On the proportion of light and shade.

That portion of an opaque body will be more in shade or more in light, which is nearer to the dark body, by which it is shaded, or to the light that illuminates it.

Objects seen in light and shade show in greater relief than those which are wholly in light or in shadow.

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