“The beginnings and ends of shadow lie between the light and darkness and may be infinitely diminished and infinitely increased. Shadow is the means by which bodies display their form. The forms of bodies could not be understood in detail but for shadow.”

Italian polymath of the High Renaissance

Leonardo da Vinci was an Italian polymath of the High Renaissance, active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. Born Leonardo di ser Piero da Vinci, he is best known simply as Leonardo. His reputation first rested on painting, but his notebooks made him famous in a broader sense. In them, he set down drawings and notes on subjects ranging from anatomy and astronomy to botany, cartography, painting, and palaeontology. He is widely regarded as a genius who embodied the Renaissance humanist ideal, and his work helped shape European art.
