Interesting in this connection is also his fondness for poetry and his skill as a scald. It is told that he sat up half the night with the blind Icelandic scald, Stuf Katson, and would not sleep as long as Stuf could recite to him. This little trait adds a vivid touch to his character and brings it closer to our sympathy and comprehension. As the leader of the opposition to Harold, Einar Thambarskelver had long been prominent. As the son-in-law of Earl Haakon, the friend of Earl Erik and the foster-father of King Magnus, he occupied an exceptional position and was highly respected. His personal qualities were also such as to increase the esteem with which he was regarded. In natural endowments he was fully King Harold's match, and in imperiousness and proud self-assertion he did not yield much to him. Moreover, he was well skilled in the law, and when the king, as often happened, demanded more of the peasants than was his right, Einar rose as the people's spokesman and checked the arbitrary exaction. It was not to be wondered at that Harold hated him, but it is a striking tribute to the esteem in which he was held, that the king refrained so long from molesting him. But rashness was not among Harold's faults. He was fully capable of forecasting the results of his actions. As yet he felt that too great a risk would be involved in an attempt to rid himself of his enemy, who lived on a war-footing and was prepared to meet emergencies. With a view to weakening his power, Harold, therefore, made the Icelander Ulf Uspaksson his liegeman, and gave him far greater fiefs in Tröndelag than Einar had. Again, in order to break the solid front of the tribal magnates in that part of the country and divide their interests, he married the beautiful Thora, the sister of Eystein Orre, of the great race of the Arnmodlings.[A] The king was not then divorced from his first wife, Queen Ellisif, and it has therefore been supposed, that Thora was only his mistress. But it is not likely that her proud kinsmen would have allowed her to occupy such a position,[B] and it appears that the title of queen was everywhere accorded her. It is therefore impossible to escape the conclusion that Harold had, at the same time, two lawful wives. [Footnote A: To this family belonged Finn Arnesson, who fought at St. Olaf's side at Stiklestad, and Kalf Arnesson, whom Magnus the Good exiled.] [Footnote B: See Munch: "Det Norske Folks Historie," ii., p. 180.]
