Leonardo da Vinci was a Renaissance genius. Not only did he paint masterpieces of art, but he was an obsessive scientist and inventor, dreaming up complex machines centuries ahead of his time, including parachutes, armored tanks, hang gliders, and robots.
Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks – some even 1,700 years before.
In October 2009, a striking portrait of a young woman in Renaissance dress made world news headlines. Originally sold two years before for around $20,000, the portrait is now thought to be an undiscovered Leonardo da Vinci masterwork worth more than $100 million.
