Gram in his hand, and golden spurs on his heels; then leapt Grani
into the fire when he felt the spurs; and a mighty roar arose as
the fire burned ever madder, and the earth trembled, and the
flames went up even unto the heavens, nor had any dared to ride
as he rode, even as it were through the deep mirk.

But now the fire sank withal, and he leapt from his horse and
went into the hall, even as the song says --

"The flame flared at its maddest,
Earth's fields fell a-quaking
As the red flame aloft
Licked the lowest of heaven.
Few had been fain,
Of the rulers of folk,
To ride through that flame,
Or athwart it to tread.

"Then Sigurd smote
Grani with sword,
And the flame was slaked
Before the king;
Low lay the flames
Before the fain of fame;
Bright gleamed the array
That Regin erst owned.

Now when Sigurd had passed through the fire, he came into a
certain fair dwelling, and therein sat Brynhild.
