Odin.

Odin is a widely revered god in Norse mythology and Germanic paganism. Most surviving information on Odin comes from Norse mythology, but he figures prominently in the recorded history of Northern Europe. This includes the Roman Empire's partial occupation of Germania, the Migration Period and the Viking Age. Consequently, Odin has hundreds of names and titles. Several of these stem from the reconstructed Proto-Germanic theonym Wōðanaz, meaning "lord of frenzy" or "leader of the possessed", which may relate to the god's strong association with poetry.
