Now it is said that Loki got to know that Freyja had received the necklace ... and this he told to Othin. And when Othin heard of it he told Loki to fetch him the necklace. Loki said that there was not much hope of that, because no-one could get into Freyja's bower against her will. Othin told him to go, and not come back without the necklace. So Loki went off howling, and everyone was glad that he had got into trouble.
He went to Freyja's bower, but it was locked. He tried to get in but could not. The weather outside was very cold and he became thoroughly chilled. Then he turned himself into a fly, and flew around all the bolts and along the whole of the woodwork, but nowhere could he find a hole big enough to enter by, right up to the gable. He found only a hole no bigger than would allow of the insertion of a needle. Through this hole he crept. And when he got inside he stared around, wondering if anyone was awake. But he found that the room was all wrapped in slumber.
Then he went in and up to Freyja's bed and found that she was wearing the necklace and that the clasp was underneath her. Loki thereupon turned himself into a flea and settled on Freyja's cheek and stung her, till she awoke and turned over and went to sleep again. Then he laid aside his flea-form, drew the necklace from her gently, opened the door and departed, carrying the necklace to Othin.
When Freyja awoke in the morning she found that the door was open, though it had not been forced, and that her lovely necklace was gone. She had a shrewd idea of the trick that had been played on her, and when she was dressed she went into the hall to King Othin, and told him that he had done ill to rob her of her trinket, and begged him to return it.
Othin replied that considering how she had come by it she should never get it back:
"—Unless you bring about a quarrel between two kings, each of whom has twenty kings subject to him; so that they shall fight under the influence of such spells and charms that as fast as they fall they shall start up again and fight on—unless there be some Christian man so brave and so much favoured by the great good fortune of his liege lord that he shall dare to take arms and enter among the combatants and slay them. Then and not till then shall the labours of those princes be brought to an end—whoever may be the chief who is destined to free them from the oppression and toil of their disastrous lot."
Freyja agreed to this and recovered the necklace.
III.[°] Four and twenty years after the death of Frithfrothi a King called Erling ruled over the Highlands of Norway. He had a wife and two sons, of whom the elder was called Sörli the Strong, and the younger Erlend. They were promising young men. Sörli was the stronger of the two. As soon as they were old enough they took to raiding, and fought against the viking Sindri, the son of Sveigir, the son of Haki, a sea-king in the Skerries of the Elf. There fell Sindri the viking, and with him all his host; and Erlend the son of Erling also fell in that battle. After that Sörli sailed into the Baltic and harried there, and performed so many great deeds that it would take too long to recount them all.
