Question

How does this painting called Ginevra De' Benci show that Leondardo Da Vinci is a Renaissance man, like what techniques does he use that they used in the renaissance time?
Here's a picture of the painting: http://www.google.co.uk/imgres?q=ginevra+de+benci&um=1&hl=en&client=safari&sa=N&rls=en&biw=1099&bih=991&tb

Answer 1

Frankly? It doesn't. Sure it is painted in a style typical to the renaissance period. But that does not make the man who painted it a renaissance man.

http://en.wikipedia.org/wiki/Polymath
A renaissance man is another term for a polymath. Or more commonly "Jack of all trades" and master in all as well. So just this painting makes him a renaissance painter. All the other stuff he did like anatomist, architect, inventor on top of that makes him a renaissance man.
