The Story of Sigurd the Volsung — William Morris

Son of King Sigmund, young Sigurd is taught the ways of kings by the ancient, mysterious Regin - who then sets him upon the seemingly impossible task: to steal the divine armor guarded by the Wallower on the Gold - the great serpent Fafnir. Astride the war-steed Grayfell and armed with a sword named the Wrath of Sigurd, the young hero crosses the Glittering Heath in pursuit of peril, glory - and the Treasure of Andvari.
