Skene's view is that it chronicles the struggle in 900 between Sigurd, earl of Orkney, and Maelbrigd, Maormor of Moray.
In IIIo, for example, he was enabled to capture Sidon by the aid of Sigurd of Norway, the Jorsalafari, who came to the Holy Land with a fleet of 55 ships, starting in 1107, and in a three years' "wandering," after the old Norse fashion, fighting the Moors in Spain, and fraternizing with the Normans in Sicily.
According to the Scandinavian story Sigmundr was slain in battle before the birth of Sigurd, but the German story makes him survive his son.
Sigurd acquired great fame and riches by slaying the dragon Fafnir, but the chief interest of the story centres round his connexion with the court of the Burgundian king Gunnar (Gunther).
A quarrel arose between Brynhildr and GuOrun, in the course of which the former learnt of the deception which had been practised upon her and this led eventually to the murder of Sigurd.
