The story of Beowulf features a concept, common in early Germanic societies, known as wergild (pronounced WAIR-geld). This was the price set on a person's life based on that person's value to society. If an individual was killed, the family received wergild to compensate for the loss. In Beowulf, Hrothgar presents Beowulf with wergild for the Geatish warrior who was killed fighting Grendel. According to Germanic law, the system of wergild was meant as an alternative to seeking revenge for the loss of a loved one.
That night, the Geats stay at Heorot. Grendel soon appears and, before Beowulf can stop him, kills one of Beowulf s own men. Grendel then grabs Beowulf, but the mighty warrior seizes the monster’s arm with his powerful grip. Beowulf and Grendel struggle until Grendel finally manages to wrench himselfaway, leaving his arm in Beowulf's grasp. The monster staggers back to his cave to die. The severed arm is hung in Heorot as a trophy for all to see. Hrothgar showers Beowulf with gifts and honors him with another feast. The Danes believe they will finally be able to sleep in peace at Heorot again.
Grendel's Mother The Danes’ troubles are not over. When Grendel’s mother sees her dying son, she vows revenge. She goes to Heorot at night and surprises the Danish warriors. After killing the king's most trusted adviser, she leaves with Grendel's arm. Again the Danes call upon Beowulf for help.
Beowulf and several warriors track the monster to her lair in the swamps. They find it at the base of a cliff at the bottom of a pool bubbling with blood and gore. Unferth, who has by now changed his opinion of Beowulf, lends him Hrunting, his sword. Brandishing it, Beowulf leaps into the slimy waters. Grendel's mother grabs Beowulf and pulls him into a cave where the water cannot enter. Beowulf strikes at the monster with Hrunting, but the sword does not hurt her. The two wrestle, and Grendel's mother almost kills Beowulf, but his armor saves him. Then he sees a giant sword hanging on the wall of the cave. He grabs it and, with one mighty swing, cuts off the monster’s head. At the back of the cave, he sees Grendel’s corpse.
Using the same sword, he cuts off Grendel’s head and returns to the surface with it. He also brings the remains of the sword. Beowulf and his men return to Heorot in triumph, and Hrothgar again rewards them. Finally, the Geats go home to Sweden where Beowulf eventually becomes king.
Beowulf and the Dragon As the second part of the epic begins, Beowulf has ruled for fifty years, and his kingdom has prospered. A winged dragon lives in the land, protecting an ancient treasure buried hundreds of years earlier. One day, a slave who had been punished by his master runs away and finds the cave where the treasure is buried. To earn his master’s forgiveness, the slave steals a golden cup and takes it to his household. When the dragon inspects the treasure, as he did every day, he quickly notices the missing cup. To punish the Geats for stealing from him, the dragon flies over the countryside breathing fire on the villages and setting homes ablaze.
Though he is now an old man, Beowulf decides to fight the dragon. He and eleven warriors find the dragon’s cave, but Beowulf insists on fighting the dragon alone. Early in the battle, Beowulf discovers that his iron shield will not protect him against the dragon’s fiery breath. Just as Beowulf is about to be killed, a warrior named Wiglaf, Beowulf s young kinsman, rushes to his aid. With Wiglaf s help, Beowulf slays the dragon. Mortally wounded in the battle, the king asks Wiglaf to bring out the treasure so that he might see it before he dies.
In accordance with Norse burial customs, Beowulf's body is burned in a great fire on a cliff overlooking the sea. The treasure is placed in the fire with Beowulf as a sacrifice. A large burial mound is built over the remains of the fire to serve as a reminder of the great king, and to provide a landmark for seafarers. The poem ends with a ceremony of praise for Beowulf.
