In a body of work that is perhaps unparalleled in history, Leonardo da Vinci's (1452-1519) sketches and copious notes allow us to peer into the mind of a genius.

He was a consummate draftsman and sketch artist who carefully recorded his world and the travels of his mind in mirror-image cursive. A man of unquenchable curiosity spanning an infinite spectrum, he was simultaneously taken with the concepts of grace and geometric structure of the universe.
