Like nobody before or since, Leonardo da Vinci united both the arts and the sciences. He was not only a painter and skilled draftsman, but also an inventor and tireless researcher. His art, including the Mona Lisa and The Last Supper, remain classics of Western civilization. And though he lived 500 years ago, many of his futuristic ideas, such as the contact lens and the armored vehicle, are still with us today. Leonardo da Vinci and the Pen That Drew the Future tells the story of the greatest thinker of the Renaissance.
