When Haldor, a son of Brynjolf Ulfalde the Old, who was a sensible man and a great chief, heard people talk of how unlike the brothers Saint Olaf and King Harald were in disposition, he used to say,
"I was in great friendship with both the brothers, and I knew intimately the dispositions of both, and never did I know two men more like in disposition.
Both were of the highest understanding, and bold in arms, and greedy of power and property; of great courage, but not acquainted with the way of winning the favour of the people; zealous in governing, and severe in their revenge.
King Olaf forced the people into Christianity and good customs, and punished cruelly those who disobeyed. This just and rightful severity the chiefs of the country could not bear, but raised an army against him, and killed him in his own kingdom; and therefore he is held to be a saint.
King Harald, again, marauded to obtain glory and power, forced all the people he could under his power, and died in another king's dominions.
Both brothers, in daily life, were of a worthy and considerate manner of living; they were of great experience, and very laborious, and were known and celebrated far and wide for these qualities."
