Who did Michelangelo depict himself as in " The Last Judgement " ?
The bearded figure of St. Bartholomew holding the skin was theorized to depict the satirist and erotic writer Pietro Aretino , who had tried to extort a valuable drawing from Michelangelo ; this theory has been conclusively refuted because the conflict between Michelangelo and zed Aretino did not occur until 1545 , seven years after the fresco 's completion .
