Haustlong Hrungnir Fight

And this is something that is taboo, throwing whetstones across a
room, for then the whetstone in Thor’s head stirs. Thiodolf of
Hvinir has composed a passage based on this story in Haustlong.
It says there:

Also can be seen on the circle [of the shield], O cave-fire-
[gold-]tree [man], how the terror of giants [Thor] made a
visit to the mound of Griotun. The son of Iord drove to the
game of iron [battle] and the moon’s way [sky] thundered
beneath him. Wrath swelled in Meili’s brother [Thor].

All the hawks’ sanctuaries [skies] found themselves burning
because of Ull’s stepfather, and the ground all low was
battered with hail, when the goats drew the temple-power
[Thor] of the easy-chariot forward to the encounter with
Hrungnir. Svolnir’s widow [Iord, earth] practically split
apart.

Baldr’s brother [Thor] did not spare there the greedy enemy
of men [Hrungnir], Mountains shook and rocks smashed;
heaven above burned. I have heard that the watcher
[Hrungnir] of the dark bone [rock] of the land [sea] of
Haki’s carriages [ships] moved violently in opposition when
he saw his warlike slayer.

Swiftly flew the pale ring-ice [shield] beneath the soles of the
rock-guarder [giant]. The bonds [gods] caused this, the
ladies of the fray [valkyries] wished it. The rock-gentleman
[giant] did not have to wait long after that for a swift blow
from the tough multitude-smashing friend [Thor] of
hammer-face-troll [Miollnir],

The life-spoiler of Beli’s bale-troops [giants] made the bear
[giant] of the noisy storms’ secret refuge [mountain fastnes-
ses] fall on the shield-islet. There sank down the gully-land
[mountain] prince [giant] before the tough hammer and the
rock-Dane-breaker [Thor] forced back the mighty defiant
one.

And the hard fragment of the whetstone of the visitor
[giant] of the woman of Vingnir’s people [the race of giants]
whizzed at ground’s [earth, Iord’s] son into his brain-ridge,
so that the steel-pumice [whetstone] still stuck in Odin’s
boy’s skull, stood there spattered with Eindridi’s [Thor’s]
blood.

Until ale-Gefiun [Groa] began to enchant the red boaster of
being rust’s bale [whetstone] from the inclined slopes of the
wound-giving god’s hair. Clearly I see these deeds on
Geitir’s fence [the shield], I received the border’s moving
cliff [shield] decorated with horrors from Thorleif.

Then Ægir said: ‘Hrungnir seems to me to have been very
mighty. Did Thor achieve any greater exploit in his dealings with
trolls?’
