Volsung, a lineal descendant from Odin, built his dwelling around the trunk of a mighty oak, the Branstock, whose branches overshadowed his whole dwelling. When Signy, Volsung's only daughter, was married against her will to Siggier, king of the Goths, a one-eyed stranger (Odin) suddenly appeared among the wedding guests, and thrust a priceless sword (Balmung) deep into the bole of the homestead oak. Before departing, as abruptly as he had come, the stranger proclaimed the weapon should belong to the man who pulled it out, and prophesied that it would assure him the victory in every fight.
"Now let the man among you whose heart and hand may shift
To pluck it from the oak-wood e'en take it for my gift.
Then ne'er, but his own heart falter, its point and edge shall fail
Until the night's beginning and the ending of the tale."[35]
Although conscious that Odin had been in their midst, Volsung courteously invited the bridegroom to try his luck first, then himself attempted to draw out the divine sword, before he bade his ten sons exert their strength in turn. Only the youngest, Sigmund, was at last able to perform the required feat, and when Siggier eagerly offered to purchase his trophy from him, he firmly refused to part with it. Full of anger at this refusal, the Goth departed on the morrow, but although Signy loyally warned her kinsmen that her husband was plotting revenge, the Volsungs accepted his invitation to visit them soon.
When Volsung and his ten sons arrived in Gothland, Signy again bade them beware of coming treachery, but all in vain. The brave Volsungs, drawn into an ambush by their wily foe, were seized and bound fast to a fallen tree in a lonely forest, where every night a wild beast devoured one of these helpless men. Closely watched by her cruel husband, Signy could lend no aid to the prisoners, but when none but Sigmund, the youngest, was left, she directed a slave to smear his face with honey. The wild beast, attracted by the sweet odor, licked the face of the last prisoner, who, thus enabled to catch its tongue between his teeth, struggled with the beast until his bonds broke and he was free!
When Siggier sent to investigate as usual the next morning, his messenger reported no prisoners were left bound to the tree and that only a heap of bones was visible. Sure his foes were all dead, Siggier ceased to watch his wife, who, stealing out into the forest to bury the remains of her kin, discovered Sigmund in a thicket, and promised to aid him to obtain his revenge. To redeem this promise she sent to her brother, one after another, two of her sons to be trained as avengers, but, as both of these children proved deficient in courage, she came to the conclusion none but a pure-blooded Volsung would meet their requirements. To secure an offspring of this strain, Signy, disguised as a gypsy, secretly visited her brother's hut, and when their child, Sinfiotli, was older, sent him to Sigmund to foster and train.
With a youthful helper whom nothing could daunt, Sigmund, after achieving sundry adventures, lay in wait in Siggier's cellar, but, warned by two of his young children that murderers were hiding behind his casks, Siggier had them seized and cast into separate cells. There he decreed they should starve to death. But, before their prison was closed, Signy cast into it a bundle of straw, wherein she had concealed Balmung, the magic sword. Thanks to this weapon, Sigmund and Sinfiotli not only hewed their way out of their separate prisons, but slew all the Goths who attempted to escape from Siggier's dwelling, which they set aflame. But, although both proposed to save Signy, she merely stepped out of the house long enough to reveal Sinfiotli's origin and bade them farewell, ere she plunged back into the flames!
And then King Siggier's roof-tree upheaved for its utmost fall,
And its huge walls clashed together, and its mean and lowly things
The fire of death confounded with the tokens of the kings.
A sign for many people on the land of the Goths it lay,
A lamp of the earth none needed, for the bright sun brought the day.
Feeling he had done his duty by avenging his father's and brothers' death, Sigmund now returned home, where in his old age he was slain in battle shortly after his marriage to a young wife. Finding him dying on the battle-field, this wife bore off the fragments of his magic sword as sole inheritance for his child, whom she hoped would prove a boy who could avenge him. One version of the story relates that to escape the pursuit of Sigmund's foes this expectant mother plunged into the woods and sought help and refuge in the smithy of Mimer, a magician as well as a blacksmith. Here she gave birth to Sigurd, who, as she died when he was born, was brought up by Mimer, who marvelled to find the boy absolutely fearless.
Another version claims that, discovered by a Viking, mourning over her dead spouse, the widow was carried off by him, and consented to become his wife on condition he would prove a good foster-father to Sigmund's child. In this home Sigurd was educated by the wisest of men, Regin, who taught him all a hero need know, and directed him how to select his wonderful steed Grane or Greyfell (a descendant of Odin's Sleipnir), from a neighboring stud.
Seeing the youth ready for adventure, Regin now told him how the gods Odin, Hoenir, and Loki, wandering upon earth in the guise of men, once slew an otter, which they carried to a neighboring hut, asking to have its meat served for their dinner. Their host, however, exclaiming they had killed his eldest son who often assumed the form of an otter, seized and bound them fast, vowing they should not be free until they gave as ransom gold enough to cover the huge otter-skin.
