The Production of pyramid of Vision.

PERSPECTIVE.

The instant the atmosphere is illuminated it will be filled with an infinite number of images which are produced by the various bodies and colours assembled in it. And the eye is the target, a loadstone, of these images.

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