Sæmund’s Edda (Thorpe’s tr.).
On arriving at Hreidmar’s house, Loki found the mighty treasure none too great, for the skin became larger with every object placed upon it, and he was forced to throw in the ring Andvaranaut (Andvari’s loom), which he had intended to retain, in order to secure the release of himself and his companions. Andvari’s curse of the gold soon began to operate. Fafnir and Regin both coveted a share, while Hriedmar gloated over his treasure night and day, and would not part with an item of it. Fafnir the invincible, seeing at last that he could not otherwise gratify his lust, slew his father, and seized the whole of the treasure, then, when Regin came to claim a share he drove him scornfully away and bade him earn his own living.
Thus exiled, Regin took refuge among men, to whom he taught the arts of sowing and reaping. He showed them how to work metals, sail the seas, tame horses, yoke beasts of burden, build houses, spin, weave, and sew—in short, all the industries of civilised life, which had hitherto been unknown. Years elapsed, and Regin patiently bided his time, hoping that some day he would find a hero strong enough to avenge his wrongs upon Fafnir, whom years of gloating over his treasure had changed into a horrible dragon, the terror of Gnîtaheid (Glittering Heath), where he had taken up his abode.
His story finished, Regin turned suddenly to the attentive Sigurd, saying he knew that the young man could slay the dragon if he wished, and inquiring whether he were ready to aid him to avenge his wrongs.
“And he spake: ‘Hast thou hearkened, Sigurd? Wilt thou help a man that is old
To avenge him for his father? Wilt thou win that treasure of Gold
And be more than the Kings of the earth? Wilt thou rid the earth of a wrong
And heal the woe and the sorrow my heart hath endured o’er long?’”
Sigurd’s Sword
Sigurd immediately assented, on the condition, however, that the curse should be assumed by Regin, who, also, in order to fitly equip the young man for the coming fight, should forge him a sword, which no blow could break. Twice Regin fashioned a marvellous weapon, but twice Sigurd broke it to pieces on the anvil. Then Sigurd bethought him of the broken fragments of Sigmund’s weapon which were treasured by his mother, and going to Hiordis he begged these from her; and either he or Regin forged from them a blade so strong that it divided the great anvil in two without being dinted, and whose temper was such that it neatly severed some wool floating gently upon the stream.
