“When one considers the evidence for medieval chastity belts, as Classen did in his book The Medieval Chastity Belt: A Myth-making Process, it becomes apparent pretty quickly that there’s not much of it. First of all, there aren’t actually all that many pictures of or accounts of using chastity belts, and even fewer physical specimens. And the few book-length works on the topic rely heavily on each other and all cite the same few examples.
"You have a bunch of literary representation, but very few historical references to a man trying to put a chastity belt on his wife,” says Classen. And, any literary reference to a chastity belt is likely either allegorical or satirical.“
