He was one of the few whom Michelangelo ever let watch him carve. Years later he wrote:
“I saw Michelangelo at work. He was over sixty and although he was not very strong, yet in a quarter of an hour he caused more splinters to fall from a very hard block of marble than three young masons in three or four times as long. No one can believe it who has not seen it with his own eyes. And he attacked the work with such energy and fire that I thought it would fly into pieces. With one blow he brought down fragments three or four fingers in breadth, and so exactly at the point marked, that if only a little more marble had fallen, he would have risked spoiling the whole work.”
In fact, Michelangelo was past seventy-five and the Frenchman must have chanced into his workshop on one of the very first days of the carving, when, having taken his measurements, Michelangelo pared the “fat” off his block. Otherwise he would not have brought down fragments so large nor worked so recklessly. Michelangelo hated to be watched while he worked, not only because idlers as well as critics made him nervous but because he liked to keep his carving technique a secret. Benvenuto Cellini seems to say he saw him working in the Medici chapel, but he may only have seen the large clay models Michelangelo used there for reference while he carved.
