[7, 8] tveimr jǫfrum ‘two princes’: The reference is no doubt to Ǫnundr Óláfsson and Óláfr Haraldsson, though it is clear from the reference in the ASC (‘E’) s. a. 1025 to a certain Ulf and Eglaf (Eilífr, or perhaps an error for Óláfr) that an assortment of Swedish and Norwegian nobles opposed Knútr at the battle.
