Olaf the Glorious A Story of the Viking Age by Leighton, Robert, -1934

"Thus did the sons of Gunnhild clear their path. Thus, too, did the wicked queen fulfil the vow that she had sworn many years before, to exterminate the whole race of Harald Fairhair outside her husband's line.

"But," added Sigurd, in a deep and solemn voice, "the flower that is trampled under foot may yet leave its seed behind to come forth in its own season and flourish. The race of King Harald was not yet dead, and Queen Gunnhild presently found that there was a woman in Norway whose true love and faithfulness were better than all the guile and treachery that jealousy could devise. Triggvi Olafson's widow, Queen Astrid, when she heard tidings of his murder, guessed rightly that Gunnhild would pursue her, so she fled from Viken, and journeyed north towards the Uplands, taking with her her two young daughters, Ingibiorg and Astrid, together with such chattels as she might have with her. In her company was her foster father, Thoralf Lusaskegg by name, and his young son Thorgils. Thoralf never left her, but guarded her always most faithfully, while other trusty men of hers went about spying for tidings of her foes.

"Now very soon Astrid heard that Gunnhild's sons were pursuing her with intent to kill her, so she let herself be hidden on a little island in the midst of a certain lake. There on that island her son was born, and she had him sprinkled with water and named Olaf, after his father's father."

Sigurd paused, and laying his hand on Olaf's shoulder, "This," said he, "is that same child, Olaf Triggvison, and he is the one true flower of which King Harald Fairhair was the parent stem. An ill thing would it be for Norway if, for the slaying of Klerkon the Viking, he were now to lose his life. And I beg you, oh, queen! to deal kindly with this king's son so hardly dealt with, and to deal with King Valdemar concerning him that his life may be spared."

Then Queen Allogia answered, looking on the lad, that she would do as Sigurd wished.

"And now," she added, "tell me how it came to pass that the boy was ever brought across the sea to Esthonia."

So Sigurd told how Queen Astrid journeyed farther into the Uplands until she came to her father's manor at Ofrestead; how, dwelling there, she had been at last discovered by Gunnhild's spies, and been forced to take flight that she might save young Olaf from their murderous hands. For Gunnhild had now heard of the birth of this son of King Triggvi, and nothing would content her, but that he should die ere he could grow up to manhood, and so dispute with her own sons the realm that they now usurped.

He told how Queen Astrid, leaving her two daughters at Ofrestead, had fared east away into Sweden, and of what privations she had borne for her son's sake, and of how, still pursued by her enemies, she had at length taken safe refuge with Hakon Gamle, a friend of her father's.
