But although Odin was now all-wise, he was sad and oppressed, for he had gained an insight into futurity, and had become aware of the transitory nature of all things, and even of the fate of the gods, who were doomed to pass away. This knowledge so affected his spirits that he ever after wore a melancholy and contemplative expression.
To test the value of the wisdom he had thus obtained, Odin went to visit the most learned of all the giants, Vafthrudnir, and entered with him into a contest of wit, in which the stake was nothing less than the loser’s head.
“Odin rose with speed, and went
To contend in runic lore
With the wise and crafty Jute.
To Vafthrudni’s royal hall
Came the mighty king of spells.”
Vafthrudni’s-mal (W. Taylor’s tr.).
Odin and Vafthrudnir
On this occasion Odin had disguised himself as a Wanderer, by Frigga’s advice, and when asked his name declared it was Gangrad. The contest of wit immediately began, Vafthrudnir questioning his guest concerning the horses which carried Day and Night across the sky, the river Ifing separating Jötun-heim from Asgard, and also about Vigrid, the field where the last battle was to be fought.
