Light and shadow with regard to the position of the eye.

[figure]

A body in shadow situated between the light and the eye can never display its illuminated portion unless the eye can see the whole of the primary light.

[Footnote: A stands for corpo (body), B for lume (light).]

Taken from The Notebooks of Leonardo da Vinci edited by Jean Paul Richter, 1880.
