Sigurd, still fearing that his secret might be revealed, kept the boy away from the court so that he might not be seen. But for all his care the danger was for ever recurring.

King Valdemar had a mother named Gerda, who was so old and infirm that she always lay abed. She was wonderfully skilled in spaedom, and it was always the custom at yuletide, when the guests a.s.sembled in the king's hall, that his mother was borne in thither and placed in the high seat.

There she prophesied touching any danger overhanging the country, or similar thing, according to the questions put to her.

Now it happened in the first winter of Olaf's being in Holmgard, that at the yule feast, when Gerda had been borne in after this fashion, Valdemar asked her whether any foreign prince or warrior would enter his dominions or turn his arms against his kingdom during the following year.

The old mother ran her bent fingers through the thin locks of her white hair, and gazing with dim eyes into the vast hall, thus spoke her prophecy:

"No token of any disastrous war do I discern," she said, "nor any other misfortune. But one wondrous event I see. In the land of Norway there has lately been born a child who will be bred up here, in Holmgard, until he grows to be a famous prince; one so highly gifted that there has never before been seen his equal. He will do no harm to this kingdom; but he will in every way increase thy fame. He will return to his native land while yet he is in the flower of his age, and he will reign with great glory in this northern part of the world. But not for long, not for long. Now, carry me away."

While these words were being spoken, Queen Allogia's eyes rested upon Olaf Triggvison, who was acting as cup bearer to his uncle Sigurd. She saw the drinking horn tremble in his hand, so that the wine it held dripped over the silver rim, and fell upon the front of his white kirtle; and she divined that it was to him that the prophecy referred.

But no sign of this suspicion did she betray, either at that time or in the after days. Yet none the less she watched him always, with her mind fixed upon the thought of his n.o.bility, and the glory that had been promised him. In all that he did she was well pleased, for already she had found that he excelled all others of his age, not only in personal beauty but in skilful handling of all warlike weapons, in the training of dogs and horses, in wrestling and riding, in racing on snowshoes, and in all other exercises. Often she would have spoken with him, but, saving at the time of a great feast, he was never to be seen in the hall.

Throughout the long, cold winter months, Olaf saw nothing of his foster brother or of Egbert the Briton, for they had both been taken across the river to labour on one of the king's farmsteads. There they remained until the early summer, when they brought over their flocks and herds for the sheep meeting. At that time there was held a great fair in Holmgard, with sports and games and manly contests. Many parties of men came into the town from distant parts of the kingdom.

On the second morning of the fair, Sigurd Erikson entered the room in which Olaf slept. The boy was dressing himself in his fine clothes, and girding on his leather belt with its small war axe, which Sigurd had had made for his young kinsman.

"My boy," said Sigurd, "there is little need for you to dress yourself in this holiday attire, for it is my will that you do not attend the games. You must not show yourself amid the crowd."

Now, Olaf had engaged to take part in a great wrestling bout with three young champions from Livonia. Also, he was to have run in a footrace, for which the prize was a silver hilted sword, awarded by the queen. So at hearing his uncle thus forbid him to appear, he became very indignant.

"It is too late for you to try to keep me within doors," he protested.

"I have given my word to the wrestlers, and I cannot now withdraw. Do you wish me to be jeered at as a coward? Why do you deny me the honour of taking all the prizes that I may so easily win?"

"It is for your own happiness that I forbid you to show yourself before strangers," returned Sigurd. "But, more than all, I wish you to keep in hiding for this great reason. There has come into Holmgard a man whom I met many months ago. I engaged with him to pit my best horse against his in the horse ring, and the prize was to be--"

"What was the prize?" asked Olaf, seeing that his uncle had paused.

"The prize was to be yourself, my son," said Sigurd gravely. "The man coveted you, and would have bought you from your old master Reas."

"And why did you agree to this, knowing that I am your own kinsman and your sister's son?" asked Olaf.

"I did not then know that you were of my kin," answered Sigurd. "But having given my word, I cannot go back from it. I have seen this man's horse, and I judge it to be a finer animal than mine. Therefore do I fear that I must lose you. But if you will keep within the house, I will tell the man that you are dead, and will offer him the young Englander Egbert in your stead."

"Would you then tell the man a falsehood?" cried Olaf.

"Gladly, if by doing so I still keep you with me, for I would not lose you for all the world."

Olaf, obedient to his uncle's word, began to unbuckle his belt. But his face was very gloomy, and it was easy to see that it was only out of his love for his uncle that he would by any means agree to forego his pleasures. Olaf was already very proud of his own skill. Never yet had he been beaten in any contest, and he had hoped to add to his glory by overcoming all who might come against him on this great day. Moreover, it was a sorry sacrifice for him to make if he was not to be allowed to witness the games.

As Sigurd turned to leave him, the boy suddenly caught his arm.

"I will not promise!" he cried. "I cannot give you my word. I have set my heart upon the wrestling, and in spite of your forbiddance I shall go. Tell me what manner of man this is that you speak of, and I will avoid him. Even though he overcome you in the horse fight he shall not take me from you."

