Note 24 — The Lay of Hymir
Henry Adams Bellows translation
Hill of the hair: head,—a thoroughly characteristic skaldic phrase. Brother of Fenrir: Mithgarthsorm was, like the wolf Fenrir and the goddess Hel, born to Loki and the giantess Angrbotha (cf. Voluspo, 39 and note), and I have translated this line accordingly; but the word used in the text has been guessed as meaning almost anything from “comrade” to “enemy.”
