I don't think the "knitting tool" hypothesis is conclusive. Some of those dodecahedrons are only about 4 centimeters tall (1.5 inches). Seems unlikely that they were knitting gloves for infants (or toddlers for that matter). Some of them are made of stone and solid as well--would not work for the purpose. Then there are the smaller versions made of gold that were found in Asia.

Similarly enigmatic ancient objects: the carved stone balls from the British Isles.

Damn! Spoil sport! 

Yeah, though there's no saying that they weren't used by innovative Gauls to make gloves.

12 gods of Greece, maybe.
Roman's adopted Greek gods and changed their names.

Is a D12 from before it was cool... Which, let's face it, it never actually was.

The Asmo is a nerd though, and that is good enough for the Asmo.
