On this episode, we try to unravel the tale of the European phenomenon of rat kings. As the story goes, long ago a wise old rat who wanted to be the king of all the rats made the lesser rats form a mountain. He climbed up to the top, and sat there, demanding respect and adoration from the other rats. Unfortunately for those other rats, they had been using their tails to hold onto each other and became tangled up together. In the 1500s, this tale gave rise to the term “rat king.” But where did this story come from?
