От издателя:Most of what we know about Leonardo da Vinci, we know because of his notebooks. Some 6,000 sheets of notes and drawings survive, perhaps one-fifth of what he actually produced. With an artist's eye and a scientist's curiosity, he recorded in these pages his observations on the movement of water and the formation of rocks, the nature of flight and optics, anatomy, architecture, sculpture, and painting.
