PROOFS THAT IVALDE'S SONS ARE IDENTICAL WITH OLVALDE'S.
Observations made in the course of my investigations anent Ivalde and his sons have time and again led me to the unexpected result that Ivalde's sons, Slagfin, Egil, and Volund, are identical with Olvalde-Alvalde's sons, who, in the Grotte-song, are called _Idi_, _Urnir_ or _Aurnir_ (_Ornir_), and _thjazi_, and in the Younger Edda (p. 214) _thjazi_, _Idi_, and _Gángr_. This result was unexpected and, as it seemed to me in the beginning, improbable, for the reason that where Thjasse is mentioned in the Elder Edda, he is usually styled a giant, while Volund is called a prince or chief of elves in Volundarkvida. In Grimnersmal (11) Thjasse is designated as _inn amátki iotunn_; in Harbardsljod (19) as _enn thrudmothgi iotunn_; in Hyndluljod (30) as a kinsman of Gymer and Aurboda. The Grotte-song (9) says that Thjasse, Ide, and Aurnir were brothers of those mountain giants who were the fathers of Menja and Fenja. In the Younger Edda he is also called a _jötunn_. In the beginning of my researches, and before Volund's position in the mythology was clear to me, it appeared to me highly improbable that a prince among the elves and one of the chief artists in the mythology could be characterised as a giant. Indeed I was already then aware that the clan-names occurring in the mythology--_áss_, _vanr_, _álfr_, _dvergr_, and _jötunn_--did not exclusively designate the descent of the beings, but could also be applied to them on account of qualities developed or positions acquired, regardless of the clan to which they actually belonged by their birth. In Thrymskvida (15), so to speak in the same breath, Heimdal is called both _áss_ and _vanr_--"_thá quath that Heimdallr, hvitastr ása, vissi han vel fram sem vanir áthrir_." And Loke is designated both as _áss_ and _jötunn_, although the Asas and giants represent the two extremes. Neither Heimdal nor Loke are of the Asa-clan by birth; but they are adopted in Asgard, that is, they are adopted Asas, and this explains the appellation. Elves and dwarfs are doubtless by descent different classes of beings, but the word dwarf, which in the earliest Christian times became the synonym of a being of diminutive stature, also meant an artist, a smith, whence both Vans and elves, nay, even Fjalar, could be incorporated in the Völuspa dwarf-list. When, during the progress of my investigations, it appeared that Volund and his brothers in the epic of the mythology were the most dangerous foes of the gods and led the powers of frost in their efforts to destroy the world, it could no longer surprise me that Volund, though an elf prince, was characterised as _inn ámátki iotunn, enn thrudmothgi iotunn_. But there was another difficulty in the way: according to Hyndluljod and the Grotte-song, Thjasse and his brothers were kinsmen of giants, and must therefore undoubtedly have had giant-blood in their veins. But there are kinsmen of the giants among the Asas too; and when in the progress of the investigation it appears that Thjasse's mother is a giantess, but his father a _hapt_, a god of lower rank, then his maternal descent, and his position as an ally and chief of the giants, and as the most powerful foe of Asgard and Midgard, are sufficient to explain the apparent contradiction that he is at the same time a giant and a kinsman of the giants, and still identical with the elf-prince, Volund. It should also be observed that, as shall be shown below, the tradition has preserved the memory of the fact that Volund too was called a giant and had kinsmen among the giants.
