What ensued may best be reported in the narration which Torrigiano at a later time made to Benvenuto Cellini.
"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, when he was annoying me, I got more angry than usual, and, clenching my fist, I 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." The portraits of Michelangelo prove that Torrigiano's boast was not a vain one.

They show a nose broken in the bridge.

But Torrigiano, for this act of violence, came to be regarded by the youth of Florence with aversion, as one who had laid sacrilegious hands upon the sacred ark.

Cellini himself would have wiped out the insult with blood.
