While Skaldskaparmal makes Loke and no one else accompany Thor to Geirrod, and represents the whole matter as a visit to the giant by Thor, we learn from Thorsdrapa that this journey to Jotunheim is an expedition of war, which Thor makes at the head of his warriors against the much-dreaded chief of giants, and that on the way thither he had to fight a real battle with Geirrod's giants before he is able to penetrate to the destination of his expedition, Geirrod's hall, where the giants put to flight in the battle just mentioned gather, and where another battle is fought. Thorsdrapa does not mention with a single word that Loke accompanied Thor on this warlike expedition. Instead of this, we learn that he had a secret understanding with one of Geirrod's daughters, that he encouraged Thor to go, and gave him untruthful accounts of the character of the road, so that, if not Thor himself, then at least the allies who went with him, might perish by the ambush laid in wait for them. That Loke, under such circumstances, should accompany Thor is highly incredible, since his misrepresentations in regard to the character of the way would be discovered on the journey, and reveal him as a traitor. But since Skaldskaparmal states that Loke was Thor's companion, the interpreters of Thorsdrapa have allowed him so to remain, and have attributed to him--the traitor and secret ally of the giants--and to Thjalfe (who is not mentioned in the Skaldskaparmal account) the exploits which Thor's companions perform against the giants. That the poem, for instance, in the expression _Thjáfi med ýta sinni_, "Thjalfe with his companions," in the most distinct manner emphasises the fact that a whole host of warriors had Thor as their leader on this expedition, was passed over as one of the obscure passages in which the poem was supposed to abound, and the obscurity of which simply consists in their contradicting the story in Skaldskaparmal. Thorsdrapa does not mention with a single word that Thor, on his journey to Geirrod, stopped at the home of a giantess _Gridr_, and borrowed from her a staff, a belt of strength, and iron gloves; and I regard it as probable that this whole episode in Skaldskaparmal has no other foundation than that the staff which Thor uses as his support on wading across the rapid stream is in Thorsdrapa now called _grídarvölr_, "the safety staff," and again, _brautar lids tollr_, "the way-helping tree." The name _grídarvölr_, and such proverbs as _at ósi skall á stemma_ and _reynir er björg thórs_, appear to be the staple wares by the aid of which the story in Skaldskaparmal was framed. The explanation given in Skaldskaparmal of the proverb _reynir er björg thórs_, that, by seizing hold of a rowan growing on the river bank, Thor succeeded in getting out of the river, is, no doubt, an invention by the author of the story. The statement cannot possibly have had any support in the mythology. In it Thor is endowed with ability to grow equal to any stream he may have to cross. The rowan mentioned in the proverb is probably none other than the "way-helping tree," the "safety staff," on which he supports himself while wading, and which, according to Thorsdrapa (19), is a _brotningr skógar_, a tree broken or pulled up in the woods.
