(l) Then he quite unexpectedly disappeared (str. 3432) from the sight of men.
(m) This happened against his will. He had suddenly been banished and delivered to the world of giants, where "waves of sorrow" long oppressed him (str. 1809, &c.).
(n) He had become changed to a dragon (wyrm, draca).
(o) The dragon dwelt near a rocky island in the sea under harne stan (beneath a grey rock).
(p) There he slew a hero of the Volsung race (in the Beowulf poem Sigemund—str. 1747, &c.).
All these points harmonise completely with Svipdag's saga, as we have found it in other sources. Svipdag is the stepson of Halfdan the Skjoldung, and has been reared in his halls, and dwells there until his mother Groa is turned out and returns to Orvandel. He sets out like Hermod on long journeys, and is doubtless the most famous traveller mentioned in the mythology; witness his journey across the Elivagar, and his visit to Jotunheim while seeking Frey and Freyja; his journey across the frosty mountains, and his descent to the lower world, where he traverses Nifelheim, sees the Eylud mill, comes into Mimer's realm, procures the sword of victory, and sees the glorious castle of the ásmegir; witness his journey over Bifrost to Asgard, and his warlike expedition to the remote East (see also Younger Edda, i. 108, where Skirner is sent to Svartalfaheim to fetch the chain Glitner). He is, like Hermod, endowed with extraordinary strength, partly on account of his own inherited character, partly on account of the songs of incantation sung over him by Groa, on account of the nourishment of wisdom obtained from his stepmother and finally on account of the possession of the indomitable sword of victory. By being adopted in Asgard as Freyja's husband, he is, like Hermod, elevated to a position of power greater than that which mortals may expect. But all this does not turn out to be a blessing to the Skjoldungs, but is a misfortune to them. The hatred he had cherished toward the Skjoldung Halfdan is transferred to the son of the latter, Hadding, and he persecutes him and all those who are faithful to Hadding, makes war against him, and is unwilling to end the long war, although the gods demand it. Then he suddenly disappears, the divine wrath having clothed him with the guise of a strange animal, and relegated him to the world of water-giants, where he is slain by Hadding (who in the Norse heroic saga becomes a Volsung, after Halfdan, under the name Helge Hundingsbane, was made a son of the Volsung Sigmund).
Hermod is killed on a rocky island under harne stan. Svipdag is killed in the water, probably in the vicinity of the Vágasker and the Singasteinn, where the Brisingamen ornament of his faithful Mardol is discovered by Loke and Heimdal.
Freyja's love and sorrow may in the mythology have caused the gods to look upon Svipdag's last sad fate and death as a propitiation of his faults. The tears which the Vana-dis wept over her lover were transformed, according to the mythology, into gold, and this gold, the gold of a woman's faithfulness, may have been regarded as a sufficient compensation for the sins of her dear one, and doubtless opened to Svipdag the same Asgard-gate which he had seen opened to him during his life. This explains that Hermod is in Asgard in the historical time, and that, according to a revelation to the Swedes in the ninth century, the ancient King Erik was unanimously elevated by the gods as a member of their council.
Finally, it should be pointed out that the Svipdag synonym Odr has the same meaning as môd in Heremôd, and as ferhd in Svidferhd, the epithet with which Hermod is designated in the Beowulf strophe 1820. Odr means "the one endowed with spirit," Heremôd "the one endowed with martial spirit," Svidferhd, "the one endowed with mighty spirit."
