‘Though thou get all these things yet there is that which thou wilt not get. Throughout the world there is none that can hunt with this dog save Mabon the son of Modron. He was taken from his mother when three nights old, and it is not know where he now is, nor whether he is living or dead, and though thou find him yet the boar will never be slain save only with the sword of Gwrnach the giant, and if thou obtain it not neither shalt thou obtain my daughter.’ ‘Horses shall I have, and knights from my lord Arthur. And I shall gain thy daughter, and thou shalt lose thy life.’ The speech of Kilweh the son of Kilydd with Yspaddaden Penkawr was ended. Then Arthur’s men set forth, and Kilweh with them, and journeyed till they reached the largest castle in the world, and a black man came out to meet them. ‘Whence comest thou, O man?’ asked they, ‘and whose is that castle?’ ‘That is the castle of Gwrnach the giant, as all the world knows,’ answered the man, ‘but no guest ever returned thence alive, and none may enter the gate except a craftsman, who brings his trade.’ But little did Arthur’s men heed his warning, and they went straight to the gate. ‘Open!’ cried Gwrhyr. ‘I will not open,’ replied the porter. ‘And wherefore?’ asked Kai. ‘The knife is in the meat, and the drink is in the horn, and there is revelry in the hall of Gwrnach the giant, and save for a craftsman who brings his trade the gate will not be opened to-night.’ ‘Verily, then, I may enter,’ said Kai, ‘for there is no better burnisher of swords than I.’ ‘This will I tell Gwrnach the giant, and I will bring thee his answer.’ ‘Bid the man come before me,’ cried Gwrnach, when the porter had told his tale, ‘for my sword stands much in need of polishing,’ so Kai passed in and saluted Gwrnach the giant. ‘Is it true what I hear of thee, that thou canst burnish swords?’ ‘It is true,’ answered Kai. Then was the sword of Gwrnach brought to him. ‘Shall it be burnished white or blue?’ said Kai, taking a whetstone from under his arm. ‘As thou wilt,’ answered the giant, and speedily did Kai polish half the sword. The giant marvelled at his skill, and said: ‘It is a wonder that such a man as thou shouldst be without a companion.’ ‘I have a companion, noble sir, but he has no skill in this art.’ ‘What is his name?’ asked the giant. ‘Let the porter go forth, and I will tell him how he may know him. The head of his lance will leave its shaft, and draw blood from the wind, and descend upon its shaft again.’ So the porter opened the gate and Bedwyr entered. Now there was much talk amongst those who remained without when the gate closed upon Bedwyr, and Goreu, son of Custennin, prevailed with the porter, and he and his companions got in also and hid themselves. By this time the whole of the sword was polished, and Kai gave it into the hand of Gwrnach the giant, who felt it and said: ‘Thy work is good; I am content.’ Then said Kai:
