The Story of Norway by Hjalmar Hjorth Boysen

While Harold's despotism had been civilizing and, on the whole, beneficent, that of Erik Blood-Axe was disorganizing and destructive. With him the old turbulent viking spirit ascended the throne. Power meant with him the means of gratifying every savage impulse. Brave he was, delighting in battle; cruel and pitiless; and yet not without a certain sense of fairness and occasional impulses of generosity. In person he was handsome, of stately presence, but haughty and taciturn. Unhappily he married a woman who weakened all that was good in him and strengthened all that was bad. Queen Gunhild possessed a baneful influence over him during his entire life. She was cruel, avaricious, and treacherous, and was popularly credited with all the ill deeds which her husband committed. There are strange legends about her, attributing to witchcraft the power she had over every one who came in contact with her.

According to Snorre, Erik met her in Finmark, whither she had been sent by her parents to learn sorcery. For the Finns were in those days credited with a deep knowledge of the black art. The two sorcerers with whom she was staying were both determined to marry her, and like the princess in the fairy-tale, she concealed Prince Erik in her tent, and begged him to rid her of her troublesome suitors. This, in spite of many difficulties, Erik did, carried Gunhild away to his ships, and made her his wife. She was, it is said, small of stature, insinuating, and of extraordinary beauty; but she was the evil genius of her husband, egging him on to deeds of treachery and violence which made him detested by his people.
