Background
On purpose, Robert Jordan puts bits and pieces of myths and legends from all over our world into his Wheel of Time fantasy novels. Our age is both in the past and in the future, in the Wheel of Time.
The Greek name for the serpent biting its own tail is Ouroboros (uroboros, oureboros, oroborus, auroborus) "devouring its tail". http://www.dragon.org/chris/ouroboros.html http://www.badalijewelry.com/ouroboros-a.htm
The name used in Norse myths for the great serpent biting its tail is Jörmungandr. http://www.dragon.org/chris/ouroboros.htmlhttp://www.badalijewelry.com/ouroboros-a.htm
As in the Wheel of Time fantasy novels, worldwide the Great Serpent ring is a symbol of the cyclic nature of life. The serpent eats its tail to feed itself and stay alive, while at the same time this is killing it. Cleopatra tied the Great Serpent into the ideas of Yin and Yang in her alchemy notes. http://www.dragon.org/chris/ouroboros.htmlhttp://www.badalijewelry.com/ouroboros-a.htmIn the Wheel of Time fantasy books, Yin and Yang are the flame of Tar Valon and the hook of the Dragon.
