two rivals join battle, they both fall. Sigurd Ring is the father of Ragnar Lodbrok who has been brought up in Norway during the civil war, but is now hailed as Danish ruler. Other sources According to Hversu Noregr byggdist, Sigurd Ring is the son of Randver, the uterine brother of Harald Wartooth. Randver is the son of Raðbarðr while Harald is the son of Hrærekr slöngvanbaugi. In the part of the Heimskringla called the Saga of Harald Fairhair, Harald Fairhair learns that the Swedish king Erik Eymundsson had enlarged Sweden westwards, until it reached the same extent as it had during king Sigurd Ring and his son Ragnar Lodbrok.
