A rabbit stands up on its hind legs and decapitates a man, a knight is defeated by a gigantic snail, a nun plucks penises from a tree. These are just some of the strange images, along with various other messages that were left in the margins of many illustrated manuscripts produced during the Middle Ages. Referred to as marginalia, many of the written doodles are funny and give us a glimpse into the lives of the Medieval people who were carrying out what was probably a very tedious job.
