From Valfather’s pledge.
Understand ye yet, or what?
This myth was given in connection with Ygdrasil, but it is repeated here to shed a ray of light upon the character of Odin, and in this wise Mimer is brought into a clearer sunlight also.
In regard to Odin’s speaking with Mimer’s head, we have the following passage in the lay of Sigdrifa:
On the rock he[[40]] stood
With edged sword,
A helm on his head he bore.
Then spake Mimer’s head
Its first wise word,
And true sayings uttered.
