The heavens often rain down the richest gifts on human beings, but sometimes they bestow with lavish abundance upon a single individual beauty, grace and ability, so that whatever he does, every action is so divine that he distances all other men, and clearly displays how his greatness is a gift of God and not an acquirement of human art. Men saw this in Leonardo. (Vasari, Lives of the Most Excellent Painters, Sculptors, and Architects)
Leonardo: from Florence to Milan
Having until now sufficiently studied and examined the experiments of all those who claim to be experts and inventors of war machines, and having found that their machines do not differ in the least from those ordinarily in use, I shall make so bold, without wanting to cause harm to anyone, as to address myself to Your Excellency to divulge my secrets to him, and offer to demonstrate to him, at his pleasure, all the things briefly enumerated below.
In time of peace, I believe I am capable of giving you as much satisfaction as anyone, whether it be in architecture, for the construction of public or private buildings, or in bringing water from one place to another. Item, I can sculpt in marble, bronze or terracotta; while in painting, my work is the equal of anyone’s.

Leonardo’s Death and the Changing Status of the Artist
Finally, having grown old, he remained ill many months, and, feeling himself near to death, asked to have himself diligently informed of the teaching of the Catholic faith, and of the good way and holy Christian religion; and then, with many moans, he confessed and was penitent; and although he could not raise himself well on his feet, supporting himself on the arms of his friends and servants, he was pleased to take devoutly the most holy Sacrament, out of his bed. The King, who was wont often and lovingly to visit him, then came into the room; wherefore he, out of reverence, having raised himself to sit upon the bed, giving him an account of his sickness and the circumstances of it, showed withal how much he had offended God and mankind in not having worked at his art as he should have done. Thereupon he was seized by a paroxysm, the messenger of death; for which reason the King having risen and having taken his head, in order to assist him and show him favour, to then end that he might alleviate his pain, his spirit, which was divine, knowing that it could not have any greater honour, expired in the arms of the King.
