 One view considers the account to have kept alive by the oral tradition of heroic poetry until it was included in the "epos".It has also been suggested that the poem is dependent on "Liber historiae Francorum" (727), because it mentions the "Attoarii", which in "Beowulf" become "Hetware".One scholar considers it to be inconceivable that independent oral tradition would have faithfully transmitted such a detail.
