General Raytracing

Leonardo da Vinci (1452 – 1519)
It is impossible that the eye should project from itself, by visual rays, the visual virtue, since, as soon as it opens, that front portion of the eye which would give rise to this emanation would have to go forth to the object and this it could not do without time. And this being so, it could not travel so high as the sun in a month's time when the eye wanted to see it. And if it could reach the sun it would necessarily follow that it should perpetually remain in a continuous line from the eye to the sun and should always diverge in such a way as to form between the sun and the eye the base and the apex of a pyramid.
