> DaVinci painted so meticulously that his works have hundreds of layers of paint that are thinner than a strand of hair. DaVinci had really bad technique and couldn't help but endlessly fiddle with his paintings. Many of his paintings never saw the light of day because he ruining them and never finished them. The Last Supper that we know and love was actually a superior copy made by one of his proteges because his original fresco fell apart after a few years owing to his "innovative techniques" - he painted on dry plaster because he took way too long on it. DaVinci was wonderfully imaginative and a very unique artist, but I don't think his reputation has been fully earned by his achievements.
