Medieval artworks, illuminations, and marginalia include some really weird scenes that defy modern interpretation. However, the world is full of people who will give it a try, just to be funny. If you are one of them, you’ll be intrigued by the Medieval Meme Generator. Choose an image from a collection from the KB National Library of the Netherlands, read about the image to find its intended meaning, and add your own punch line. There are 15 images now available (some may be considered NSFW), and they will be switched out every three months or so. Even if you don’t want to create jokes with them, exploring the history of these really weird images is a good use of your free time. -via Nag on the Lake
