Sculptor, born Florence, Italy, c.1386;died there, 1466. He is considered the founder of modern sculpture, his work being the first to combine realism with classic excellence. Among his earliest statues were those for the exterior of the church of Or San Michele in Florence, including the well-known "Saint George," now in the Bargello, where a hall is given up to his work. In 1434 he executed the bronze "David," also in the Bargello, for Cosimo de' Medici. With Michelozzo he designed the tomb of John XXIII in the baptistery of Florence. For the Duomo he did the choir-loft with the beautiful reliefs of singing and dancing boys, a favorite subject with him. In Padua is his bronze equestrian statue of Gattamelata.
