Beowulf is an Old English epic poem, given here in Gummere's Modern English verse. It opens not with its hero but with the Danish royal line, tracing the founder Scyld Scefing and his descendants down to King Hrothgar, who builds the great mead-hall Heorot as a seat of feasting and gift-giving.
Heorot's joy draws a monster. Grendel, a creature of the moors descended from Cain, raids the hall by night and devours Hrothgar's men for twelve years, leaving the Danes helpless. Word of this reaches the land of the Geats, and Beowulf, a young warrior of King Hygelac, sails across the sea with his band to offer his help.
Beowulf fights Grendel bare-handed in the hall, tears off the monster's arm, and the creature flees to die in its lair. The Danes rejoice, but the next night Grendel's mother comes for revenge and carries off a man. Beowulf follows her down into a haunted mere, kills her with a giant's sword found in her hall, and returns to Hrothgar laden with honor and reward before sailing home to his own king.
The poem then leaps across many years. Beowulf has become king of the Geats and has ruled well for fifty winters when a dragon, roused by a stolen cup from its hoard, begins to burn the land. The aged king arms himself for one last fight, knowing it may be his death. His chosen warriors flee in terror, and only the young kinsman Wiglaf stands with him.
Together they kill the dragon, but Beowulf is mortally wounded. Dying, he looks on the won treasure, gives Wiglaf his last commands, and asks for a barrow to be raised on the headland in his memory. His people burn his body, build the mound, and mourn a king they call the mildest and kindest of men. The closing lines leave the Geats fearing the feuds that his death will let loose.
