"No," said Lancelot, "it is not for me. Remember, my lord, all the wonderful things that Merlin told long ago. The best knight of the world is not among us yet, but I believe that he is coming soon. Let us all go back to the hall, my lord, and keep our feast and wait for him."
And back they went to the hall, and they were scarcely in their places when there came another wonder. An old man came into the hall, leading a young man by the hand. They saw that he was an old man only by his figure and by his step and by the end of a white beard which they could see. For he wore a long, white robe, and a hood hung low down over his face, so that they could not see it. The young man was dressed all in flame-colored armor, and he had no shield or sword, but an empty scabbard hung by his side. They came and stood close to the throne and closer to the Siege Perilous. Bors sat near them, and it seemed to him that he knew, just as it had seemed to him once before, long ago, at the Castle of Carbonek, that this old man was Joseph of Arimathæa, who would have died hundreds of years ago, but that the power of the Holy Grail kept him alive. And he knew, too, that the young man was the beautiful child with the deep eyes and the bright, sweet face and the hair like gold, whom he had seen at the Castle of Carbonek. Percivale sat next to Bors, and it seemed to him too that he knew the old man, though how he could not tell. Next to Bors on the other side was Lancelot, and what he knew was that the young man was the one whom he had made a knight that morning at the abbey.
"King Arthur," said the old man, "I have brought you a new knight, Sir Galahad. You have waited for him long, for you were told of him before he was born, and his place at your Round Table was waiting for him before you yourself were born."
"He is welcome here," said the King, "and you are welcome too." But almost before he had spoken the old man was gone from the hall and the young knight in the flame-colored armor stood before him alone. Yes, there at last he stood, Galahad, whose name had been spoken with wonder or with hope or with doubt so many times. Only the best knight of the world, Merlin had said, should sit in the Siege Perilous, and the best knight of the world should be Galahad. How many times Arthur had looked at that seat and wondered why his best knight, Lancelot, could not sit there, and what the knight could be like who should be better than Lancelot. And now here he stood—Galahad.
But there was something else for the best knight of the world to do. The knights who filled the hall were not thinking then of the Siege Perilous. They were thinking of the stone floating on the river, and the sword sticking in it. The King saw them whispering together and pointing that way and he said to the young man: "If you are indeed that Galahad whom we have waited for so long, you are more welcome than any other who has come here since Lancelot, my best knight till now, the son of my old friend King Ban. It you are that true Galahad who was promised, then you will be the best of all my knights—better than Lancelot. Will you come and prove to us whether you are so?"
Then the King took the young man's hand and led him down to the river and all the rest followed them to see. And the King said: "Try if you can draw that sword, for none of my other knights can draw it."
"See, my lord," said the young man, "I have brought no sword, only this empty scabbard, for I knew that I should find my sword here." And he took hold of the sword that stuck in the stone and drew it out and put it in his scabbard.
There was no doubt of it now; the knight whom they had waited for had come. Yet the King's face was sad as he led the way back to the hall, for it seemed to him that now there could be little to wait for and the days of the Round Table would not be many more. But other thoughts came to him a moment later, when the new knight knelt before him to take the oath that would make him a knight of the Round Table. For then, just for an instant, it seemed to him that the time had gone back to the beginning of his reign. There was a look in the young man's eyes that brought back the day when Lancelot had knelt before him like this and had sworn this oath and when he had believed that Lancelot would surely be the one perfect knight. Yes, it was the same clear light that he had seen for an instant that day in Lancelot's eyes, the glow of something great and wonderful, he knew not what. But there was more in the face of this new knight. There was something which told Arthur that, though he swore that in all things he would be true and loyal to God and to the King, yet, without the oath, he could never have a thought that would not be true and loyal.
And the King scarcely knew whether it was great joy or great sorrow that made him almost tremble before this boy. And when he took his hand again they all saw that his face was white as he turned toward the seat that was next the throne. And there at last in that Siege Perilous were the letters, more of fire than of gold, as they seemed: "This is the seat of Galahad."
Those who could see whispered to those who could not and the word ran down the hall and then in an instant everyone was still. After all these years of waiting, after the wonders and the prophecies, would any one, even Galahad, dare to sit in that seat? They had feared that seat and had seen it empty so long that they could not believe it, and they all stood up in their places and strained their eyes and held their breaths in wonder and dread. And of all who were there Galahad alone had no fear and no dread. Only for an instant he stood there, with the eyes of all the rest upon him and his own upon the King's, and then he sat in the Siege Perilous.
