The Laxdaela Saga, tr. by Muriel Press, , at sacred-texts.com
At that time there rose to honour among men in Thorness, the kinsmen of Thorstein, named Bork the Stout and his brother, Thorgrim. It was soon found out how these brothers would fain be the greatest men there, and were most highly accounted of. And when Thorstein found that out, he would not elbow them aside, and so made it known to people that he wished to change his abode, and take his household to Hrappstead, in Salmon-river-Dale. Thorstein Swart got ready to start after the spring Thing, but his cattle were driven round along the shore. Thorstein got on board a ferry-boat and took twelve men with him; and Thorarin, his son-in-law, and Osk, Thorstein's daughter, and Hild, her daughter, who was three years old, went with them too. Thorstein fell in with a high southwesterly gale, and they sailed up towards the roosts, and into that roost which is called Coal-chest-Roost, which is the biggest of the currents in Broadfirth. They made little way sailing, chiefly because the tide was ebbing, and the wind was not favourable, the weather being squally, with high wind when the squalls broke over, but with little wind between whiles. Thorstein steered, and had the braces of the sail round his shoulders, because the boat was blocked up with goods, chiefly piled-up chests, and the cargo was heaped up very high; but land was near about, while on the boat there was but little way, because of the raging current against them. Then they sailed on to a hidden rock, but were not wrecked. Thorstein bade them let down the sail as quickly as possible, and take punt poles to push off the ship. This shift was tried to no avail, because on either board the sea was so deep that the poles struck no bottom; so they were obliged to wait for the incoming tide, and now the water ebbs away under the ship. Throughout the day they saw a seal in the current larger by much than any others, and through the day it would be swimming round about the ship, with flappers none of the shortest, and to all of them it seemed that in him there were human eyes. Thorstein bade them shoot the seal, and they tried, but it came to nought. Now the tide rose; and just as the ship was getting afloat there broke upon them a violent squall, and the boat heeled over, and every one on board the boat was drowned, save one man, named Gudmund, who drifted ashore with some timber. The place where he was washed up was afterwards called Gudmund's Isles. Gudrid, whom Thorkell Trefill had for wife, was entitled to the inheritance left by Thorstein, her father. These tidings spread far and near of the drowning of Thorstein Swart, and the men who were lost there. Thorkell sent straightway for the man Gudmund, who had been washed ashore, and when he came and met Thorkell, he (Thorkell) struck a bargain with him, to the end that he should tell the story of the loss of lives even as he (Thorkell) was going to dictate it to him. Gudmund agreed. Thorkell now asked him to tell the story of this mishap in the hearing of a good many people.
Then Gudmund spake on this wise: "Thorstein was drowned first, and then his son-in-law, Thorarin." -- so that then it was the turn of Hild to come in for the money, as she was the daughter of Thorarin. Then he said the maiden was drowned, because the next in inheritance to her was Osk, her mother, and she lost her life the last of them, so that all the money thus came to Thorkell Trefill, in that his wife Gudrid must take inheritance after her sister. Now this tale is spread abroad by Thorkell and his men; but Gudmund ere this had told the tale in somewhat another way. Now the kinsmen of Thorarin misdoubted this tale somewhat, and said they would not believe it unproved, and claimed one half of the heritage against Thorkell; but Thorkell maintained it belonged to him alone, and bade that ordeal should be taken on the matter, according to their custom. This was the ordeal at that time, that men had had to pass under "earth-chain", which was a slip of sward cut loose from the soil, but both ends thereof were left adhering to the earth, and the man who should go through with the ordeal should walk thereunder. Thorkell Trefill now had some misgivings himself as to whether the deaths of the people had indeed taken place as he and Gudmund had said the second time. Heathen men deemed that on them rested no less responsibility when ceremonies of this kind had to be gone through than Christian men do when ordeals are decreed. He who passed under "earth-chain" cleared himself if the sward-slip did not fall down upon him. Thorkell made an arrangement with two men that they should feign quarrelling over something or another, and be close to the spot when the ordeal was being gone through with, and touch the sward-slip so unmistakably that all men might see that it was they who knocked it down. After this comes forward he who was to go through with the ordeal, and at the nick of time when he had got under the "earth-chain", these men who had been put up to it fall on each other with weapons, meeting close to the arch of the sward-slip, and lie there fallen, and down tumbles the "earth-chain", as was likely enough. Then men rush up between them and part them, which was easy enough, for they fought with no mind to do any harm. Thorkell Trefill then asked people as to what they thought about the ordeal, and all his men now said that it would have turned out all right if no one had spoilt it. Then Thorkell took all the chattels to himself, but the land at Hrappstead was left to lie fallow.
