Nor did the creature keep him waiting
but struck suddenly and started in;
he grabbed and mauled a man on his bench,
bit into his bone-lapping, bolted down his blood
and gorged on him in lumps, leaving the body
utterly lifeless, eaten up
hand and foot.
– Beowulf, Seamus Heaney (trans.)
Lines 738-744: Grendel doesn’t just murder but cannibalises and consumes his victims.
