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.
Leonardo da VinciThe lie is so vile, that even if it were in speaking well of godly things, it would take off something from God's grace; and Truth is so excellent, that if it praises but small things they become noble.
Leonardo da Vinci
