Vitruvian Man by Da Vinci _ Pang Nian Ching1201143

This is Leonardo’s famous drawings of the Vitruvian proportions of a man’s body first standing inscribed in a square and then with feet and arms outspread inscribed in a circle provides an excellent early example of the way in which his studies of proportion fuse artistic and scientific objectives.

 In my opinion, it is a drawing that showing perfect interest in proportion. And in this picture represents a cornerstone of Leonardo's attempts to relate man to nature. Leonardo is using square and circle to draw the whole body proportion and clear to draw it. He is using square to accurate the human arms positions, and using circle to make sure the legs proportion.
