In Norse mythology Odin is the highest of the gods, presiding over war, wisdom and death. He is the husband of Frigg and resides in Valhalla, where warriors go after they are slain. He is usually depicted as a one-eyed older man, carrying two ravens on his shoulders who inform him of all the events of the world. At the time of Ragnarök, the final battle, it is told that he will be killed fighting the great wolf Fenrir.
As an English name it was not used until after the Protestant Reformation. It was utilized by George Eliot for the title character in her novel Silas Marner (1861).
