Best Answer - Chosen by Asker:

This is a sketch by DaVinci. It shows the proportions of the ideal human body as they were described by the ancient Roman author Vitruvius. One part is missing so you can't see the fourth side of the square where the body stands.
The purple thing is an addition by someone else. No idea what it stands for.
