The pope had heard of the tumults at Florence, and sent his legate, Niccolo da Prato, to settle them, who, being in high reputation both for his quality, learning, and mode of life, presently acquired so much of the people’s confidence, that authority was given him to establish such a government as he should think proper.  As he was of Ghibelline origin, he determined to recall the banished; but designing first to gain the affections of the lower orders, he renewed the ancient companies of the people, which increased the popular power and reduced that of the nobility.  The legate, thinking the multitude on his side, now endeavored to recall the banished, and, after attempting in many ways, none of which succeeded, he fell so completely under the suspicion of the government, that he was compelled to quit the city, and returned to the pope in great wrath, leaving Florence full of confusion and suffering under an interdict.  Neither was the city disturbed with one division alone, but by many; first the enmity between the people and the nobility, then that of the Ghibellines and the Guelphs, and lastly, of the Bianchi and the Neri.  All the citizens were, therefore, in arms, for many were dissatisfied with the departure of the legate, and wished for the return of the banished.  The first who set this disturbance on foot were the Medici and the Guinigi, who, with the legate, had discovered themselves in favor of the rebels; and thus skirmishes took place in many parts of the city.

In addition to these evils a fire occurred, which first broke out at the garden of St. Michael, in the houses of the Abati; it thence extended to those of the Capoinsacchi, and consumed them, with those of the Macci, Amieri, Toschi, Cipriani, Lamberti, Cavalcanti, and the whole of the New Market; from thence it spread to the gate of St. Maria, and burned it to the ground; turning from the old bridge, it destroyed the houses of the Gherardini, Pulci, Amidei, and Lucardesi, and with these so many others that the number amounted to seventeen hundred.  It was the opinion of many that this fire occurred by accident during the heat of the disturbances.  Others affirm that it was begun willfully by Neri Abati, prior of St. Pietro Scarragio, a dissolute character, fond of mischief, who, seeing the people occupied with the combat, took the opportunity of committing a wicked act, for which the citizens, being thus employed, could offer no remedy.  And to insure his success, he set fire to the house of his own brotherhood, where he had the best opportunity of doing it.  This was in the year 1304, Florence being afflicted both with fire and the sword.  Corso Donati alone remained unarmed in so many tumults; for he thought he would more easily become the arbitrator between the contending parties when, weary of strife, they should be inclined to accommodation.  They laid down their arms, however, rather from satiety of evil than from any desire of union; and the only consequence was, that the banished were not recalled, and the party which favored them remained inferior.
