The story of Kilhuch and a maiden named Olwen

Shortly after the birth of Kilhuch, the son of King Kilyth, his mother died. Before her death she charged the king that he should not take a wife again until he saw a briar with two blossoms upon her grave, and the king sent every morning to see if anything were growing thereon. After many years the briar appeared, and he took to wife the widow of King Doged. She foretold to her stepson, Kilhuch, that it was his destiny to marry a maiden named Olwen, or none other, and he, at his father's bidding, went to the court of his cousin, King Arthur, to ask as a boon the hand of the maiden. He rode upon a grey steed with shell-formed hoofs, having a bridle of linked gold, and a saddle also of gold. In his hand were two spears of silver, well-tempered, headed with steel, of an edge to wound the wind and cause blood to flow, and swifter than the fall of the dew-drop from the blade of reed grass upon the earth when the dew of June is at its heaviest. A gold-hilted sword was on his thigh, and the blade was of gold, having inlaid upon it a cross of the hue of the lightning of heaven. Two brindled, white-breasted greyhounds, with strong collars of rubies, sported round him, and his courser cast up four sods with its four hoofs like four swallows about his head. Upon the steed was a four-cornered cloth of purple, and an apple of gold was at each corner. Precious gold was upon the stirrups and shoes, and the blade of grass bent not beneath them, so light was the courser's tread as he went towards the gate of King Arthur's palace. OLWEN Arthur received him with great ceremony, and asked him to remain at the palace; but the youth replied that he came not to consume meat and drink, but to ask a boon of the king. Then said Arthur, "Since thou wilt not remain here, chieftain, thou shalt receive the boon, whatsoever thy tongue may name, as far as the wind dries and the rain moistens, and the sun revolves, and the sea encircles, and the earth extends, save only my ships and my mantle, my sword, my lance, my shield, my dagger, and Guinevere my wife." So Kilhuch craved of him the hand of Olwen, the daughter of Yspathaden Penkawr, and also asked the favour and aid of all Arthur's court. Then said Arthur, "O chieftain, I have never heard of the maiden of whom thou speakest, nor of her kindred, but I will gladly send messengers in search of her." And the youth said, "I will willingly grant from this night to that at the end of the year to do so." Then Arthur sent messengers to every land within his dominions to seek for the maiden; and at the end of the year Arthur's messengers returned without having gained any knowledge or information concerning Olwen more than on the first day. Then said Kilhuch, "Every one has received his boon, and I yet lack mine. I will depart and bear away thy honour with me." Then said Kay, "Rash chieftain! dost thou reproach Arthur? Go with us, and we will not part until thou dost either confess that the maiden exists not in the world, or until we obtain her." Thereupon Kay rose up. Kay had this peculiarity, that his breath lasted nine nights and nine days under water, and he could exist nine nights and nine days without sleep. A wound from Kay's sword no physician could heal. Very subtle was Kay. When it pleased him he could render himself as tall as the highest tree in the forest. And he had another peculiarity--so great was the heat of his nature, that, when it rained hardest, whatever he carried remained dry for a handbreadth above and a handbreadth below his hand; and when his companions were coldest, it was to them as fuel with which to light their fire.
