The Piazza Santa Trinità was a great place for social and other gatherings in mediæval and renaissance Florence. Here on the first of May 1300, a dance of girls was being held to greet the calends of May in the old Florentine fashion, when a band of mounted youths of the Donati, Pazzi and Spini came to blows with a rival company of the Cerchi and their allies; and thus the first blood was shed in the disastrous struggle between the Bianchi and Neri. A few days later a similar faction fight took place on the other side of the bridge, in the Piazza Frescobaldi, on the occasion of a lady's funeral. The great Palazzo Spini, opposite the church, was built at the end of the thirteenth and beginning of the fourteenth century by Geri Spini, the rich papal banker and one of the leaders of the "black" faction. Here he received the Pope's ambassadors and made a great display of his wealth and magnificence, as we gather from Boccaccio's _Decameron_, which gives us an amusing story of his friendship with Cisti the baker, and another of the witty repartees of Madonna Oretta, Geri's wife, a lady of the Malaspina. When Charles of Valois entered Florence in November 1301, Messer Geri entertained a portion of the French barons here, while the Prince himself took up his quarters with the Frescobaldi over the river; during that tumultuous period of Florentine history that followed the expulsion of the Bianchi, Geri was one of the most prominent politicians in the State. Savonarola's processions of friars and children used to pass through this piazza and over the bridge, returning by way of the Ponte Vecchio. On the Feast of Corpus Christi, 1497, as the Blessed Sacrament was being borne along, with many children carrying red crosses, they were set upon by some of the Compagnacci. The story is quaintly told by Landucci: "As the said procession was passing over the Bridge of Santa Trinità, certain youths were standing to see it pass, by the side of a little church which is on the bridge on the right hand going towards Santo Spirito. Seeing those children with the crosses, they said: 'Here are the children of Fra Girolamo.' And one of them coming up to them, took one of these crosses and, snatching it out of the hand of that child, broke it and threw it into the Arno, as though he had been an infidel; and all this he did for hatred of the Friar."
