  • Olaf the Glorious: A Story of the Viking Age

    Robert Leighton

    eBook (Open Road Media, April 21, 2020)
    The epic life saga of the tenth-century king of Norway from the British author of The Thirsty Sword and other historical adventures. Norse history comes alive in this story of a Viking who became a king. Though he had a humble start in life—orphaned as a child and sold into slavery—Olaf became known for bringing the Roman Catholic religion to the early Norwegians. Olaf’s heroic life—from his time in King Valdemar’s court to his Viking exploits and battles to his ascension to the throne of his native land—has been heralded in Icelandic sagas. These provided the inspiration for nineteenth-century author Robert Leighton’s historical novel of Middle Age valor and glory.

  • Olaf the Glorious A Story of the Viking Age

    Robert Leighton

    eBook (, May 4, 2014)
    Olaf the Glorious, A Story of the Viking Age is a biographical novel about Olaf I king of Norway, written in 1929 by Robert Leighton.So Olaf quitted Holmgard and went on shipboard, and stood out with his viking fleet into the Baltic Sea. He now owed no allegiance to any man, but was free to journey where he pleased, a king upon his own decks. At this time he was scarcely eighteen summers old; but his limbs were so well knit and strong, and he was withal so tall and manly, that he seemed already to have attained to man's estate. Yet, feeling that his youth might be against him, he had chosen that all his ship companions should be as near as possible to his own age. He had a score or so of bearded berserks on each of his ships--men who feared neither fire nor steel, but who gloried in warfare, and loved nothing better than to be in the midst of a great battle. These indeed were full aged men; but for the rest, his crew of seamen and his band of trained men-at-arms was comprised of youths, none of whom were older than Thorgils Thoralfson, or younger than Olaf himself.Olaf made his foster brother the chief in command under himself, giving him power over both seamen and warriors. He made his friend Egbert the sailing master, while one Kolbiorn Stallare became his master-of-arms.Kolbiorn was the son of a powerful viking of Sognfiord in Norway. He was of an age with Olaf Triggvison, and so much did the two resemble one the other that, when apart, they were often taken to be brothers. Both had the long fair hair and the blue eyes of the Norseland, both were of nearly equal height; and it was Kolbiorn's habit to strive, by wearing similar clothing, to increase the likeness between himself and his young master. But when the two were side by side the resemblance ceased, for then Olaf was seen to be both the taller and the more muscular; his hair was seen to be more golden and silken, his skin more purely fair; his eyes, too, were brighter and larger than those of Kolbiorn, and his teeth more even and white. So, too, when it came to a test of skill, Olaf had ever the advantage, notwithstanding that Kolbiorn had spent all his young days on shipboard, had been taught by the vikings to perform all manner of feats, and had taken part in many battles on both land and sea.On a certain calm morning, very soon after Olaf had set out on this his first viking cruise, he stood with Kolbiorn at the ship's rail, looking out over the sunlit sea as his vessel crept along propelled by her forty long, sweeping oars, and followed by his four longships."I think," said he, "that we will amuse ourselves today, and try our skill in some new game.""I am very unfit to try my skill against yours," returned Kolbiorn modestly, "for you have already beaten me at chess, at swimming, at shooting, and at throwing the spear. Nevertheless, it shall be as you wish.""Choose, then, what feat we are to perform," said Olaf; "I am willing to join in any exercise that you may know, and I do not doubt that there are many in which your skill must be greater than mine.""There is one," said Kolbiorn, "that I would be glad to see you attempt, although there is danger in it, and I may be doing wrong in suggesting it.""If it be new to me, then I shall be all the more pleased," said Olaf; "and none the less so though the risk be great."Kolbiorn drew the young commander across to the shady side of the ship."It is that we shall climb over the bulwarks," said he, "and walk outboard along the oars while the men are rowing."Olaf looked over the side, and for a few moments watched the regular motion of the oars as they dipped into the green water and rose dripping into the air. He measured with his eye the space between each of the twenty blades."It seems not so difficult as I had hoped," he said, "but let me see you do it, and then I will follow."
