Thor, also known as the Thunderer, was considered to be a son of Fjorgyn (Jord) and Odin by some, but among many tribes Thor actually supplanted Odin as the favorite god. He is considered to be the protector of all Midgard, and he wields the mighty hammer Mjollnir. Thor is strength personified. His battle chariot is drawn by two goats, and his hammer Mjollnir causes the lightning that flashes across the sky. Of all the deities, Thor is the most “barbarian” of the lot; rugged, powerful, and lives by his own rules, although he is faithful to the rest of the Aesir. The day Thursday (Thorsdaeg) is sacred to him.
