So Olaf got back eventually to the kingdom of his fathers, and "when he came north to Agdaness he heard that Earl Hakon was in the firth, and withal that he was at strife with the bonders. And when Thorir heard tell of these things, then were matters gone a far other way than he had been deeming; for after the battle with the Jomsburg vikings (notable pirates whose stronghold was in Pomerania) were all men of Norway utterly friendly to Earl Hakon for the victory he had gotten, and the deliverance of all the land from war; but now so ill had things turned out that here was the earl at strife with the bonders, and a great lord come into the land."
There was a man named Worm Lyrgia, a wealthy bonder, and he had to wife one who was known as the Sun of Lund, where her father dwelt; she was the fairest among women. Thralls came from the Earl of Ladir to carry her away by force, but Worm (despite his name) was a man of spirit and fire. He "let the war-arrow fare four ways through the countryside with this bidding withal, that all men should fall with weapons on Earl Hakon to slay him." This incident, which was far from being an isolated case, proved very unfortunate for the government of the earl; in fact, he soon became a fugitive with a single thrall, named Kark.
"Then he arose, and they went to the stead of Rimul, and the earl sent Kark to Thora, bidding her come privily to him. So did she, and welcomed the earl kindly, and he prayed her to hide him for certain nights till the gathering of the bonders went to pieces. Said she: 'They will be seeking thee here about my stead both within and without; for many wot that I would fain help thee all I may, but one place there is about my stead where I deem that I would not think of seeking for such a man as thou, a certain swine-sty to wit.'
"So they went thither: and the earl said: 'Make we ready here; for we must take heed to our lives first of all.' Then dug the thrall a deep hole therein, and bore away the mould, and then laid wood over it. Thora told the earl the tidings how Olaf Tryggvison was come into the mouth of the firth, and had slain Erland his son.
"Then went the earl into the hole and Kark with him, and Thora did it over with wood, and strawed over it mould and muck and drave the swine thereover. And this swine-sty was under a certain big stone."
So the bonders and Olaf fell straightway into good friendship, and the son of Tryggvi ascended the throne of his fathers. He was one of the greatest of the kings of the Norse, superior in many respects to his namesake, who is distinguished as the saint. The chief secret of his power is opened to us by the following passage from the Faereyinga Saga, for popularity in the viking age was gained by much the same qualities that secure it in an English Public School to-day. "Once in the spring King Olaf said to Sigmund. 'We will amuse ourselves to-day, and prove our feats of skill.' 'I am not the man for that, lord,' said Sigmund, 'but thou shalt have thy way in this as in all other things that are in my hands.' Then they tried their might in swimming and shooting and other feats of skill and strength, and men say that Sigmund came very nigh the king in many feats, albeit he came short of him in all, as did every other man that was then living in Norway."
To return to the swine-sty in the Heimskringla. Olaf came to seek the earl at Thora's stead as she had said he would. Then he "held a House-Thing out in the garth, and himself stood up on that same big stone that was beside the swine-sty.
"There spake Olaf to his men, and some deal of his speaking was that he would with wealth and worth further him who should bring Earl Hakon to harm.
"Now this talk heard the earl, and Kark, and they had a light there with them; and the earl said: 'Why art thou so pale, or whiles as black as earth? Is it not so that thou wilt bewray me?'
