This master piece is probably known by everyone, hence I guess no-one knows it has a name! It was drawn around 1492 by Leonardo da Vinci and is about architecture and the proportions of the human body.

The drawing is now located in the Accademia di Belle Arti in Venice, Italy. There is a nice article about “The Vitruvian Man and the plannng of temples”
