Research Notes:
It is clear that the role of Sigrid in the stories of HEIMSKRINGLA is that of an explanation for the Battle of Svoldur. Adam of Bremen does not assign any role to Svein's wife in the outbreak of this war--and the narrative of HEIMSKRINGLA concerning why Denmark and Sweden went to war with Olaf Tryggvasson would make perfect sense whether or not Sigrid the Haughty appears in the story. Adam implies that the "haughty" woman who instigated hostilities was Svein's sister Thyri, not Svein's wife.
It seems that the role and reputation of Svein's sister Thyri became grafted onto Svein's wife. Combined with the error concerning which wife of Erik the Victorious afterwards married Svein Forkedbeard, and we get a woman who is haughty, and who is remembered for her marriages, especially to kings. This reputation is *probably* responsible for the story of the way that she burned Harald Grenski and Vsevolod to death in retaliation for their proposing to her. [Ref: Jared Olar SGM 6/4/1996]
