One of the principal Norse gods. A war god from earliest times, Odin appeared in Scandinavian heroic literature as the protector of heroes. Fallen warriors were believed to join him in Valhalla. Odin was the great magician among the gods and was associated with runic writing. His eight-legged horse, Sleipnir, could gallop through the air and over the sea. Odin was usually depicted as a tall old man with a flowing beard and only one eye (the other he gave in exchange for wisdom); he wore a cloak and a wide-brimmed hat and carried a spear. The wolf and the raven were dedicated to him.
