Italian sculptor. He had a typically Tuscan training and he took up in Rome the model of the Florentine public fountain. He took Guglielmo della Porta's position as papal portraitist: he was the sculptor of the bust of Gregory XIII, now in the Staatliche Museen, Berlin. His most important works are: The Winter, one of the decorative statues at the bridge of Santa Trinità in Florence; and the statues of four men for the Fontana delle Tartarughe in Rome (1585). //
