Norse mythology
Central to accounts of Norse mythology are the plights of the gods and their interaction with various other beings, such as with the jötnar, who may be friends, lovers, foes or family members of the gods. Numerous gods are mentioned in the source texts. As evidenced by records of personal names and place names, the most popular god among the Scandinavians during the Viking Age was Thor, who is portrayed as unrelentingly pursuing his foes, his mountain-crushing, thunderous hammer Mjölnir in hand. In the mythology, Thor lays waste to numerous jötnar who are foes to the gods or humanity, and is wed to the beautiful, golden-haired goddess Sif.
