This treasure, with its accompanying curse, next passes into the hands of a human being named Sigurd (the Norse form of Siegfried, as we have seen), a descendant of the race of the Volsungs, who trace their history back to Wodan and are especially favored by him. The full story of Siegfried's ancestry is far too long to relate here, and does not especially concern us, as it has little or no influence on the later development of the story. It is sufficient for our purpose to know that Siegfried was the son of Siegmund, who was slain in battle before the birth of his son. Sigurd was carefully reared by his mother "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.
