Meanwhile Grimhild urges her son Gunnar to sue for the hand of Brynhild. Taking with him Sigurd and a few others, Gunnar visits first Brynhild's father "Budli", and then her brother-in-law "Heimir", from both of whom he learns that she is free to choose whom she will, but that she will marry no one who has not ridden through the wall of flame. With this answer they proceed to Brynhild's castle, where Gunnar is unable to pierce the flames, even when seated on Sigurd's steed. Finally Sigurd and Gunnar change forms, and Sigurd, disguised as Gunnar, rides through the wall of fire, announces himself to Brynhild as Gunnar, the son of Giuki, and reminds her of her promise to marry the one who penetrated the fire. Brynhild consents with great reluctance, for she is busy carrying on a war with a neighboring king. Sigurd then passes three nights at her side, placing, however, his sword Gram between them, as a bar of separation. At parting he draws from her finger the ring, with which he had originally pledged his troth to her, and replaces it with another, taken from Fafnir's hoard. Soon after this the marriage of Gunnar and Brynhild is celebrated with great splendor, and all return to Giuki's court, where they live happily for some time. One day, however, when the ladies go down to the river to take a bath, Brynhild will not bathe further down stream than Gudrun, that is, in the water which flows from Gudrun to her, (5) giving as the reason, that her father was mightier and her husband braver, since he had ridden through the fire, while Sigurd had been a menial. Stung at this, Gudrun retorts that not Gunnar but Sigurd had penetrated the flames and had taken from her the fateful ring "Andvaranaut", which she then shows to her rival in proof of her assertion. Brynhild turns deathly pale, but answers not a word. After a second conversation on the subject had increased the hatred of the queens, Brynhild plans vengeance. Pretending to be ill, she takes to her bed, and when Gunnar inquires what ails her, she asks him if he remembers the circumstances of the wooing and that not he but Sigurd had penetrated the flames. She attempts to take Gunnar's life, as she had pledged her troth to Sigurd, and is thereupon placed in chains by Hogni. Seven days she sleeps, and no one dares to wake her. Finally Sigurd succeeds in making her talk, and she tells him how cruelly she has been deceived, that the better man had been destined for her, but that she had received the poorer one. This Sigurd denies, for Giuki's son had killed the king of the Danes and also Budli's brother, a great warrior. Moreover, although he, Sigurd, had ridden through the flames, he had not become her husband. He begs her therefore not to harbor a grudge against Gunnar.
