There still remain one or two important passages in regard to the correct interpretation of the epithet Rogner. In Atlakvida (33) it is said of Gudrun when she goes to meet her husband Atle, who has returned home, carrying in her hand a golden goblet, that she goes to _reifa gjöld Rögnis_, "to present that requital or that revenge which Rogner gave." To avenge her brothers, Gudrun slew in Atle's absence the two young sons she had with him and made goblets of their skulls. Into one of these she poured the drink of welcome for Atle. A similar revenge is told about Volund. The latter secretly kills _Nidadr's_ two young sons and makes goblets out of their skulls for their father. In the passage it is stated that the revenge of Gudrun against Atle was of the same kind as Rogner's revenge against some one whom he owed a grudge. So far as our records contain any information, Volund is the only one to whom the epithet Rogner is applicable in this case. Of no one else is it reported that he took a revenge of such a kind that Gudrun's could be compared therewith. In all other passages the epithet Rogner refers to "the father of the swords," to the ancient artist Thjasse, the son of Alvalde. Here it refers to the father of the most excellent sword, to the ancient artist Volund, the son of Ivalde.
The strophe in Vellekla, which compares the Thjasse descendant Hakon Jarl with the hail-producing Rogner, also alludes to another point in the myth concerning him by a paraphrase the kernel of which is: _Varat svanglýjadi at frýja ofbyrjar nè drifu_, "it was impossible to defy the swan-pleaser in the matter of storm and bad weather." The paraphrase is made applicable to Hakon by making the "swan-pleaser" into the "pleaser of the swan of the sword's high-billowing fjord"--that is to say, the one who pleases the bird of the battlefield, that is, the raven. The storm is changed into "the storm of arrows," and the bad weather into the "bad weather of the goddess of the battle." The mythological kernel of this paraphrase, and that which sheds light on our theme, is the fact that Rogner in the mythology was "one who pleased the swans." In the heroic poem three swan-maids are devoted in their love to Volund and his brothers. Volundarkvida says that the third one lays her arms around Volund-Anund's white neck.
