She came to Heorot. There, inside the hall,
Danes lay asleep, earls who would soon endure
a great reversal, once Grendel’s mother
attacked and entered. Her onslaught was less
only by as much as an amazon warrior’s
strength is less than an armed man’s
when the hefted sword, its hammered edge
and gleaming blade slathered in blood,
razes the sturdy boar-ridge off a helmet.
– Beowulf, Seamus Heaney (trans.)
Lines 1279-1287: Peace in the hall of the communal Danes is disturbed when the hell-dame Grendel’s mother attacks.
