In contrast, other historians have proposed that Rodulf had been kings of the list of seven peoples (Granii ... Rani), but most of these can not be identified with any confidence. Since Mommsen's edition of Jordanes, with index notes by Karl Müllenhof, there have been proposals connecting them to Norway. Some modern historians, mostly Norwegian, have continued to make such proposals and imply that Rodulf was a king of all seven of these peoples there. For example, the list has been interpreted as referring to the inhabitants of "Grenland, Halogaland, Telelmark, Ryfylkem, Hordaland, and Ranrike or Romsdal". The vast geographic distances between the tribes, scattered throughout the Norwegian coast, and the unlikeliness of a unified kingdom of such a magnitude at this early point has been cited as an argument against such a possibility.
