Gudrun wife of the great hero Sigurd. After Sigurd's death, she became the wife of Atli, king of the Huns, and later, of Jonakr of Denmark. Gudrun was the sister of King Gunnar and the warrior Hogni, and daughter of King Giuki and the sorceress Queen Grimhild. She killed king Atli in revenge for the death of her brothers. By Sigurd she had two children, Sigmund and the lovely Swanhild, by Atli she had two sons, and by Jonakr she had three sons, Sorli, Hamdir, and Erp.
In the Scandinavian 'Volsunga Saga', and the Icelandic 'Poetic (or Younger) Edda' and 'Prose (or Elder) Edda', Gudrun is a crucial character in the tales of the Volsungs and Nibelungs. The hero Sigurd came to King Giuki's court after braving the wall of flames surrounding the warrior-maiden Brunhild, with whom he fell in love. Queen Grimhild gave Sigurd a love potion that made him forget Brunhild and fall in love with the beautiful Gudrun. When Gudrun's brother King Gunnar set out to win Brunhild as his wife, Sigurd became instrumental in Gunnar's success.
In the course of an argument between Gudrun and Brunhild, Brunhild realized she had been wedded to Gunnar by deception, and in her rage sought Sigurd's death. In some versions, Gudrun's brother Hogni, jealous of Sigurd, committed the crime; in others, Hogni and Gunnar convinced their stepbrother Guttorm to stab Sigurd. Sigmund, the young son of Gudrun and Sigurd, was also killed.
Gudrun was devastated by the death of her husband and did not want to marry again. Her mother Grimhild gave her a potion of forgetfulness so that she would marry King Atli, Brynhild's brother. When the potion wore off, Gudrun came to despise Atli. Because Gudrun was heir to Sigurd's treasure, Atli hoped to wrest it from her brothers, Gunnar and Hogni, who had hidden it in the Rhine. When the brothers refused to reveal the location of the Nibelung's treasure, Atli had Hogni's heart cut out and Gunnar thrown into a snake pit.
Gudrun, who by that time had two sons with Atli, ordered the boys killed and made silver and gold goblets out of their skulls. At the funeral feast for Gunnar and Hogni, Gudrun ordered mead mixed with the boys' blood to be served to King Atli in these goblets. Their hearts were served to the king to eat. The mead was so strong that all the guests fell asleep, and as the king slept that night, Gudrun and Hogni's son killed Atli with Sigurd's sword. All the guests died in a fire Gudrun and her nephew had set in the hall.
In one version, Gudrun immolated herself in the flames, but in the 'Volsunga Saga' and the Eddas, Gudrun leapt into the sea, bent on suicide. She drifted across the fjord and washed up on the shore of the kingdom of Jonakr, who took her in and married her. Her daughter by Sigurd, Swanhild, called the most beautiful of women, had been brought up in Jonakr's court. By Jonakr Gudrun had three sons: Sorli, Hamdir, and Erp. When Swanhild was killed by her betrothed, King Jormunrek, Gudrun sent Jonakr's sons to avenge the deed, but they themselves were killed in the process. The tragic lineage of King Giuki ended with the death of Gudrun's sons. Gudrun, last of her kin, cast herself into the flames of a funeral pyre.
