'Behold the reward of thy blessed balsam,' said he, as he bade the earl kneel down before her, and made him swear that he would restore all that he had taken from her.
After that he departed, and went into the deserts, and as he was passing through a wood he heard a loud yelling. Pushing aside the bushes he beheld a lion standing on a great mound, and by it a rock. Near the rock was a lion seeking to reach the mound, and each time he moved out darted a serpent from the rock to prevent him. Then Owen unsheathed his sword, and cut off the serpent's head and went on his way, and the lion followed and played about him, as if he had been a greyhound. And much more useful was he than a greyhound, for in the evening he brought large logs in his mouth to kindle a fire, and killed a fat buck for dinner.
Owen made his fire and skinned the buck, and put some of it to roast, and gave the rest to the lion for supper. While he was waiting for the meat to cook he heard a sound of deep sighing close to him, and he said:
'Who are thou?'
'I am Luned,' replied a voice from a cave so hidden by bushes and green hanging plants that Owen had not seen it.
'And what dost thou here?' cried he.
'I am held captive in this cave on account of the knight who married the countess and left her, for the pages spoke ill of him, and because I told them that no man living was his equal they dragged me here and said I should die unless he should come to deliver me by a certain day, and that is no further than the day after to-morrow. His name is Owen the son of Urien, but Ihave none to send to tell him of my danger, or of a surety he would deliver me.'
Owen held his peace, but gave the maiden some of the meat, and bade her be of good cheer. Then, followed by the lion, he set out for a great castle on the other side of the plain, and men came and took his horse and placed it in a manger, and the lion went after and lay down on the straw. Hospitable and kind were all within the castle, but so full of sorrow that it might have been thought death was upon them. At length, when they had eaten and drunk, Owen prayed the earl to tell him the reason of their grief.
'Yesterday,' answered the earl, 'my two sons were seized, while thy were hunting, by a monster who dwells on those mountains yonder, and he vows that he will not let them go unless I give him my daughter to wife.'
'That shall never be,' said Owen; 'but what form hath this monster?'
'In shape he is a man, but in stature he is a giant,' replied the earl, 'and it were better by far that he should slay my sons than that I should give up my daughter.'
Early next morning the dwellers in the castle were awakened by a great clamour, and they found that the giant had arrived with the two young men. Swiftly Owen put on his armour and went forth to meet the giant, and the lion followed at his heels. And when the great beast beheld the hard blows which the giant dealt his master he flew at his throat, and much trouble had the monster in beating him off.
'Truly,' said the giant, 'I should find no difficulty in fighting thee, if it were not for that lion.' When he heard that Owen felt shame that he could not overcome the giant with his own sword, so he took the lion and shut him up in one of the towers of the castle, and returned to the fight. But from the sound of the blows the lion knew that the combat was going ill for Owen, so he climbed up till he reached the top of the tower, where there was a door on to the roof, and from the tower he sprang on to the walls, and from the walls to the ground. Then with a loud roar he leaped upon the giant, who fell dead under the blow of his paw.
Now the gloom of the castle was turned into rejoicing, and the earl begged Owen to stay with him till he could make him a feast, but the knight said he had other work to do, and rode back to the place where he had left Luned, and the lion followed at his heels. When he came there he saw a great fire kindled, and two youths leading out the maiden to cast her upon the pile.
'Stop!' he cried, dashing up to them. 'What charge have you against her?'
'She boasted that no man in the world was equal to Owen,' said they, 'and we shut her in a cave, and agreed that none should deliver her but Owen himself, and that if he did not come by a certain day she should die. And now the time has past and there is no sign of him.'
'In truth he is a good knight, and had he but known that the maid was in peril he would have come to save her,' said Owen; 'but accept me in his stead, I entreat you.'
'We will,' replied they, and the fight began.
The youths fought well and pressed hard on Owen, and when the lion saw that he came to help his master. But the youths made a sign for the fight to stop, and said:
'Chieftain, it was agreed we should give battle to thee alone, and it is harder for us to contend with yonder beast than with thee.'
Then Owen shut up the lion in the cave where the maiden had been in prison, and blocked up the front with stones. But the fight with the giant had sorely tried him, and the youths fought well, and pressed him harder than before. And when the lion saw that he gave a loud roar, and burst through the stones, and sprang upon the youths and slew them. And so Luned was delivered at the last.
Then the maiden rode back with Owen to the lands of the lady of the fountain. And he took the lady with him to Arthur's court, where they lived happily till they died.
