Wolf plays an important role in Norse mythology, because wolf is closely related to Odin. There are at least five wolves in Norse mythology, which are Odin’s wolves Geri and Freki; Fenrir, a monstrous wolf who swallows Odin; as well as Fenrir’s sons Sköll and Hati. And at present, wolf is an important element in Viking culture.
The Norse tree of life is a large ash tree named Yggdrasil the world tree, which connects the Nine Worlds and is the center of the cosmos. Yggdrasil is also the tree where it's said that Odin sacrificed himself. Yggdrasil represents the cycle of life, death and rebirth.
