Leonardo da Vinci was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, theorist, engineer, scientist, sculptor and architect. While his fame initially rested on his achievements as a painter, he also became known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo's genius epitomized the Renaissance humanist ideal, and his collective works compose a contribution to later generations of artists rivaled only by that of his younger contemporary and fellow founder of the High Renaissance, Michelangelo.
