This is probably one of the most famous archeological mysteries of all time, this disc was found on the island of Crete in 1908. It’s made of bronze and has plenty of small characters inscribed on it in a clockwise pattern.

Despite all the technology and information we have at our disposal, no one knows where it came from or what it says. Some say it’s fake, while other swear by its authenticity. Until a translation key, much like the rosetta stone, is discovered, we’ll never know.
