This Piazza was a great place for processions in old Florence. Here stand the church of the _Santissima Annunziata_ and the convent of the Servites, while the Piazza itself is flanked to right and left by arcades originally designed by Brunelleschi. The equestrian statue of the Grand Duke Ferdinand I. was cast by Giovanni da Bologna out of metal from captured Turkish guns. The arcade on the right, as we face the church, with its charming medallions of babies in swaddling clothes by Andrea della Robbia, is a part of the Spedale degli Innocenti or Hospital for Foundlings, which was commenced from Brunelleschi's designs in 1421, during the Gonfalonierate of Giovanni dei Medici; the work, which was eloquently supported in the Council of the People by Leonardo Bruni, was raised by the Silk-merchants Guild, the Arte di Por Santa Maria. On its steps the Compagnacci murdered their first victim in the attack on San Marco. There is a picturesque court, designed by Brunelleschi, with an Annunciation by Andrea della Robbia over the door of the chapel, and a small picture gallery, which contains nothing of much importance, save a Holy Family with Saints by Piero di Cosimo. In the chapel, or church of Santa Maria degli Innocenti, there is a masterpiece by Domenico Ghirlandaio, painted in 1488, an Adoration of the Magi (the fourth head on the left is the painter himself), in which the Massacre of the Innocents is seen in the background, and two of these glorified infant martyrs, under the protection of the two St. Johns, are kneeling most sweetly in front of the Madonna and her Child, for whom they have died, joining in the adoration of the kings and the _gloria_ of the angelic choir.
