What's this?

[Recusant]

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.
