[12]. Instein: mentioned in the Halfssaga as one of the warriors of King Half of Horthaland (the so-called Halfsrekkar). The others mentioned in this stanza appear in one of the later mythical accounts of the settlement of Norway.
[14]. Stanzas 14–16 are clearly interpolated, as Friaut (stanza 13, line 3) is the daughter of Hildigun (stanza 17, line 1). Halfdan the Old, a mythical king of Denmark, called by Snorri “the most famous of all kings,” of whom it was foretold that “for three hundred years there should be no woman and no man in his line who was not of great repute.” After the slaying of Sigtrygg he married Almveig (or Alvig), daughter of King Eymund of Holmgarth (i.e., Russia), who bore him eighteen [[223]]sons, nine at one birth. These nine were all slain, but the other nine were traditionally the ancestors of the most famous families in Northern hero lore.
[16]. Compare stanza 11. All or part of this stanza may be interpolated.
[17]. Hildigun (or Hildiguth): with this the poem returns to Ottar’s direct ancestry, Hildigun being Friaut’s mother. Line 4: cf. the refrain-line in the Voluspo (stanzas 27, 29, etc.).
[18]. Another interpolation, as Ketil (stanza 19, line 1) is the husband of Hildigun (stanza 17). Dag: one of Halfdan’s sons, and ancestor of the Döglings. Line 5 may be a late addition.
[19]. Ketil: the semi-mythical Ketil Hortha-Kari, from whom various Icelandic families traced their descent. Hoalf: probably King Half of Horthaland, hero of the Halfssaga, and son of Hjorleif and Hild (cf. stanza 12, note). [[224]]
[20]. Nanna: the manuscript has “Manna.” Of Nanna and her father, Nokkvi, we know nothing, but apparently Nanna’s son married a sister of Instein, Ottar’s father.
[21]. Olmoth: one of the sons of Ketil Hortha-Kari. Line 4: here, and generally hereafter when it appears in the poem, this refrain-line is abbreviated in the manuscript to the word “all.”
[22]. An isolated stanza, which some editors place after stanza 24, others combining lines 1–2 with the fragmentary stanza 23. In the manuscript lines 3–4 stand after stanza 24, where they fail to connect clearly with anything. Hrolf the Old: probably King Hrolf Gautreksson of Gautland, in the saga relating to whom (Fornaldar sögur III, 57 ff.) appear the names of Thorir the Iron-shield and Grim Thorkelsson. [[225]]
[23]. Stanzas 23 and 24 name the twelve Berserkers, the sons of Arngrim and Eyfura, the story of whom is told in the Hervararsaga and the Orvar-Oddssaga. Saxo Grammaticus tells of the battle between them and Hjalmar and Orvar-Odd. Line 1 does not appear in the manuscript, but is added from the list of names given in the sagas. The Berserkers were wild warriors, distinguished above all by the fits of frenzy to which they were subject in battle; during these fits they howled like wild beasts, foamed at the mouth, and gnawed the iron rims of their shields. At such times they were proof against steel or fire, but when the fever abated they were weak. The etymology of the word berserk is disputed; probably, however, it means “bear-shirt.”
