I have a couple of questions about the artist known as Leonardo Da Vinci.?

Da Vinci painted... but he also is credited as a scientist. He invented scissors! He made plans for an airplane and a tank. He used egg tempera and experimented with other types of paint like in The Last Supper- much of it flaked off... He was alive during the Renaissance... he was gay and jailed for it- rival of Michelangelo- he helped make advances in medicine due to his drawings of cadavers- he was constantly learning- he took more than 3 yrs. to paint Mona Lisa- most famous ptg. in the world
