The vocation of the sons of Ivalde, as the keepers of the Hvergelmer fountain and of the Elivagar, has its counterpart in the vocation which, in the Iranian mythology, is attributed to Thjasse's prototype, the star-hero Tistrya (Tishya). The fountain Hvergelmer, the source of the ocean and of all waters, has in the Iranian mythology its counterpart in the immense body of water Vourukasha. Just as the Teutonic world-tree grows from its northern root out of Hvergelmer, the Iranian world-tree Gaokerena grows out of Vourukasha (Bundehesh, 18). Vourukasha is guarded by Tistrya, assisted by two heroes belonging to the class of mythological beings that are called Yazatas (Izads; in the Veda literature Yajata), "they who deserve offerings," and in the Iranian mythology they form the third rank of divine beings, and thus correspond to the elves of the Teutonic mythology. Assisted by these two heroes and by the "fevers of the just," Tistrya defends Vourukasha, and occasionally fights against the demon Apaosha, who desires to destroy the world (Bundehesh, 7). Tistrya, as such, appears in three forms: as a youth with bright and glistening eyes, as a wild boar, and as a horse. Can it be an accident that these forms have their counterparts in the Teutonic mythology in the fact that one of Thjasse's brothers (Egil-Orvandel-Ebur) has the epithet "wild boar," and that, as shall be shown below, his other brother (Slagfin) bears the epithet Hengest, and that Thjasse-Volund himself, who for years was possessor of, and presumably invented, the "remedy against aging," which Idun, his beloved, has charge of--that Thjasse-Volund himself was regarded as a youth with a "white neck" (Volundarkvida, 2) and with glittering eyes (Volundarkvida, 17), which after his death were placed in the heavens as stars?
SLAGFIN. HIS IDENTITY WITH GJUKE. SLAGFIN, EGIL, AND VOLUND ARE NIFLUNGS.

I now come to the third Ivalde son, Slagfin. The name Slagfin (_Slagfidr_) occurs nowhere else than in Volundarkvida, and in the prose introduction to the same. All that we learn of him is that, like Egil, he accompanied his brother Volund to the Wolfdales; that, like them, he runs on skees and is a hunter; and that, when the swan-maids, in the ninth year of their abode in the Wolfdales, are overcome by longing and return to the south, he goes away to find his beloved, just as Egil goes to find his. We learn, furthermore, that Slagfin's swan-maid is a sister of Volund's and a kinswoman of Egil's, and that she, accordingly, is Slagfin's sister (half-sister). She is called _Hladgudr Svanhvit_, likewise a name which occurs nowhere else. Her (and accordingly also that of Volund's swan-maid) mother is called Swan-feather, _Svanfjödr_ (Slagfin's beloved is _Svanfjadrar drós_--str. 2). The name Svan-feather reminds us of the Svanhild Gold-feather mentioned in Fornm., ii. 7, wife of one Finalf. If Svanfeather is identical with Svanhild Goldfeather, then Finalf must originally be identical with Ivalde, who also is an elf and bears the name _Finnakonungr_, _Sumblus Phinnorum rex_. But this then simply confirms what we already know, namely, that the Ivalde sons and two of the swan-maids are brothers and sisters. It, however, gives us no clue by which we can trace Slagfin in other sources, and rediscover him bearing other names, and restore the myth concerning him which seems to be lost. That he, however, played an important part in the mythology may be assumed already from the fact that his brothers hold places so central in the great epic of the mythology. It is, therefore, highly probable that he is mentioned in our mythic fragments, though concealed under some other name. One of these names, viz., Ide, we have already found (see No. 114); and thereby we have learned that he, with his brother Egil, had a citadel near the Elivagar, and guarded their coasts against the powers of frost. But of his fate in general we are ignorant. No extensive researches are required, however, before we find circumstances which, compared with each other, give us the result that Slagfin is Gjuke, and therewith the way is open for a nearer acquaintance with his position in the heroic saga, and before that in the mythology. His identity with Gjuke is manifest from the following circumstances:
