In WoT, the tinkers are known by another name, the Tuatha'an, the travelling people. In Irish mythology the Tuatha De Danann are, among other things, supposed to have brought druidry and chariots to Ireland, as well as being prominent Pagan Gods. Don't know if it means anything but I thought it was interesting anyway. Here's the link to the wikipedia sight - http://en.wikipedia.org/wiki/Tuatha_D%C3%A9_Danann - have a look

Yep, early European mythology plays a great part in RJ's writings. The Tuatha'an, the Finns, Mat=Odin, Rand bears great similarities to Tyr... the list goes on and on.
