They received Sigurd with much honour. Grimhild knew of his relations with Brunhild, and gave him a potion which produced forgetfulness of the war-maiden, so that he accepted the hand of Gudrun which Giuki offered him. The marriage was celebrated with great splendour, and Sigurd remained at Giuki's court, much acclaimed for his deeds of skill and valour. Grimhild meanwhile urged upon her son Gunnar to sue for the hand of Brunhild. He resolved to accept her advice and set out to visit her, taking with him Sigurd and a few other friends. He first visited Brunhild's father Budli, and afterward her brother-in-law Heimir, from whom he heard that Brunhild was free to choose the man she desired, but that she would espouse no one who had not ridden through the hedge of flame. They proceeded to Brunhild's castle. Gunnar attempted to pierce the flames, but was unable to do so even when seated on Sigurd's horse, for Grani would not stir, knowing well that it was not his master who urged him on. At last they made use of a potion that had been given them by Grimhild, and Sigurd, in the shape of Gunnar, rode through the wall of fire. He explained to the war-maiden that he was the son of Giuki and had come to claim her hand. The destiny laid upon her by Woden compelled her to consent, but she did so with much reluctance. Sigurd then passed three nights at her side, placing his sword Gram between them as a bar of separation; but at parting he drew from her finger the ring with which he had originally plighted his troth to her, and replaced it with another taken from Fafnir's hoard. Shortly afterward the wedding of Gunnar and Brunhild was celebrated with lavish splendour, and they all returned to Giuki's court.
