In 1476 Da Vinci and some other guys were anonymously accused of committing homosexual sex with a male model of his time. Da Vinci was held and questioned quite thoroughly on his sexual life and thoughts, and always insisted that his sex life was nonexistent as befits an artist. He was acquitted and his sexuality has been in question ever since; it was even the subject of a Sigmund Freud book, who maintained that Da Vinci was, in fact, gay.

And for grins and giggles, the beginning of Assassin's Creed 2 (which features Da Vinci as a supporting character) is set in 1476.

This game just looks better and better every day.
