A Roman Dodecahedron is a small hollow object made of bronze or stone, with a dodecahedral shape: twelve flat pentagonal faces, each face having a circular hole of varying diameter in the middle, the holes connecting to the hollowed-out center. Roman dodecahedra date from the 2nd or 3rd centuries CE. These Roman dodecahedrons, have puzzled archaeologists. More than 100 of them have been discovered across Europe, and no one has yet found conclusive proof of what they were actually meant for. According to some, they were used as dice or lucky charms; other theories, meanwhile, suggest that they were utilized to measure the trajectory of projectiles or even as devices to help with the weaving of gloves.
