Thoughts on Art and Life is Leonardo da Vinci's tome of sayings and knowledge on life, art, and science. Fans of da Vinci and science alike will marvel at his brilliant writings and his efforts at the creation and understanding of great things. Excerpt: “Begun at Florence in the house of Piero di Braccio Martelli, on the 22d day of March 1508; and this is to be a collection without order, taken from many papers which I have copied here, hoping to arrange them later, each in its place, according to the various subjects treated.”
