"For whether I marry the maid or no, I will call you by that word for the love of your wisdom; and even now I will ride forth and search the world for the stone of touch." So he said farewell, and rode into the world.
"I think I will go, too," said the younger son, "if I can have your leave. For my heart goes out to the maid."
"You will ride home with me," said his father.
So they rode home, and when they came to the dun, the King had his son into his treasury. "Here," said he, "is the touchstone which shows truth; for there is no truth but plain truth; and if you will look in this, you will see yourself as you are."
And the younger son looked in it, and saw his face as it were the face of a beardless youth, and he was well enough pleased; for the thing was a piece of a mirror.
"Here is no such great thing to make a work about," said he; "but if it will get me the maid I shall never complain. But what a fool is my brother to ride into the world, and the thing all the while at home!"
So they rode back to the other dun, and showed the mirror to the King that was a priest; and when he had looked in it, and seen himself like a King, and his house like a King's house, and all things like themselves, he cried out and blessed God. "For now I know," said he, "there is no truth but the plain truth; and I am a King indeed, although my heart misgave me." And he pulled down his temple, and built a new one; and then the younger son was married to the maid.
In the meantime the elder son rode into the world to find the touchstone of the trial of truth; and whenever he came to a place of habitation, he would ask the men if they had heard of it. And in every place the men answered: "Not only have we heard of it, but we alone, of all men, possess the thing itself, and it hangs in the side of our chimney to this day". Then would the elder son be glad, and beg for a sight of it. And sometimes it would be a piece of mirror, that showed the seeming of things; and then he would say, "This can never be, for there should be more than seeming". And sometimes it would be a lump of coal, which showed nothing; and then he would say, "This can never be, for at least there is the seeming". And sometimes it would be a touchstone indeed, beautiful in hue, adorned with polishing, the light inhabiting its sides; and when he found this, he would beg the thing, and the persons of that place would give it him, for all men were very generous of that gift; so that at the last he had his wallet full of them, and they chinked together when he rode; and when he halted by the side of the way he would take them out and try them, till his head turned like the sails upon a windmill.
"A murrain upon this business!" said the elder son, "for I perceive no end to it. Here I have the red, and here the blue and the green; and to me they seem all excellent, and yet shame each other. A murrain on the trade! If it were not for the King that is a priest and whom I have called my father, and if it were not for the fair maid of the dun that makes my mouth to sing and my heart enlarge, I would even tumble them all into the salt sea, and go home and be a King like other folk."
But he was like the hunter that has seen a stag upon a mountain, so that the night may fall, and the fire be kindled, and the lights shine in his house; but desire of that stag is single in his bosom.
Now after many years the elder son came upon the sides of the salt sea; and it was night, and a savage place, and the clamour of the sea was loud. There he was aware of a house, and a man that sat there by the light of a candle, for he had no fire. Now the elder son came in to him, and the man gave him water to drink, for he had no bread; and wagged his head when he was spoken to, for he had no words.
"Have you the touchstone of truth?" asked the elder son and when the man had wagged his head, "I might have known that," cried the elder son. "I have here a wallet full of them!" And with that he laughed, although his heart was weary.
