A Roman "what's-it?"

We know it's Roman, but what the heck is it? That's the question being asked by archaeologists about a Roman dodecahedron dating from the 2nd-3rd century and found throughout Roman Europe. (photo)

The twelve-sided, bronze artifact has been described as "war weapon, a candlestick, a child’s toy, a weather gauge, an astronomical instrument, and a religious symbol," but experts can't seem to agree on its purpose. Most dodecahedrons have been found in France, Germany and Switzerland.
