Amateur archaeologists in eastern England found something super weird while digging through old Roman stuff: a bronze object with 12 flat faces, about the size of a fist. It turned out to be a Roman dodecahedron, an object that's been confusing experts for centuries. Since the first one was found in 1739, around 130 have been discovered all over Northern and Western Europe. Despite being from Roman times, no one knows what they were used for—there's nothing written about them or any pictures of them in ancient texts. This mystery just gives us more questions than answers, and it's not the only one of its kind!
