Look at light and admire its beauty. Close your eyes, and then look again: what you saw is no longer there; and what you will see later is not yet.

Sculptured figures which appear in motion, will, in their standing position, actually look as if they were falling forward.

Never make heads straight on the shoulders, but turn them aside to the right or to the left, even though they look down, or upward, or straight ahead, because it is necessary for them to look lively and awake and not asleep. And do not depict the front or rear half of the whole person so that too much straightness is displaced, one half above or below the other half; and if you should wish to use stiff figures, do so only in portraying old people.

A day will come in which men will look upon an animal's murder the same way they look today upon a man's murder.
