One of the most gifted men of the Renaissance, I was an architect, a painter, a musician, and a mathematician.
I am falsely credited with the invention of the "camera obscura."
My constant contention was that mathematics was the common ground of art and the sciences.
I was one of the first to formulate the laws of perspective, especially relative to painting styles.
Finally, I wrote one of the first books on cryptography.
