Do you have any interesting ideas about renaissance painters or paintings ? unknown facts?

There are several periods called "renaissance" so you have to say which one. And anything you learn about such paintings is interesting if you happen to be interested. For example if you look up pictures of Louis XIV he almost always has his legs exposed. I had assumed he was just a pervert, but then I found out he considered dancing to be a badge of manliness and showed off his dancer's legs as often as possible. He would make courtiers dance to decide some legal charge they had against each other.
