“This Buonarroti and I used, when we were boys, to go into the Church of the Carmine, to learn drawing from the chapel of Masaccio. It was Buonarroti’s habit to banter all who were drawing there; and one day, among others, when he was annoying me, I got more angry than usual, and clenching my fist, gave him such a blow on the nose, that I felt bone and cartilage go down like biscuit beneath my knuckles; and this mark of mine he will carry with him to the grave.”
