Popular Medieval Memes Explained

We know that medieval art can be really weird. It's one thing to find a random jousting snail or an ugly baby Jesus, but when those things happen over and over, you start to wonder what caused those trends.

So it's only fitting that they have become memes all over again in the 21st century!
