 As reconstructed by Finnur Jónsson, most of the central narrative content of the poem is preserved in the kings' sagas; Fagrskinna, Heimskringla, Óláfs saga Tryggvasonar en mesta and Flateyjarbók.Finnur believed that verses preserved in Skáldskaparmál, where Hákon is directly addressed, belong to the beginning
and end of the poem.Two lines are also preserved in the Third Grammatical Treatise.
