So the maiden tended Owain, and gave him meat and drink and medicine until he was well again. And in three months he was as comely a knight as ever he had been before. One day he heard a great tumult in the castle, and asked the maiden the cause thereof. She told him that the earl whom she had mentioned before had come against the Countess with a large army to force her to marry him. "Has she a horse and arms to spare?" asked Owain. "She has the best in the world," said she.

"Then go and beg the loan of them," said Owain, "that I may go and have a look at this earl." "I will," said the maiden. So she made her request to the Countess; but the lady laughed a bitter laugh, and said: "He may as well have them to-day as my enemy to-morrow; but I know not what he would do with them."

Then they brought out a beautiful black horse, with a beechen saddle, and a suit of armour for man and horse; and Owain armed himself, and rode forth, attended by two pages. When they came in sight of the enemy they could not see where the army ended, it was so great; but Owain asked where the earl himself was, and when he was pointed out, he sent the pages back to the castle, and rode forward till he met the earl. And Owain was now so strong that he drew the earl completely out of the saddle, and turned his horse's head towards the castle, and, although it was no easy task, brought the earl to the gate. When they had entered, he gave the earl as a gift to the Countess, and said to her: "Lo, here is a return to you for your wondrous balsam."

Then the earl restored to the Countess her two earldoms in ransom for his life, and for his freedom he gave her half his own domains and all his jewels and gold and silver.

After this Owain departed from the castle, though all honoured him greatly and begged him to stay with them. But he was still ashamed and sorrowful at heart, and preferred rather to ride forth into desert places again.

One day, as he was journeying through a wood, he heard a great uproar, and, riding forward, found a great craggy mound, on the side of which was a grey rock. In the rock was a cleft, and in the cleft a serpent; and near by stood a black lion, and every time the lion moved to go hence the serpent darted towards him to attack him.

Then Owain unsheathed his sword, and struck the serpent, and cut him in two, and went on his way. But, strange to say, the lion followed him, and played about him like a dog. All that day they travelled together; and at night Owain dismounted, and turned his horse loose in a woody meadow. And he kindled a fire, the lion bringing him wood enough to last for three nights. Then the lion disappeared, and after a while returned bearing a fine, large roebuck, which he laid before Owain; and when it was skinned and roasted, it made an excellent supper for them both. As he was eating, he heard a deep sigh near him, which was repeated three times.

"Who is there?" asked Owain. "A mortal maiden," was the reply. "Who art thou?" he asked again. And the voice replied: "I am Luned, the handmaiden of the Countess of the Fountain. In this stone vault am I imprisoned on account of the knight who came from Arthur's Court and married my Countess. For a short time only he stayed with her, and then went away, and has never returned—and he was the friend I loved most in the world. And one day two of the pages of the Countess's chamber reviled him, and called him ill names, and I told them that they two were not a match for him alone. Then they imprisoned me in this stone cell, and said I should be put to death unless he came himself to deliver me by a certain day—and that is the day after to-morrow. But I have no one to send to seek him for me. And his name is Owain, the son of Urien."

Then Owain said: "Art thou certain that if the knight knew all this, he would come to your rescue?"

"I am most certain of it," said she.
