Michelangelo constructed his persona as an artist. By about 1530 he stops signing "Michelangelo scultore," and just used "Michelangelo." Many aspects of his identity started changing toward the end of the Last Judgement, when he met Vittoria Colonna. He apparently cleaned himself up, bought new clothing, and cultivated the manners of a gentleman. This is interesting because of how physical marble carving is. There are portraits of Michelangelo wearing a turban to catch sweat and marble dust, but that kind of portrait only exists before the 1530s. After that you see him dressed like a nice gentleman in black velvet, so he really did a great deal to refine his biography.

Vasari adds that Pietro then fled Florence for fear of what the ruler Lorenzo might do, and that would place the latest date for the mishap as 1492, when Lorenzo de’ Medici died.
