Definition of the nature of shadows.

[figure]

Shadow is the diminution of light by the intervention of an opaque body. Shadow is the counterpart of the luminous rays which are cut off by an opaque body.

This is proved because the shadow cast is the same in shape and size as the luminous rays were which are transformed into a shadow.

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