Brynhildr was a valkyrie, one of the maidens of Odin who chose the slain — but she had angered the chief of the gods by giving victory in a battle to the warrior whom Odin had marked for death. As her punishment Odin condemned her to sleep within a circle of fire upon a mountain, until a hero brave enough to ride through the flames should awaken her; and on awakening, she would no longer be a valkyrie but a mortal woman, who must marry a mortal man.
Sigurd Fáfnisbani came at last and rode through the fire upon his horse Grani; Brynhildr awoke, and the two pledged themselves to each other in the depths of love. But Sigurd was bound by other fates. He came afterward to the court of the Burgundian king Gjuki, where Queen Grímhild gave him a potion of forgetfulness, so that he forgot Brynhildr; he married Gjuki's daughter Gudrun, and at Gjuki's bidding rode again through the fire — this time in the borrowed shape of his brother-in-law Gunnar — to win Brynhildr for Gunnar's wife. Brynhildr, supposing that Gunnar had ridden through the fire, agreed to marry him.
It was Gudrun who, in a quarrel at the river where the women were washing their hair, finally revealed to Brynhildr the deception. Brynhildr, knowing now that Sigurd had broken the deepest of pledges (under whatever compulsion), demanded his death; Gunnar yielded, and his younger brother Guttorm was prevailed upon to do the killing. When Sigurd was slain, Brynhildr laughed once and then fell into terrible silence; she stabbed herself with a sword, asked to be burnt with Sigurd on a single pyre, and was so. The two passed together to the underworld, joined at last in death after their separation in life.
