Leonardo da Vinci has many great accomplishments, though few argue his contributions to the Da Vinci Code outweigh all else. The painter, inventor, and just plain geek-extraordinaire created some of the most famous paintings in history, the Mona Lisa and the Last Supper, and contributed to the studies of aviation, engineering, and even plate tectonics. Sure, a casual glance might make these revolutionary and ahead-of-their time predictions seem important, but when you think about how many copies the Da Vinci Code has sold compared to Da Vinci’s own works, the lazy guy only has 15 paintings in existence, then you really see who’s going to stand the test of time.
