Roman Dodecahedrons
Going back to the 3nd and 3rd centuries AD, these still puzzle archeologists. They range between 3cm to 10cm, and it’s in the shape of a pentagon, with large holes and knobs on each point.
Found all over Europe, there are many theories over what these are – whether they’re a measuring device, or something religious. In any case, based on where they were found within the ruins of Roman homes, they were extremely valuable and treasured.
