Leonardo da Vinci, a prominent figure of the High Renaissance, was an Italian polymath excelling in painting, drawing, engineering, science, theory, sculpting, and architecture. While renowned initially for his paintings, his notebooks, containing drawings and notes on diverse subjects such as anatomy, astronomy, botany, cartography, painting, and palaeontology, have also contributed significantly to his fame. Considered a genius embodying the Renaissance humanist ideal, his work has influenced generations of artists, rivaled only by his contemporary, Michelangelo.
