It happened at the battle of Stiklestad, as before related, that King Olaf threw from him the sword called Hneiter when he received his wound. A Swedish man, who had broken his own sword, took it up, and fought with it. When this man escaped with the other fugitives he came to Svithjod, and went home to his house. From that time he kept the sword all his days, and afterwards his son, and so relation after relation; and when the sword shifted its owner, the one told to the other the name of the sword and where it came from.
A long time after, in the days of Kirjalax the emperor of Constantinople, when there was a great body of Varings in the town, it happened in the summer that the emperor was on a campaign, and lay in the camp with his army. The Varings who had the guard, and watched over the emperor, lay on the open plain without the camp. They changed the watch with each other in the night, and those who had been before on watch lay down and slept; but all completely armed.
It was their custom, when they went to sleep, that each should have his helmet on his head, his shield over him, sword under the head, and the right hand on the sword-handle. One of these comrades, whose lot it was to watch the latter part of the night, found, on awakening towards morning, that his sword was gone. He looked after it, and saw it lying on the flat plain at a distance from him.
He got up and took the sword, thinking that his comrades who had been on watch had taken the sword from him in a joke; but they all denied it. The same thing happened three nights. Then he wondered at it, as well as they who saw or heard of it; and people began to ask him how it could have happened.
He said that his sword was called Hneiter, and had belonged to King Olaf the Saint, who had himself carried it in the battle of Stiklestad; and he also related how the sword since that time had gone from one to another. This was told to the emperor, who called the man before him to whom the sword belonged, and gave him three times as much gold as the sword was worth; and the sword itself he had laid in Saint Olaf's church, which the Varings supported, where it has been ever since over the altar.
There was a lenderman of Norway while Harald Gille's sons, Eystein, Inge, and Sigurd lived, who was called Eindride Unge; and he was in Constantinople when these events took place. He told these circumstances in Norway, according to what Einar Skulason says in his song about King Olaf the Saint, in which these events are sung.
