The night that Beowulf fought the monster Grendel in the great hall of Heorot is the climactic scene of the Old English poem Beowulf, and one of the great set-pieces of world literature. The episode gathers the central themes of the poem — the heroic ideal, the Christian understanding of evil, the gift-economy of the Germanic north, and the mortality of even the greatest man — and the night of the fight is presented with a slow, ritual dignity that is unmatched in medieval English literature. The episode has also been the model for many later monster-fights in English fiction.
The Hall of Heorot
The setting is the great hall of Heorot, “the Hart.” Hrothgar, the Danish king, has built the hall to be the largest of its kind in the northern world, with towers reaching to the clouds and a high seat for the king. The hall is the symbol of the heroic ideal: the place where the warriors drink mead, listen to the harper, receive gifts, and take counsel.
Twelve years before Beowulf’s arrival, the hall has been under attack by the monster Grendel. The poet describes the monster as a creature descended from Cain, the first murderer, and thus as an emblem of original sin and original evil. The reading is Christian: the monsters of the pagan world are seen as descendants of the biblical murderer. The reading is also older than the Christian one: Grendel is an ogre, a giant, a creature of the wastes.
For twelve years Hrothgar’s warriors have slept in the hall in dread. Every night Grendel comes, seizes a sleeping warrior, tears him apart, drinks his blood, and devours him. The hall is half empty.
The Coming of Beowulf
The young Beowulf, prince of the Geats, has heard of the trouble. He and a band of fourteen chosen Geats sail to Denmark to offer the service of the Geats to Hrothgar. The journey is described in some of the poem’s most beautiful lines: the swan-road, the gleam of the sea, the lookout scanning the cliffs for the familiar shapes of land. Beowulf’s coming is a sign of hope in a long darkness. Hrothgar’s people receive him, the warriors of the hall embrace him, and at the mead-feast Beowulf and Hrothgar sit together as old allies — for Hrothgar had once paid the blood-price for Beowulf’s father, Ecgtheow.
The first half of the poem, before the fight, is a long, careful set-up. Beowulf tells the story of his young deeds, including the swimming contest with Breca and the slaying of sea-monsters with his bare hands. The warriors at the hall, including the king’s trusted advisor Unferth, challenge Beowulf on the swimming story; Beowulf answers with a long account of the sea-monsters he killed. The hall is filled with boasts and counter-boasts, the formal exchange of speech that was the norm of the heroic society.
The Refusal of Weapons
On the night of the fight, Beowulf makes a famous decision: he will not use weapons. He and his men will sleep in Heorot, fully armed (for the first time in twelve years, the hall is filled with the noise of warriors preparing for the night), and Beowulf will face Grendel unarmed. The poet presents the decision as the mark of the heroic ideal: the hero will not gain by trickery, will not meet the monster’s lack of weapons with the advantage of armor and sword. The image of the young king who will not use weapons in the fight is the image of the hero’s full self-confidence, and of the body as the supreme weapon — one of the great themes of the heroic tradition.
The Coming of Grendel
The night comes. Beowulf and his men sleep in the hall. The Geats are in the high seats, the Danes leave the hall (as they have done every night for twelve years), and the hall is dark. The poet describes the wait: the silence, the night, the moon, the wind in the trees. Then the poet hears the creak of the door — Grendel is coming.
The poet’s description of the monster is one of the most famous in Old English. Grendel is described as a creature of the dark, an enemy of God, a being of mist and shadow, with eyes like fire. He has the appearance of a man, but is greater than any man; he has the strength of thirty men. We never see Grendel’s face in the poem; we only see his grip.
Grendel comes through the dark of the hall, his eyes burning. He seizes one of Beowulf’s men — the first of the Geats — and devours him, body and armor, with one snap.
The Grip
Then Grendel reaches for Beowulf. The hero lies on the bed in the high seat, pretending to sleep. The monster’s hand closes on his arm — and finds a grip of iron.
The two grappled. The poet says that the monster was surprised; he had never felt a grip like this. Beowulf’s body, hardened in the sea-swim, in the fights with the sea-monsters, in the long training of the heroic life, had no equal in the world. The benches crashed, the hall trembled, the hall rang with the noise of the struggle. Beowulf’s men try to help, but they cannot find the hero in the darkness.
Then Beowulf, in the grip of his body and in the strength of his arms, tore off Grendel’s arm at the shoulder. The arm came away, bone and muscle and tendon, with a noise like the breaking of a tree. The monster, screaming, fled into the night, leaving his arm behind. The hero, exhausted but triumphant, hung the arm from the roof of Heorot as a trophy.
The Flight of Grendel
The flight of Grendel is described in some of the poem’s most beautiful lines. The monster fled across the moors, through the dark of the night, back to his den at the bottom of the mere. His blood dripped on the ground as he went, and the poet says that he knew, in his flight, that he was dying. He reached the mere and died in his cave, with the great wound in his shoulder, his body bleeding out into the waters of the lake.
The Trophy Arm
The arm of Grendel, hung from the roof of Heorot, is the central image of the fight. The arm is described in detail by the poet: the claws, the rough skin, the immense size — the whole arm of a man could fit into the span of its hand. The arm is a sign that the heroic ideal is not just a matter of words; it is a matter of the body and of the strength of the body.
The hero is celebrated in the morning. The mead-hall is filled with the noise of joy, the warriors of the Geats and the Danes sing together, the queen Wealhtheow gives Beowulf golden treasures, and the king Hrothgar embraces Beowulf as a son.
Comparison with Other Monster-Fights
The fight of Beowulf with Grendel is one of a class of monster-fights in world mythology. The closest comparisons are with Perseus and Medusa in the Greek tradition, who slays the Gorgon by using a polished shield; Theseus and the Minotaur in the Greek tradition, who descends into the labyrinth; Cú Chulainn and Fer Diad in the Irish tradition; and the Norse Thor and the giants of the Edda. The fight has also been read as a Christian allegory: Grendel is the devil, the hall is the church, the hero is Christ or the Christian warrior. The reading is partly supported by the poem, but the fight is also a fight between the heroic society and the wild.
The Continuing Influence
The image of Beowulf fighting Grendel in the great hall has been one of the most powerful in English literature. The fight is the model for many later fights in English fiction:
- The fight of Bilbo Baggins with the trolls in The Hobbit (Tolkien, 1937), which draws on the same heroic-comic tradition.
- The fights of the Arthurian knights with the giants and dragons of the Grail romances.
- The fights of the Forgotten Realms heroes with monsters in the modern fantasy role-playing game.
