Several Skalds mention legends of Thor: his fishing for the World-Snake is told by Bragi (who from his place in genealogies must have written before 900), and by Ulf Uggason and Eystein Valdason, both in the second half of the tenth century; and Thjodulf and Eilif (the former about 960, the latter a little later) tell tales of his fights with the giants. Turning to the other Gods, Egil Skallagrimsson (about 970) names Frey and Njörd as the givers of wealth; Bragi tells the story of Gefion's dragging the island of Zealand out of Lake Wener into the sea; and Ulf Uggason speaks of Heimdal's wrestling with Loki.
The legend of Idunn is told by Thjodulf much as Snorri tells it: Odin, Hoeni and Loki, while on a journey, kill and roast an ox. The giant Thiazi swoops down in eagle's shape and demands a share; Loki strikes the eagle, who flies off with him, releasing him only on condition that he will betray to the giants Idunn, “the care-healing maid who Page 37understands the renewal of youth.” He does so, and the Gods, who grow old and withered for want of her apples, force him to go and bring her back to Asgard.
The poet of Eiriksmal, quoted above, alludes to the Baldr myth: Bragi, hearing the approach of Eirik and his host, asks “What is that thundering and tramping, as if Baldr were coming back to Odin's hall?” The funeral pyre of Baldr is described by Ulf Uggason: he is burnt on his ship, which is launched by a giantess, in the presence of Frey, Heimdal, Odin and the Valkyries.
Though heathen writers outside of Scandinavia are lacking, references to Germanic heathendom fortunately survive in several Continental Christian historians of earlier date than any of our Scandinavian sources. The evidence of these, though scanty, is corroborative, and the allusions are in striking agreement with the Edda stories in tone and character.
Odin (Wodanus) is always identified by these writers with the Roman Mercurius (whom Tacitus named as the chief German God). This identification occurs in the eighth-century Paulus Diaconus, and in Jonas of Bobbio (first half of the seventh century), and probably rests on Odin's character as a wandering God (Mercury being διάκτορος), his disguises, and his patronage of poetry and eloquence (as Mercury is λόγιος). Odin Page 38is not himself in general the conductor of dead souls (ψυχοπομπός), like the Roman God, his attendant Valkyries performing the office for him. The equation is only comprehensible on the presumption of the independence of Germanic mythology, and cannot be explained by transmission. For if Odin were in any degree an imitation of the Roman deity, other notable attributes of the latter would have been assigned to him: whereas in the Edda the thieving God (κλέπτης) is not Odin but Loki, and the founder of civilisation is Heimdal.
The legend of the origin of the Lombards given by Paulus Diaconus illustrates the relations of Odin and Frigg. The Vandals asked Wodan (Odin) to grant them victory over the Vinili; the latter made a similar prayer to Frea (Frigg), the wife of Wodan. She advised them to make their wives tie their hair round their faces like beards, and go with them to meet Wodan in the morning. They did so, and Wodan exclaimed, “Who are these Long-beards?” Then Frea said that having given the Vinili a name, he must give them the victory (as Helgi in the Edda claims a gift from Svava when she names him). As in Grimnismal, Odin and Frigg are represented as supporting rival claims, and Frigg gains the day for her favourites by superior cunning. This legend also shows Odin as the giver of victory.
Few heathen legends are told however by these Page 39early Christian writers, and the Gods are seldom called by their German names. An exception is the Frisian Fosite mentioned by Alcuin (who died 804) and by later writers; he is to be identified with the Norse Forseti, the son of (probably at first an epithet of) Baldr, but no legend of him is told. It is disappointing that these writers should have said so little of any God except the chief one. A very characteristic touch survives in Gregory of Tours (died 594), when the Frank Chlodvig tells his Christian wife that the Christian God “cannot be proved to be of the race of the Gods,” an idea entirely in keeping with the Eddic hierarchy. Before leaving the Continental historians, reference may be made to the abundant evidence of Germanic tree-worship to be gathered from them. The holy oak mentioned by Wilibald (before 786), the sacred pear-tree of Constantius (473), with numerous others, supply parallels to the World-Ash which is so important a feature of Norse mythology.
A study of this subject would be incomplete without some reference to the mythology of Saxo Grammaticus. His testimony on the old religion is unwilling, and his effort to discredit it very evident. The bitterness of his attack on Frigg especially suggests that she was, among the Northmen, a formidable rival to the Virgin. When he repeats a legend of the Gods, he transforms them into Page 40mortal heroes, and when, as often happens, he refers to them accidentally as Gods, he invariably hastens to protest that he does so only because it had been the custom. He describes Thor and Odin as men versed in sorcery who claimed the rank of Gods; and in another passage he speaks of the latter as a king who had his seat at Upsala, and who was falsely credited with divinity throughout Europe. His description of Odin agrees with that in the Edda: an old man of great stature and mighty in battle, one-eyed, wearing a great cloak, and constantly wandering about in disguise. The story which Saxo tells of his driving into battle with Harald War-tooth, disguised as the latter's charioteer Brun, and turning the fight against him by revealing to his enemy Ring the order of battle which he had invented for Harald's advantage, is in thorough agreement with the traditional character of the God who betrayed Sigmund the Volsung and Helgi Hundingsbane. Saxo's version of the Baldr story has been mentioned already. Baldr's transformation into a hero (who could only be slain by a sword in the keeping of a wood-satyr) is almost complete. But Odin and Thor and all the Gods fight for him against his rival Hother, “so that it might be called a battle of Gods against men”; and Nanna's excuse to Baldr that “a God could not wed with a mortal,” preserves a trace of his origin. The chained Loki appears in Saxo as Page 41Utgarda-Loki, lying bound in a cavern of snakes, and worshipped as a God by the Danish king Gorm Haraldsson. Dr. Eydberg sees the Freyja myth in Saxo's story of Syritha, who was carried away by the giants and delivered by her lover Othar (the Od of the Edda): an example, like Svipdag and Menglad, of the complete transformation of a divine into an heroic myth. In almost all cases Saxo vulgarises the stories in the telling, a common result when a mythical tale is retold by a Christian writer, though it is still more conspicuous in his versions of the heroic legends.
