On the proportion of light and shade.

OF PAINTING.

The outlines and form of any part of a body in light and shade are indistinct in the shadows and in the high lights; but in the portions between the light and the shadows they are highly conspicuous.

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