The story goes
that as the pair struggled, mead-benches were smashed
and sprung off the floor, gold fittings and all.
Before then, no Shielding elder would believe
there was any power or person on earth
capable of wrecking their horn-rigged hall
unless the burning embrace of a fire
engulf it in flame.

Beowulf, Seamus Heaney (trans.)

Lines 774-781: Beowulf’s wrestling contest with Grendel wreaks more destruction than anyone had ever thought possible. Beowulf is depicted with almost superhuman strength.
