Baccio da Montelupo (1469 - 1523(?)), born Bartolomeo di Giovanni d'Astore dei Sinibaldi, was a sculptor of the Italian Renaissance. He is the father of another Italian sculptor, Raffaello da Montelupo. Both father and son are profiled in Vasari's Le Vite delle più eccellenti pittori, scultori, ed architettori (or, in English, Lives of the Most Excellent Painters, Sculptors, and Architects).
Born into a family of modest social conditions in Montelupo Fiorentino, he moved at eighteen to Florence and pursued the study of sculpture, attending the "scuola" of Bertoldo di Giovanni, founded in the gardens of Lorenzo de' Medici and attended by other young sculptors including Michelangelo, Giovanni Francesco Rustici, and Jacopo Sansovino.
Baccio received his first important commission from the friars of the Basilica of San Domenico in Bologna, for a "Compianto" (lamentation scene), a series of terracotta statues (c. 1495). He then returned to Florence where he created several wooden Crucifixes: at the Basilica di San Lorenzo and San Marco, both in Florence, the Badia di SS. Flora e Lucilla in nearby Arezzo, and the church of San Martino in the Florentine municipality of Lastra a Signa.
In Bologna, Baccio created 12 busts of the Apostles in terracotta (now in the Cathedral of Ferrara).
