Mimir
;)
in Germanic mythology, was a wise god sent by the Aesir to the Vanir in order to seal the peace after these two branches of the divine family tired of war. Because the Vanir felt that they had been cheated, they cut off Mimir's head and sent it back to the Aesir. Odin, however, smeared the severed head with herbs so that it would never rot. He then recited a charm over it to restore its power of speech. Later, Mimir's head was placed by Odin to guard a magic well under the root of the cosmic tree Yggdrasil. To gain Mimir s wisdom, which comprised 'many truths unknown to any other person', Odin gave one of his eyes for permission to drink at the well.
