"Hjordis" and the wise dwarf Regin, who taught him the knowledge of runes and of many languages. (2) At the suggestion of Regin, Sigurd asks for and receives the steed "Grani" from the king, and is then urged by his tutor to help him obtain the treasure guarded by the latter's brother Fafnir. Sigurd promises, but first demands a sword. Two, that are given him by Regin, prove worthless, and he forges a new one from the pieces of his father's sword, which his mother had preserved. With this he easily splits the anvil and cuts in two a flake of wool, floating down the Rhine. He first avenges the death of his father, and then sets off with Regin to attack the dragon Fafnir. At the advice of the former Sigurd digs a ditch across the dragon's peth and pierces him from below with his sword, as the latter comes down to drink. In dying the dragon warns Sigurd against the treasure and its curse, and against Regin, who, he says, is planning Sigurd's death, intending to obtain the treasure for himself.
When Regin sees the dragon safely dead, he creeps from his place of concealment, drinks of the blood, and, cutting out the heart, begs Sigurd to roast it for him. While doing so, Sigurd burns his fingers, and, putting them in his mouth, understands at once the language of the birds and hears them say that Sigurd himself should eat the heart and then he would be wiser than all other men. They also betray Regin's evil designs, and counsel the lad to kill his tutor. This Sigurd then does, cutting off Regin's head, drinking the blood of both brothers, and eating Fafnir's heart. (3) On the further advice of the birds Sigurd first fetches the treasure from the cave, and then journeys to the mountain "Hindarfjall", where he rescues the sleeping Valkyrie, "Sigrdrifu" ("Brynhild", "Brunhild"), who, stung by the sleep thorn of Wodan, and clad in full armor, lies asleep within a castle that is surrounded by a wall of flame. With the help of his steed Grani, Sigurd succeeds in penetrating through the fire to the castle. The sleeping maiden awakes when he cuts the armor from her with his sword, for it was as tight as if grown fast to the flesh. She hails her deliverer with great joy, for she had vowed never to marry a man who knew fear. At Sigurd's request she teaches him many wise precepts, and finally pledges her troth to him. He then departs, after promising to be faithful to her and to remember her teachings.
On his journeyings Sigurd soon arrives at the court of "Giuki" (the Norse form of the German "Gibicho", "Gibich"), a king whose court lay on the lower Rhine. Giuki has three sons, "Gunnar", "Hogni", and "Guthorm", and a daughter "Gudrun", endowed with great beauty. The queen bears the name of Grimhild, and is versed in magic, but possessed of an evil heart. (4) Sigurd is received with great honor, for his coming had been announced to Gudrun in dreams, which had in part been interpreted to her by Brynhild. The mother, knowing of Sigurd's relations to the latter, gives him a potion which produces forgetfulness, so that he no longer remembers his betrothed, and accepts the hand of Gudrun, which the king offers him at the queen's request. The marriage is celebrated with great pomp, and Sigurd remains permanently attached to Giuki's court, performing with the others many deeds of valor.
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.
Brynhild remains unconvinced, and plans Sigurd's death, and threatens Gunnar with the loss of dominion and life, if he will not kill Sigurd. After some hesitation, Gunnar consents, and, calling Hogni, informs him that he must kill Sigurd, in order to obtain the treasure of the Rhinegold. Hogni warns him against breaking his oath to Sigurd, when it occurs to Gunnar, that his brother Gutthorm had sworn no oath and might do the deed. Both now proceed to excite the latter's greed, and give him wolf's and snake meat to eat to make him savage. Twice Gutthorm makes the attempt, as Sigurd lies in bed, but is deterred by the latter's penetrating glance. The third time he finds Sigurd asleep, and pierces him with his sword. Sigurd, awakening at the pain, hurls his own sword after his murderer, fairly cutting him in two. He then dies, protesting his innocence and designating Brynhild as the instigator of his murder. Brynhild at first laughs aloud at Gudrun's frantic grief, but later her joy turns into sorrow, and she determines to share Sigurd's death. In vain they try to dissuade her; donning her gold corselet, she pierces herself with a sword and begs to be burned on Sigurd's funeral pyre. In dying she prophesies the future, telling of Gudrun's marriage to "Atli" and of the death of the many men which will be caused thereby.
After Brynhild's death Gudrun in her sorrow flees to the court of King "Half" of Denmark, where she remains seven years. Finally Grimhild learns of the place of her daughter's concealment, and tries to bring about a reconciliation with Gunnar and Hogni. They offer her much treasure, if she will marry Atli. At first she refuses and thinks only of revenge, but finally she consents and the marriage is celebrated in Atli's land. After a time Atli, who is envious of Gunnar's riches, for the latter had taken possession of Sigurd's hoard, invites him to his court. A man named "Vingi", who was sent with the invitation, changes the runes of warning, which Gudrun had given him, so that they, too, read as an invitation. The brothers determine to accept the invitation, and, though warned by many dreams, they set out for Atli's court, which they reach in due time. Vingi now breaks forth into exultations, that he has lured them into a snare, and is slain by Hogni with a battle axe.
As they ride to the king's hall, Atli and his sons arm themselves for battle, and demand Sigurd's treasure, which belongs by right to Gudrun. Gunnar refuses to surrender it, and the fight begins, after some exchange of taunting words. Gudrun tries at first to reconcile the combatants, but, failing, arms herself and fights on the side of her brothers. The battle rages furiously with great loss on both sides, until nearly all of the Nibelungs are killed, when Gunnar and Hogni are forced to yield to the power of numbers and are captured and bound. Gunnar is asked, if he will purchase his life with the treasure. He replies that he first wishes to see Hogni's bleeding heart. At first the heart of a slave is cut out and brought to him, but Gunnar recognizes it at once as that of a coward. Then they cut out Hogni's heart, who laughs at the pain. This Gunnar sees is the right one, and is jubilant, for now Atli shall never obtain the treasure, as Gunnar alone knows where it is hid. In a rage Atli orders Gunnar to be thrown to the snakes. Though his hands are bound, Gunnar plays so sweetly with his toes on the harp, which Gudrun has sent him, that all the snakes are lulled to sleep, with the exception of an adder, which stings him to the
