Leonardo Da Vinci is the archetype of a Rennaisance man—artist, mathematician, sculptor, scientist, writer, and more. As an artist, Leonardo produced a very small sample of great work that included the Mona Lisa and the Last Supper. Leonardo was a prolific sketcher, producing more than 13,000 pages, which are arguably his greatest legacy.
Within his sketchbooks, Leonardo thinks scientifically and creatively. We see sketches of futuristic devices, detailed drawings of human anatomy, postulations on plate tectonics, observations about diet, exercise, and heart disease. We see sketches of weapons, flowers, soldiers, flying machines, horses, and more. Some sketches serve as wireframes for statues and bridges, while other are early renditions of paintings. For Da Vinci, his sketches were his visual thoughts.
