When the news reached Florence, the Ghibellines trembled for their safety, and the people prepared to win back their own. An attempt at compromise was first made, under the auspices of Pope Clement. Two _Frati Gaudenti_ or "Cavalieri di Maria," members of an order of warrior monks from Bologna, were made Podestàs, one a Guelf and one a Ghibelline, to come to terms with the burghers. You may still trace the place where the Bottega and court of the Calimala stood in Mercato Nuovo (the Calimala being the Guild of dressers of foreign cloth--panni franceschi, as Villani calls it), near where the Via Porta Rossa now enters the present Via Calzaioli. Here the new council of thirty-six of the best citizens, burghers and artizans, with a few trusted members of the nobility, met every day to settle the affairs of the State. Dante has branded these two warrior monks as hypocrites, but, as Capponi says, from this Bottega issued at once and almost spontaneously the Republic of Florence. Their great achievement was the thorough organisation of the seven greater Guilds, of which more presently, to each of which were given consuls and rectors, and a gonfalon or ensign of its own, around which its followers might assemble in arms in defence of People and Commune. To counteract this, Guido Novello brought in more troops from the Ghibelline cities of Tuscany, and increased the taxes to pay his Germans; until he had fifteen hundred horsemen in the city under his command. With their aid the nobles, headed by the Lamberti, rushed to arms. The people rose _en masse_ and, headed by a Ghibelline noble, Gianni dei Soldanieri, who apparently had deserted his party in order to get control of the State (and who is placed by Dante in the Hell of traitors), raised barricades in the Piazza di Santa Trinità and in the Borgo SS. Apostoli, at the foot of the Tower of the Girolami, which still stands. The Ghibellines and Germans gathered in the Piazza di San Giovanni, held all the north-east of the town, and swept down upon the people's barricades under a heavy fire of darts and stones from towers and windows. But the street fighting put the horsemen at a hopeless disadvantage, and, repulsed in the assault, the Count and his followers evacuated the town. This was on St Martin's day, November 11th, 1266. The next day a half-hearted attempt to re-enter the city at the gate near the Ponte alla Carraia was made, but easily driven off; and for two centuries and more no foreigner set foot as conqueror in Florence.
