Grímnismál

Through an error, King Geirröth tortured Odin-as-Grímnir, a fatal mistake, since Odin caused him to fall upon his own sword.

The work starts out with a lengthy prose section describing the circumstances leading up to Grímnir's monologue.

Henry Adams Bellows suggests that they were added in the 12th or 13th century and based on some sort of narrative tradition regarding the poem.

Frigg then sent her maid Fulla to Geirröth, advising him that a magician would soon enter his court to bewitch him, and saying that he could be recognised by the fact that no dog was fierce enough to attack him.

Shifting from prose to poetry for Odin-as-Grímnir's monologue, Grímnir describes at great length the cosmogony of the worlds, the dwelling places of its inhabitants, and himself and his many guises.

Having learned that he is undone, he rose quickly to pull Odin from the fires, but the sword which he had lain upon his knee slipped and fell hilt down, so that when the king stumbled he impaled himself upon it.

In the 2017 Starz television adaptation of Neil Gaiman's American Gods, the character Mad Sweeney refers to Mr. Wednesday as Grimnir.
