torrigiano

It is said that Torrigiano, who had struck up a friendship with Michelangelo, then became jealous on seeing him more honoured than himself and more able in his work. At length Torrigiano started to mock him, and then he hit him on the nose so hard that he broke and crushed it and marked Michelangelo for life. Because of this, Torrigiano, as I describe elsewhere, was banished from Florence.

From Giorgio Vasari’s The Lives of the Artists (1550)
