In this
article about Ken Burns's Leonardo documentary, I came across this section:
“He’s not tortured like Michelangelo. He’s not the striving kid that Raphael is. He’s not the murderer Caravaggio. He’s just a theatre director, wears gaudy clothes, is a musician, wants to sing, is the life of every party. It was important to try to understand that this is not going to fit into your classic cut-off-your-ear portrait of a tortured artist.”
I rooted for it to mention Donatello, but it never happened.
