Um, hey Pez, I didn’t write the source material that was on that web page, and I don’t vouch for it’s unassailable accuracy. But cfog had heard of Loki being called Sky-traveller, and, as we’ve seen, the web page I ran across noted essentially the same thing, independently. I hadn’t really considered that they might both independently have invented something completely wrong…
So I ran a quarter-of-a-second Google search, and lo and behold, immediately bazillions of references to Loki Sky-walker, Skywalker, Sky-traveller, etc come up. Like this one, at http://elfwood.lysator.liu.se/loth/u/l/uli/loki.gif.html
‘I am the mother to Odin’s stallion, Sleipnir.
I am the father of Fenrir Sun-Eater, and of Hel Halfrotted and of Jormugund the World-Serpent.
I am Loki Scar-Lip, Loki Skywalker, Loki Giant’s Child, Loki Lie-Smith.
I am Loki, who is fire and wit and hate.’
Which is evidently quoting a common transcription of Norse myth, since the same quote comes up several times on several different unassociated web pages from around the world (doesn’t say which text, however). Note that it also quite clearly says “I am Loki, who is fire…” I don’t know much about Norse mythology, so I don’t know why you feel this is so clearly wrong, but perhaps the following is part of your thought train, quoted from this site:
http://www.thetroth.org/resources/ourtroth/loki.html
"Although there is no direct Norse evidence for the nineteenth-century reading of Loki as a fire-god (based on a false etymology connecting him with logi, ‘flames’)…
Loki has several heiti, including Hveðrungr (roarer? - Völuspá 55, Ynglingatal 32), Loptr (he who fares aloft - or, as Paul translates it, “Skywalker”), and perhaps Lóðurr (etymology difficult)."
So, as I say, I have no particular expertise on or familiarity with details of Norse myth, but there do seem to be a few different interpretations of Loki out there, many of which refer to him as Sky-Walker, and others which claim him as the god of fire. I’m not as sure they’re all wrong as you’ve indicated, but I recommend you look around for yourself and see what’s out there.
And remember, oral traditions are, by definition, almost impossible to trace back to their origins (most don’t HAVE exact origins). Scholars are bound to make huge mistakes in their assumptions, and to teach these mistakes to thousands of students. I wouldn’t go parsing folklore, especially folklore with very little written textual record, for definitive absolutes.
