[2] bróðir Haralds ‘brother of Haraldr’: The sense of the helmingr makes it clear that bróðir is the subject of the sentence, and the nom. form of the word in Bb must be the correct reading. The epithet for Óláfr refers to his half-brother Haraldr Sigurðarson (Haraldr harðráði ‘the Hard-ruler’), the son of Óláfr’s mother and step-father, Sigurðr sýr ‘Sow’. Haraldr fought alongside Óláfr at Stiklestad, and was sole king in Norway after Magnús the Good (1047-66). He died in the battle of Stamford Bridge.
