"I have two sons," replied the Earl, "who went yesterday to hunt upon the mountains. But on the mountains lives an evil monster who kills men and devours them, and he has seized my sons; and to-morrow he will bring them here, and will devour them before my eyes, unless I will deliver my sweet daughter into his hands. He has the form of a man, but the strength of a giant, and no one can do aught against him." "Truly this is a hard case," said Owain. "And what wilt thou do?" "Heaven knows," said the Earl. "But I can never give up my young daughter to be destroyed by him; yet I cannot bear to lose my two brave sons." So no more was said, and Owain stayed there that night. Next morning a great noise was heard as the giant entered the courtyard, dragging behind him the two youths by the hair of their heads. Then Owain put on his armour, and went out to fight the giant, and the lion followed him. The giant made a great rush upon the knight; and the lion fought on Owain's side, more fiercely than his master. At length the giant said: "I could easily settle this business with you were it not for the animal that is with you." So Owain shut the lion up inside the castle walls, and went back to fight the giant as before. But the lion heard that it was going ill with Owain; and he roared very loud, and climbed up till he reached the top of the castle, and then sprang down from the walls, and joined his master. And very soon he gave the giant such a stroke with his paw that the monster fell down dead. Then the Earl was full of gratitude, and begged Owain to remain with him; but he would only stay one more night, and on the morrow set out for the meadow where Luned was imprisoned in the mound. When he reached the spot, he found a great fire kindled, and two youths with curling auburn hair were leading the maiden forth to cast her in the fire. [Illustration: "TWO YOUTHS WERE LEADING THE MAIDEN FORTH"] "Why are you treating her thus?" asked Owain. They told him of the compact that was between them concerning the maiden. "Owain has failed her," said they, "therefore she must be burnt according to our agreement." "Well," said Owain, "I know him for a good knight, and if he had known of the maiden's peril he would have come to her rescue; but if you will accept me in his stead I will do battle for her."
