MIMIR

In Norse mythology, Mimir or Mimer was a giant god of wisdom and knowledge. He dwelt by the ash-tree Yggdrasil, and owned the fountain of wisdom from which he allowed Odin to drink on his pledging an eye. Mimir, sent by Odin as a hostage, was beheaded by the Vanir. The head was subsequently embalmed by Odin and consulted as an oracle.
