King Hraudung had two sons, one named Agnar, the other Geirröd. Agnar
was ten, and Geirröd eight winters old. They both rowed out in a boat,
with their hooks and lines, to catch small fish; but the wind drove
them out to sea. In the darkness of the night they were wrecked on the
shore, and went up into the country, where they found a cottager, with
whom they stayed through the winter. The cottager's wife brought up
Agnar, and the cottager, Geirröd, and gave him good advice. In the
spring the man got them a ship; but when he and his wife accompanied
them to the strand, the man talked apart with Geirröd. They had a fair
wind, and reached their father's place. Geirröd was at the ship's
prow: he sprang on shore, but pushed the ship out, saying, "Go where
an evil spirit may get thee." The vessel was driven out to sea, but
Geirröd went up to the town, where he was well received; but his
father was dead. Geirröd was then taken for king, and became a famous
man.

Odin and Frigg were sitting in Hlidskiâlf, looking over all the world.
Odin said, "Seest thou Agnar, thy foster-son, where he is, getting
children with a giantess in a cave? while Geirröd, my foster-son, is a
king residing in his country." Frigg answered, "He is so inhospitable
that he tortures his guests, if he thinks that too many come." Odin
replied that that was the greatest falsehood; and they wagered
thereupon. Frigg sent her waiting-maid Fulla to bid Geirröd be on his
guard, lest the trollmann who was coming should do him harm, and also
say that a token whereby he might be known was, that no dog, however
fierce, would attack him. But that King Geirröd was not hospitable was
mere idle talk. He, nevertheless, caused the man to be secured whom no
dog would assail. He was clad in a blue cloak, and was named Grimnir,
