Svipdag is the son of the slain Swedish king's daughter.
Erik is the son of the slain Swedish king's daughter.
Saxo's account of King Frode is for the greater part the myth about Frey told as history. We might then expect to find that Svipdag, who becomes Frey's brother-in-law, should appear in some rôle in Frode's history. The question, then, is whether any brother-in-law of Frode plays a part therein. This is actually the case. Frode's brother-in-law is a young hero who is his general and factotum, and is called Ericus, with the surname Disertus, the eloquent. The Ericus who appears as Halfdan's enemy accordingly resembles Svipdag, Halfdan's enemy, in the fact that he is a son of the daughter of the Swedish king slain by Halfdan. The Ericus who is Frode-Frey's general, again, resembles Svipdag in the fact that he marries Frode-Frey's sister. This is another indication that Erik and Svipdag were identical in Saxo's mythic sources.
Let us now pursue these indications and see whether they are confirmed by the stories which Saxo tells of Halfdan's enemy Erik and Frode-Frey's brother-in-law, Erik the eloquent.
Saxo first brings us to the paternal home of Erik the eloquent. In the beginning of the narrative Erik's mother is already dead and his father is married a second time (Hist., 192). Compare with this the beginning of Svipdag's history, where his mother, according to Grogalder, is dead, and his father is married again.
The stepmother has a son, by name Rollerus, whose position in the myth I shall consider hereafter. Erik and Roller leave their paternal home to find Frode-Frey and his sister Gunvara, a maiden of the most extraordinary beauty. Before they proceed on this adventurous journey Erik's stepmother, Roller's mother, has given them a wisdom-inspiring food to eat, in which one of the constituent parts was the fat of three serpents. Of this food the cunning Erik knew how to secure the better part, really intended for Roller. But the half-brothers were faithful friends.
From Saxo's narrative it appears that Erik had no desire at all to make this journey. It was Roller who first made the promise to go in search for Frode and his sister, and it was doubtless Erik's stepmother who brought about that Erik should assist his brother in the accomplishment of the task. Erik himself regarded the resolve taken by Roller as surpassing his strength (Hist., 193).
This corresponds with what Grogalder tells us about Svipdag's disinclination to perform the task imposed on him by his stepmother. This also gives us the key to Grogalder's words, that Svipdag was commanded to go and find not only "the one fond of ornaments," but "those fond of ornaments" (koma móti Menglödum). The plural indicates that there is more than one "fond of ornaments" to be sought. It is necessary to bring back to Asgard not only Freyja, but also Frey her brother, the god of the harvests, for whom the ancient artists made ornaments, and who as a symbol of nature is the one under whose supremacy the forces of vegetation in nature decorate the meadows with grass and the fields with grain. He, too, with his sister, was in the power of the giant-world in the great fimbul-winter (see below).
The food to which serpents must contribute one of the constituent parts reappears in Saxo's account of Hotherus (Hist., 123; No. 101), and is there described with about the same words. In both passages three serpents are required for the purpose. That Balder should be nourished with this sort of food is highly improbable. The serpent food in the stories about Hotherus and Ericus has been borrowed from the Svipdag-myth.
