Naught did he care for peril who had come to seek such prize, and, as if daunted by the courage of the Volsung, the fierce flames shrank back as he advanced, leaving ever a magic circle in which he rode unscathed, while all around they roared like some hungry lion robbed of its prey. They rose wave upon wave to the very sky, but their fierce glare shone with glory upon Sigurd, and his form was as that of the Sun-god when he rises from the ever-lasting hills at the dawn of day. And suddenly, as though their work was done, the flames flickered and fell, leaving only a broad ring of pale ashes behind the hero as he rode on to where loomed the massive shape of a great castle hung with shields. The doors of this castle stood wide open, and not a warrior was to be seen; so, dismounting, Sigurd entered the great hall, and at first saw no one--neither man, woman, nor child. But presently he came to a room where he saw a figure, clad all in armour, lying stretched upon a couch. Approaching thither, Sigurd removed the helmet, and saw, to his astonishment, the face of a beautiful maiden fast asleep. He called to her and tried to awaken her, but in vain. Then he cut off the breastplate, which was fastened so closely that it seemed as though it had grown into her flesh, and then the sleeves and the long steel boots; and at length she lay before him in her garments of fine white linen, over which fell long, thick tresses of golden hair. Sigurd bent over her in admiration, and at that moment she opened her beautiful eyes and gazed in wonder at his face. Then she arose, and looked with joy at the rising sun, but her gaze returned to Sigurd; and the two loved each other at first sight. When they had communed tenderly together, Sigurd told who he was and whence he came; and Brunhild rejoiced to hear the tale. "For," said she, "none but a hero might pass through that ring of fire." Then said Sigurd: "Tell me now, fair Brunhild, how thou camest to this lonely fire-girt castle." And she told him this tale: "A warrior-maiden am I--chief of those Valkyrs who carry off the valiant dead to the halls of Valhalla and ply them with mead at the banquet. But many years ago I gave dire offence to All-Father Odin, as thou shalt hear. "Two kings had a quarrel, and determined to put their feud to the issue of the sword. One was named Helm Gunnar. He was an old man and a mighty warrior, and to him had Odin promised the victory. "But for the other, young Agnar, my heart was filled with pity; and so I disregarded the command of Odin and struck down Helm Gunnar in the fight, the victory thus going to Agnar.
