Odin is the leader of the Aesir, and god of war, death, poetry, and wisdom. He drinks only wine, and gives any meat he receives to his wolves. Odin has many wives, and many, many children. He appears in almost all Norse stories.
In art, Odin is depicted as an older, grey-beared man with one eye and wearing a blue cloak and a broad-brimmed hat. He usually carries his spear, Gungnir, and wears Draupnir, the magic golden ring. Odin may also have ravens on his shoulders and/or wolves at his feet. He might or might not be sitting on his throne, Hlidskialf.
