“Well, when they got half-way to Mafvahlið, came Geirrid to meet them, with her workmen. ‘They had not gone the right way to work in seeking Odd,’ she said, ‘but she would help them.’ So they turned back again. Geirrid had a blue cloak on her. Now when the party was seen and reported to Katla, and it was said that they were thirteen in number, and one had on a coloured dress, Katla exclaimed, ‘That troll Geirrid is come! I shall not be able to throw a glamour over their eyes any more.’ She started up from her place and lifted the cushion of the seat, and there was a hole and a cavity beneath: into this she thrust Odd, clapped the cushion over him, and sat down, saying she felt sick at heart. “Now when they came into the room, there were small greetings. Geirrid cast of her the cloak and went up to Katla, and took the seal-skin bag which she had in her hand, and drew it over the head of Katla.[1] Then Geirrid bade them break up the seat. They did so, and found Odd. Him they took and carried to Buland’s head, where they hanged him. . . . But Katla they stoned to death under the headland.” [1] A precaution against the “evil eye.” Compare _Gisla Saga Surssonnar_, p. 34. _Laxdæla Saga_, cc. 37, 38. CHAPTER IV. THE ORIGIN OF THE SCANDINAVIAN WERE-WOLF. Advantage of the Study of Norse Literature—Bear and Wolf-skin Dresses—The Berserkir—Their Rage—The Story of Thorir—Passages from the Aigla—The Evening Wolf—Skallagrim and his Son—Derivation of the Words Hamr and Vargr—Laws affecting Outlaws—“To become a Boar”—Recapitulation. One Of the great advantages of the study of old Norse or Icelandic literature is the insight given by it into the origin of world-wide superstitions. Norse tradition is transparent as glacier ice, and its origin is as unmistakable. Mediæval mythology, rich and gorgeous, is a compound like Corinthian brass, into which many pure ores have been fused, or it is a full turbid river drawn from numerous feeders, which had their sources in remote climes. It is a blending of primæval Keltic, Teutonic, Scandinavian, Italic, and Arab traditions, each adding a beauty, each yielding a charm, bat each accretion rendering the analysis more difficult.
