Brynhildur in Norse mythology, was a captive maiden, the daughter of Budlis. She was liberated by the mighty Sigurd, when asleep. Sigurd found the maiden extraordinarily beautiful, and fell in love with her. But in Gjuki's house, at which he staved, he became inclined to forget her on drinking a magic driilk, and married Gudrun, the daughter of Grimhild. Gunnar, the brother of Gudrun, desired to possess Byrnhildur, but did not dare to fulfil a certain condition which she asked of him. He therefore persuaded the mighty Sigurd to fulfil the condition, disguised as Gunnar. Brynhildur did not discover the deceit until, when bathing with Gudrun, she discovered that the latter had the ring which she supposed she had given to Gunnar, but which she gave to Sigurd, who gave it to his wife Gudrun. Her love now turned into hate, and she sought revenge for the deceit. She instigated Glnniar and Hogni to murder Sigurd, and after killing herself she and Sigurd were burned on one funeral pile.