"He is a great viking," answered Sigurd. "Men name him Klerkon Flatface. It is the same who sold you into bondage."

A cloud came upon Olaf's brow, and he sat down upon the side of the trestle bed.

"Klerkon Flatface?" he repeated slowly. Then raising his eyes he looked into his uncle's face and added: "Do not fear, hersir. Klerkon shall not take me from you."

Now, very soon after Sigurd had gone out to attend upon the king, Olaf quitted the house and went by secret ways to the stables, where he found his foster brother at work combing out the mane of Sigurd's fighting steed. A very tall and powerful animal it was, with a glossy brown coat and a long tail that reached nearly to the ground. It was well trained, and many a well won fight had it fought. Sleipner was its name, and it was so called after the eight footed horse of Odin.

Olaf went to Thorgils' side and greeted him with friendly words. Then, when they had spoken for a while together, Olaf bent his head close to Thorgils' ear, and said he:

"I have news, brother."

"Ill news or good?" asked Thorgils.

"Judge for yourself," answered Olaf. "It is that our old enemy Klerkon the Viking has come into Holmgard, with many men and a mighty horse that is to be pitted against Sleipner."

Thorgils drew back with a sudden start.

"Then has our good time come," he cried. "Our vow of vengeance must be fulfilled. No longer are we little boys, weak of arm and failing in courage. Never again shall Klerkon sail the seas."

"And who will hinder him?" asked Olaf, looking the while into the other's brightened eyes.

"He shall be hindered by me," returned Thorgils. "With me alone must the vengeance rest, for it is not well that you, who stand so high in honour with the king and his court, should sully your white hands with blood. It was my father whom Klerkon slew that day upon the ship, and it is my part to avenge him."

Then Olaf shook his head.

"Not so shall it be," said he. "Thoralf was my own good foster father, and I am not afraid to face the man who sent him so cruelly to his death. I and not you shall bring the murderer to his bane."

"Rash that you always are!" cried Thorgils. "Will you never learn to be cautious? Keep your peace. If I should fail, then will it be your turn to avenge my death as our vow of foster brotherhood demands. Now bring me a good weapon, for I have none but an oak cudgel."

"You shall not want for a good weapon," said Olaf, and he drew a small sword from under his blue cloak and handed it to Thorgils. "Here is my new handsax. Take it, and use it to good purpose. But in the matter of Klerkon, it may be that I shall be before you. Odin be with you!"

CHAPTER IV: THE SLAYING OF KLERKON.

It was yet early in the forenoon when the games began. They were held on the great plain beyond the gate, where fences were raised as a girdle round the course. Upon the sunny side was the king's tent, where Valdemar and Allogia sat, attended by many guests and courtiers, among whom was Sigurd Erikson.

For a long while Sigurd, who sat near to the queen, was at his ease in the belief that young Olaf was keeping within doors, and he paid little heed to those who were within the ring. First there were jumping matches. Olaf did not join in these, for he was not yet tall enough to compete with full grown men, and there were no youths of his own height who were skilled enough to match him. Neither, for a like reason, did he take part in the sword feats. But at last it came to a trial of skill with the longbow. The bowmen were at the far end of the course, and their faces could not well be seen from the tent, even had Sigurd searched among them for the face of his wilful nephew. There was one, however, who saw better than he, and this was Queen Allogia.

She waited until it came to the turn of those who were younger than eighteen years, and then she watched with keen eyes. Among them she soon discerned the youth whom she sought; nor did she lose sight of him until his well aimed arrow shot full into the mark, and he was proclaimed the victor. Then, when Olaf came before the tent to make his obeisance, Sigurd saw him, and was very wroth, for he knew that Klerkon the Viking was among the king's guests.

Now, when Olaf was thus near, it seemed to Klerkon that the lad was not wholly a stranger to him. Indeed, had it not been for the long gold hair and the disguise of better clothing, he might have known him to be the same whom he had seen in the last summer playing at the knife feat on the gangplank of the viking ship. But Klerkon only admired the lad's skill with the longbow, and thought what a goodly warrior he would make. So having this in his mind, he watched Olaf closely when again the boy ran past in the footrace, leading his compet.i.tors by many yards.

And now, being first in the race, Olaf came once more before the tent, and the queen gave him his well won prize.

As he took the silver hilted sword from Allogia's hand, one of the vikings went to Klerkon's side, and said he:

"Master, this youth is the same who appeared in the last summer as a bond slave at the time when the Hersir Sigurd came on board of us. Was it not this same lad who was to be the prize in our horse fight?"

Then Klerkon fixed his eyes more keenly on the lad, and thought of him as he might be with his fair hair cropped short, and with a slave's white kirtle in place of the fine clothes he now wore.

"It is the same!" he answered. "And now I mind that someone told me it was he whom we captured among others many summers ago off Alland isle.

It was we who brought him into Esthonia. Much would I give to have him with us on our longship. And by the hammer of Thor, I swear that if I win him not over the horse fight, then I will take him by force!"
