"What is that?" said Owain.
"I have two sons," replied the earl, "and yesterday they went to the mountains to hunt. Now, there is on the mountain a monster who kills men and devours them; and he seized my sons. And to-morrow is the time he has fixed to be here; and he threatens that he will then slay my sons before my eyes unless I will deliver into his hands this my daughter. He has the form of a man; but in stature he is no less than a giant."
"Truly," said Owain, "that is lamentable. And which wilt thou do?"
"Heaven knows," said the earl, "it will be better that my sons should be slain against my will than that I should voluntarily give up my daughter to him to ill-treat and destroy."
Then they talked about other things; and Owain staid there that night.
The next morning they heard an exceeding great clamor, which was caused by the coming of the giant with the two youths. And the earl was anxious both to protect his castle, and to release his two sons. Then Owain put on his armor, and went forth to encounter the giant. And the lion followed him. And, when the giant saw that Owain was armed, he rushed towards him and attacked him. And the lion fought with the giant much more fiercely than Owain did.
"Truly," said the giant, "I should find no difficulty in fighting with thee, were it not for the animal that is with thee."
Upon that, Owain took the lion back to the castle and shut the gate upon him; and then he returned to fight the giant as before. And the lion roared very loud, for he heard that it went hard with Owain. And he climbed up till he reached the top of the earl's hall, and thence he got to the top of the castle; and he sprang down from the walls, and went and joined Owain. And the lion gave the giant a stroke with his paw which tore him from his shoulder to his hip, and his heart was laid bare. And the giant fell down dead. Then Owain restored the two youths to their father.
The earl besought Owain to remain with him; and he would not, but set forward towards the meadow where Luned was. And when he came there he saw a great fire kindled, and two youths with beautiful curling auburn hair were leading the maiden to cast her into the fire. And Owain asked them what charge they had against her. And they told him of the compact that was between them, as the maiden had done the night before.
"And," said they, "Owain has failed her: therefore we are taking her to be burnt."
