Then the lady wept, and answered: "All my three and twenty sons have been killed by Thornogre Thistlehair, Chief of the Giants; and now my only hope of keeping him alive is to hide him in this chest, where he has lived ever since he was born." And she wept to think that her boy would never have a chance of doing valiant deeds and of becoming a great knight. Then Kai bade her be of good cheer and let the lad come with them, promising that he should not be slain unless he, Kai, were killed as well. She agreed to this very gladly, and asked them why they had come to that region. But when she knew they had come to seek for Olwen, she advised them strongly to go home, since in that very quest all her three and twenty sons had perished. They laughed at her fears, however, and asked if the maiden ever came to the shepherd's house. "Yes," said the shepherd's wife; "she comes every Saturday to wash her hair. She leaves behind her all her jewels and rings in the water which she uses, and never asks for them again." Then they begged her to ask fair Olwen to visit her at once, and she agreed, on condition that they would not carry her off against her will. To this the Champions agreed, and sat waiting in a hall for the coming of the maiden. Very fair she looked as she approached, dressed in a robe of flame-coloured silk, and wearing a jewelled collar of gold round her neck. More yellow was her hair than the flower of the broom, and her skin was whiter than the foam of the wave; and fairer were her hands and fingers than the blossoms of the wood-anemone amidst the spray of the meadow fountain. The eye of the trained hawk, the glance of the falcon were not brighter than hers. Her bosom was more snowy than the breast of the white swan; her cheek was redder than the reddest roses. Whoso beheld her was filled with love of her. Four white trefoils sprang up wherever she trod; therefore was she called Olwen of the White Footprints. Having entered the house she sat down by Kilhugh, who at once loved her greatly, and began to pray her to come away with him, and be his wife. But Olwen, though she returned his affection, answered that she had promised her father not to go away without his leave. She also told him that Thornogre knew that her bridal day was fated to be the day of his death, so that he would withhold his leave as long as possible. She advised him, however, to go to her father, and to grant him everything he demanded, and so in time he should win her hand; but if he denied the giant's least request, he would lose both her and his own life. When she had said this, she returned to the castle. III. The Impossible Tasks set by Thornogre Thistlehair The Seven Champions now determined to make their way to the castle, and force an entrance to the hall of Thornogre Thistlehair, Chief of the Giants. It was very dark when they set out, but they easily found their way by the trail of white trefoils which the footprints of Olwen had left.
