There are a number of characters reflected, mythological characters, reflected in each of the books because of the basic theme, if you will, of the books, that information becomes distorted over distance or time... you cannot know the truth of an event the further you get from it. These people are supposed to be the source of a great many of our legends or myths, but what they actually did bears little resemblance to the myth. That is the conceit, that time has shifted these actions to other people, perhaps compressing two people into one or dividing one into three as far as their actions go so Rand has bits of Arthur and bits of Thor and bits of other characters and so does Mat and so does Nynaeve, and so do others. And yes Mat does have some bits of Odin, but not exclusively. He has bits of Loki and bits of Coyote and of the Monkey King.
