he might, and his mind it was that Glam should shrink thereat; but the
thrall lay so hard on Grettir's arms, that he shrank all aback because
of Glam's strength.

Then Grettir bore back before him into sundry seats; but the
seat-beams were driven out of place, and all was broken that was
before them. Glam was fain to get out, but Grettir set his feet
against all things that he might; nathless Glam got him dragged from
out the hall; there had they a wondrous hard wrestling, because the
thrall had a mind to bring him out of the house; but Grettir saw that
ill as it was to deal with Glam within doors, yet worse would it be
without; therefore he struggled with all his might and main against
going out-a-doors.

Now Glam gathered up his strength and knit Grettir towards him when
they came to the outer door; but when Grettir saw that he might not
set his feet against that, all of a sudden in one rush he drave his
hardest against the thrall's breast, and spurned both feet against the
half-sunken stone that stood in the threshold of the door; for this
the thrall was not ready, for he had been tugging to draw Grettir to
him, therefore he reeled aback and spun out against the door, so that
his shoulders caught the upper door-case, and the roof burst asunder,
both rafters and frozen thatch, and therewith he fell open-armed aback
out of the house, and Grettir over him.

Bright moonlight was there without, and the drift was broken, now
drawn over the moon, now driven from off her; and, even as Glam fell,
a cloud was driven from the moon, and Glam glared up against her. And
Grettir himself says that by that sight only was he dismayed amidst
all that he ever saw.
