To me it’s Michelangelo, the guy just seemed to be an artistic prodigy of sorts, it always amazes me how the artists of those time periods could create incredible, detailed works in vastly different mediums. I mean if you are a fantastic painter, that doesn’t mean you are a great sculptor, etc. Michelangelo seemed to be able to do it all.
From what Iv’e read he seemed pretty asocial and supposedly wasn’t the most hygienic of people and I know he’s been posthumously diagnosed with things like Asperger’s though it’s impossible to really say. Leonardo had many varied interests and he was definitely the guy it sounds like it would have been more fun to grab a beer with and have a discussion.
