Although the dodecahedrons are mysterious objects, they aren’t rare. There are more than one hundred of these odd artifacts that have been found. Some are made of stone and some are made of bronze, but all are hollow twelve sided devices with small circles. Some dodecahedrons have been found aboard sunken ships which led to the theory that they were some sort of nautical navigation tool. But if that is the case, experts have yet to figure out how they work.
In fact, most people think that the dodecahedrons had another purpose, perhaps a religious one. Still other possible uses are astrological markers, or agriculture tools, or even a means to calibrate water pipes in Roman aqueducts.
