On the outlines of cast shadows.

OF SHADOWS WHICH NEVER COME TO AN END.

The greater the difference between a light and the body lighted by it, the light being the larger, the more vague will be the outlines of the shadow of that object.

The derived shadow will be most confused towards the edges of its interception by a plane, where it is remotest from the body casting it.

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