The dating has never been a matter of controversy. It is inferred from the internal chronology of the sources themselves and the dating of Hygelac's raid on Frisia to c. 516. It is also supported by archaeological excavations of the barrows of Eadgils and Ohthere in Sweden. For a discussion, see e.g. Birger Nerman's Det svenska rikets uppkomst (1925) (in Swedish). For presentations of the archaeological findings, see e.g. Elisabeth Klingmark's Gamla Uppsala, Svenska kulturminnen 59, Riksantikvarieämbetet (in Swedish), or this English language presentation by the Swedish National Heritage BoardArchived 2007-08-24 at the Wayback Machine
