Leonardo da Vinci – The Foetus in the Womb (c 1510-13)
Leonardo expresses the human condition in a nutshell – indeed, his rendition of the womb resembles an opened horsechestnut casing. Inside is the beginning of us all laid bare. Five hundred years ago, this artist and scientist could portray the human mystery with a wonder that is not religious but biological he holds up humanity as a fact of nature. It is for me the most beautiful work of art in the world.
