The names also connect those whom we find to be kinsmen of Volund with Thjasse's. Alvalde is Thjasse's father; Ivalde is Volund's. _Ívaldi_ is another form for _Idvaldi_. The long prefixed _Í_ in _Ívaldi_ is explained by the disappearance of _d_ from _Idvaldi_. _Id_ reappears in the name of Ivalde's daughter _Idunn_ and Thjasse's brother _Idi_, and these are the only mythological names in which _Id_ appears. Furthermore, it has already been pointed out, that of Alvalde's (_Ölvaldi's_) three sons there is one who has the epithet Wildboar (_Aurnir, Urnir_); and that among Ivalde's three sons there is one--namely, Orvandel-Egil--who has the same epithet (_Ibor, Ebur, Ebbo_); and that among Alvalde's sons one--namely, Thjasse--has the epithet _Fjallgyldir_, "mountain-wolf" (Haustlaung); while among Ivalde-Olmod's sons there is one--namely, Volund--who has the epithet _Ásólfr_, which also means "mountain-wolf."
In this connection it must not be forgotten that tradition has attached the qualities of giants, not only to Thjasse, but also to Volund. That this does not appear in the Elder Edda depends simply on the fact that Volund is not mentioned by this name in the genuine mythic songs, but only in the heroic fragment which we have in Volundarkvida. The memory that Volund, though an elf-prince in the mythology, and certainly not a full-blooded giant on his father's side, was regarded and celebrated in song as an _iötunn_,--the memory of this not only survives in Vilkinasaga, but appears there in an exaggeration fostered by later traditions, to the effect that his father Vade (see No. 110) is there called a giant, while his father's mother is said to have been a mermaid. In another respect, too, there survives in Vilkinasaga the memory of a relationship between Volund and the most famous giant-being. He and the giants Etgeir (_Eggther_) and Vidolf are cousins, according to chapter 175. If we examine the Norse sources, we find Vidolf mentioned in Hyndluljod (53) as progenitor of all the mythological valas, and Aurboda, the most notorious of the valas of mythology, mentioned in strophe 30 as a kinswoman of Thjasse. Thus while Hyndluljod makes Thjasse, the Vilkinasaga makes Volund, a kinsman of the giant Vidolf.
