There’s an interesting epilogue to my previous post: Aineías shows up in Norse mythology as a cognate of Víðarr.
And Víðarr, of course, battles the wolf Fenrir (the slayer of his father Óðinn) either with his sword, as in Völuspá stanzas 54 and 55:
Then comes Sigfather’s | mighty son,
Víðarr, to fight | with the foaming wolf;
In the giant’s son | does he thrust his sword
Full to the heart: | his father is avenged.
Or with his bare hands, as in Vafthrúdnismál stanza 53:
The wolf shall fell | the father of men,
And this shall Víðarr avenge;
The terrible jaws | shall he tear apart,
And so the wolf shall he slay.
Though they differ in their relationship with the wolf, like Aineías who led his fellow Trojans to Italy where they founded Rome, Víðarr will guide the Gods who survive Ragnarök in constructing Iðavöllr on the site where Ásgarðr once stood.
