against his party. It came to pass a little while after that certain both of one party and of the other were riding through the city armed and on their guard, and with the party of the young Cerchi was Baldinaccio of the Adimari, and Baschiera of the Tosinghi, and Naldo of the Gherardini, and Giovanni Giacotti Malispini, with their followers, more than thirty on horseback; and with the young Donati were certain of the Pazzi and of
