Leonardo da Vinci was a 15th century Italian polymath whose areas of interest included painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. Some of his most famous works include The Last Supper, the Mona Lisa, and the Virgin of the Rocks. He apprenticed under the artist Andrea del Verrocchio beginning at age 15 and left the workshop at age 21. Many of Leonardo's inventions, including designs for tanks, helicopters, and parachutes, were far ahead of their time.
