Michelangelo

Ah, Michelangelo. A man whose talent was as colossal as his ego, and whose personal hygiene was, shall we say, rumored to be less than divine. This was the archetypal brooding artist, a man who feuded with rivals like Leonardo da Vinci and Raphael, and was known for his sharp tongue. Legend has it he once got his nose permanently crooked in a youthful brawl with a fellow student who couldn't handle his jeering. And if you ever got on his bad side, you might just find yourself immortalized in one of his masterpieces. Rumor has it that when a papal official criticized the nudity in "The Last Judgement," Michelangelo painted him into the depths of hell, complete with donkey ears and a serpent for company. Now that's what you call artistic revenge.
