4: “Sections of a Man’s Head Showing the Anatomy of the Eye, etc.” by Leonardo da Vinci, around 1500

A.E. Popham, The Drawings of Leonardo da Vinci (London: Random House, 1946), 227.

Drawing of a side view of a man’s head. This drawing is quite different from the other anatomical drawings, in that da Vinci really seems to cut into and provide layers around the skull to show where the eyes are. In the bottom right, we can see some very detailed spacing and measurements.
