I never really thought about their history. It's one of those things that you just don't think about. Besides, I always assumed it was possibly just a few hundreds years old invention. It didn't occurred to me that there is such a rich history for this little thing. But, I discovered that locks have been around long before the birth of Christ. They are often mentioned both in the old testaments and in the mythology. Once I read that, it made sense to me. I've also learned that there are many types of locks with different shapes, purposes and origins. There is even a lock museum in Terryville, Connecticut. I had no idea there is such a museum. It wouldn't even crossed in my mind.
Also. I saw several other good links that I liked. Below are links for three sites that I enjoyed viewing. The first link is focused on the history, the second one is the museum, and the last two links are from the American Lock Collectors Association. There are a truly many amazing pictures of unique shaped locks. There are even locks that are shaped like animals. They are called Figural Locks.
