It's very interesting the video about "La Gioconda". It's amazing how Leonardo da Vinci has divided the body in a lot of symetrycal parts. At first it seems like it's a normal picture but if you divide the body like in the video you can see how many symetrical relations have each part towards the others.
Yes, you´re right. Actually, I think that MonaLisa is not a gorgeus woman, in fact, I believe is a little....boring, but it´s true how the divine proportion is present in the picture.
