Today's Fact
Everybody knows the All-Father paid an eye for wisdom; almost nobody follows the eye afterward.
As retold in Thor Vol. 1 #274 (1978), Odin went to Mimir and surrendered his right eye in exchange for knowledge of how to forestall Ragnarok. But Marvel did not leave the eye floating in the well: in the Eternals Saga that followed, the lost Eye of Odin had grown enormous and become sentient in its own right, a living oracle that allowed Thor exactly one question.
Thor used his single question well. The Eye answered by carrying him backward through time, showing him a true Ragnarok that had already happened before his birth — an earlier cycle in which another Thor died fighting the Midgard Serpent and only nine gods survived. The All-Father's discarded body part had become the sole surviving witness to a history Asgard itself had forgotten.
There is a bleak joke built into the arrangement: Odin traded the eye to learn how doom could be delayed, and the eye ended up knowing things even Odin no longer did. Wisdom, in Asgard, apparently appreciates in value once it is severed from the king who paid for it.
Why It's Obscure
The sacrifice is mythology's most famous bargain; the eye's second career as a character is pure Marvel, and pure footnote.
