Odin is the oldest of the gods; Buri's grandson, son of Bestla and Bor.
Hung there for nights full nine;
With the spear I was wounded, and offered I was
To Odin, myself to myself,
On the tree that none may ever know
What root beneath it runs.
Odin is the Norse god of wisdom, especially the occult wisdom of seers and sorcerers. He was the patron and the divine prototype of seers and magicians, especially those who (like shamans in Arctic Europe and Asia in modern times) undergo terrifying initiations and communicate with other worlds in ecstasies and mediumistic trances (Simpson 1971: 215).
Odin himself is a shaman and necromancer who obtains answers from the wisest of the dead. His continual search for occult knowledge lead him to trade one eye to Mimir for a drink from the Well of Wisdom. Mimir is the keeper of the fountains of knowledge and wisdom. His remaining eye symbolizes the all-seeing Sun; the eye in Mimir's well symbolizes the full Moon.
He hears all tidings since the two ravens Hugin and Munin provide him with all tidings.
Thus, Odin is the most learned of all the Norse gods. In this field he is connected to the Greek god Apollo who is the god of seers. Nevertheless, Odin is rater the keeper of magical knowledge. Whereas, Apollo is rather the patron of scientific knowledge. Furthermore, Apollo is connected to the fair and beautiful of the arts. Whereas, Odin is connected to the dark and dangerous powers.
Generally, Odin is more often compared to the Greek god Zeus because he is the godfather of all Norse gods.
