Christopher Columbus, by Theodore de Bry ca. 1590
Surprisingly, no one really knows or agrees on what 13th Century explorer Christopher Columbus [1451-1506] actually looked like. This image is by Theodore de Bry [1528-1598], who was at least alive at a time when he could compare notes with Columbus' children.
This copy of the image comes from the Professor Carmichael's Cabinet of Curiosities website, where a large number of such images are compared to show how much the idea of Columbus' appearance has varied [Link Here].
