"Baccio" is an abbreviation of Bartolomeo, and "d'Agnolo" refers to Angelo, his father's name. He started as a wood-carver, and between 1491 and 1502 did much of the decorative carving in the church of Santa Maria Novella and the Palazzo Vecchio in Florence. Having made his reputation as a sculptor he appears to have turned his attention to architecture, and to have studied at Rome, though the precise date is uncertain; but at the beginning of the sixteenth century he was engaged with the architect Simone del Pollaiolo in restoring the Palazzo Vecchio, and in 1506 he was commissioned to complete the drum of the cupola of the church of Santa Maria del Fiore. The latter work, however, was interrupted on account of adverse criticisms from Michelangelo, and it remained unexecuted.
Baccio d'Agnolo also planned the Santo Spirito. His studio was the resort of the most celebrated artists of the day, Michelangelo, Andrea Sansovino, the brothers Antonio da Sangallo the Elder and Giuliano da Sangallo and the young Raphael. He died at Florence in 1543, leaving three sons, all architects, the best-known being Giuliano D'Agnolo.
