The God of Norse Mythology: Odin
Odin was the god of thinking and reasoning. He lived in Asgard, which was home to all the Norse gods. His devotees included the berserkers. The fourth day of the week, Wednesday, was named after Odin, though, weirdly, it is supposed to stand for the day of Mercury. The confusion arose from the differing interpretations of the German word for Odin, Woden.
