The figure of Leonardo da Vinci united both the arts and the sciences. On the one hand he was a painter and skilled draftsman, and on the other an inventor and tireless researcher. A legend in his own time, Leonardo was accused of witchcraft by others jealous of his skills, who saw him as some sort of wizard. He was a prolific inventor, and many of his futuristic designs are still with us today, such as the contact lens and the armored vehicle.
