Leonardo da Vinci (1452-1519) was a painter, architect, inventor, and student of all things scientific. His natural genius crossed so many disciplines that he epitomized the term, “Renaissance Man.” Today he remains best known for his art, including two paintings that remain among the world’s most famous and admired, Mona Lisa and The Last Supper. Art, da Vinci believed, was indisputably connected with science and nature. Largely self-educated, he filled dozens of secret notebooks with inventions, observations and theories about pursuits from aeronautics to anatomy. Although he was lauded in his time as a great artist, his contemporaries often did not fully appreciate his genius-the combination of intellect and imagination that allows him to create, at least on paper-such inventions as the bicycle, the helicopter, and an airplane based on the physiology and flying capability of a bat. This artwork is a sculptural version of a self portrait drawing made by da Vinci known as “portrait of a man in red chalk.” This self portrait was made in 1510 when da Vinci would have been about 60.
