Grimhild now counselled her son Gunnar to woo Brynhild, and consulted with Sigurd, in consequence of this design.  Brynhild had vowed to wed that man only who should ride over the blazing fire that was laid around her hall.  They found the hall and the fire burning around it.  Gunnar rode Goti, and Hogni Holknir.  Gunnar turns his horse towards the fire, but it shrinks back.  Sigurd said:  “Why dost thou shrink back, Gunnar?” Gunnar answers:  “My horse will not leap this fire,” and prays Sigurd to lend him Grani.  “He is at thy service,” said Sigurd.  Gunnar now rides again towards the fire, but Grani will not go over.  They then changed forms.  Sigurd rides, having in his hand the sword Gram, and golden spurs on his heels.  Grani runs forward to the fire when he feels the spur.  There was now a great noise, as it is said: 

1.  The fire began to rage, and the earth to tremble, high rose the flame to heaven itself:  there ventured few chiefs of people through that fire to ride, or to leap over.

2.  Sigurd Grani with his word urged, the fire was quenched before the prince, the flame allayed before the glory-seeker with the bright saddle that Rok had owned.

Brynhild was sitting in a chair as Sigurd entered.  She asks who he is, and he calls himself Gunnar Giuki’s son.  “And thou art destined to be my wife with thy father’s consent.  I have ridden through the flickering flame (vafrlogi) at thy requisition.”  She said:  “I know not well how I shall answer this.”  Sigurd stood erect on the floor resting on the hilt of his sword.  She rose embarrassed from her seat, like a swan on the waves, having a sword in her hand, a helmet on her head, and wearing a corslet.  “Gunnar,” said she, “speak not so to me, unless thou art the foremost of men; and then thou must slay him who has sought me, if thou hast so much trust in thyself.”  Sigurd said:  “Remember now thy promise, that thou wouldst go with that man who should ride through the flickering flame.”  She acknowledged the truth of his words, stood up, and gave him a glad welcome.  He tarried there three nights, and they prepared one bed.  He took the sword Gram and laid it between them.  She inquired why he did so.  He said that it was enjoined him so to act towards his bride on their marriage, or he would receive his death.  He then took from her the ring called Andvaranaut, and gave her another that had belonged to Fafnir.  After this he rode away through the same fire to his companions, when Gunnar and he again changed forms, and they then rode home.

Brynhild related this in confidence to her foster-father Heimir, and said:  “A king named Gunnar has ridden through the flickering flame, and is come to speak with me; but I told him that Sigurd alone might so do, to whom I gave my vow at Hindarfiall, and that he only was the man.”  Heimir said that what had happened must remain as it was.  Brynhild said:  “Our daughter Aslaug thou shalt rear up here with thee.”  Brynhild then went to her father, King Budli, and he with his daughter Brynhild went to King Giuki’s palace.  A great feasting was afterwards held, when Sigurd remembered all his oaths to Brynhild, and yet kept silence.  Brynhild and Gunnar sat at the drinking and drank wine.
