Then Kynon implored him to make trial of him, and at length the man agreed. "Sleep here to-night," said he, "and on the morning arise early, and take the road upward through the valley till you come to the wood by which you came. A little way within the wood you will find a path branching off to the right. Follow this until you come to a large, sheltered glade, with a mound in the centre. On the top of the mound you will see a black man of great size, larger than two men of this world. He has but one foot, and one eye in the middle of his forehead. In his hand he holds a club which no two men could lift. He is exceedingly ill-favoured to look at, and he is the warden of that wood. And round about him you will see grazing a thousand wild animals. Inquire of him the way out of the glade, and he will point out the road which will lead you to that of which you are in quest."
Next morning Kynon arose very early, and rode away. All came to pass as the Man in Yellow had said, except that the black man was of huger size and his club looked far heavier than Kynon had been led to suppose. When Kynon saw the thousand animals browsing around the mound and the black man sitting on the top of it, he asked what power he held over those creatures.
"I will show thee, little man," said he; and, taking up his club, he struck one of the stags a great blow. The stag brayed loudly, and at the sound all the animals came together, as many as the stars in the sky, so that Kynon scarcely found room to stand. Serpents were there, and dragons, and every kind of beast. Then the black man looked at them, and bade them go feed; and they all bowed their heads, and did homage to him ere they departed.
Then Kynon asked the way out of the glade; and when the man knew his reason he said to him: "Take the path that leads towards the head of the glade, and ascend the woody steeps until you reach the summit; there you will find an open space like a large valley, and in the midst of it a tall tree, with branches greener than the greenest pine-trees.
"Beneath this tree is a fountain, and by the fountain a marble slab, and on the slab a silver bowl attached by a silver chain. Take the bowl, and throw a bowlful of water on the slab, and you shall see what will happen. And if you do not find trouble in that adventure you need not seek it during the rest of your life."
So Kynon did as he had said, and found the fountain, and threw a bowlful of water upon the slab. And immediately there came a mighty peal of thunder, so that the earth shook. With the thunder came a shower of hailstones, so heavy that each one pierced to the bone, and Kynon could only endure it by placing his shield over his own and his horse's head. After that the weather became fair; but when he looked at the tree, behold! there was not a single leaf left upon it. Then a flock of birds came, and alighted on the tree, and never was heard such sweet strains as those they sang; and while he was listening to the birds a murmuring voice rose through the valley, like a gust of wind, which said:
"O knight, what has brought you hither? What evil have I done to you that you should act towards me and my possessions as you have this day? Do you not know that the shower to-day has left alive neither beast nor man that was exposed to it?"
Scarcely had the voice died away when there appeared a knight clad in black velvet, riding a coal-black horse, who made a rush at Kynon then and there. And the onset was so furious, and Kynon so little prepared, that he was overthrown. Then the Black Knight passed the shaft of his lance through the bridle-rein of Kynon's horse, and, without a glance at his fallen adversary, rode off the way he had come. There was nothing left for the fallen knight but to make his way back to the castle. The black man jeered aloud at him as he passed through the glade, and, with much anger and mortification, the knight hurried on to the castle of the Man in Yellow. There he was received with the utmost hospitality; and no one alluded to his adventure, nor did he mention it to any. On the next day he found, ready saddled, a dark bay horse, with nostrils as red as scarlet, and, mounted on this, he returned to Arthur's Court.
II. The Tale of Owain
When Kynon had related at Arthur's Court the story of his adventure with the Black Knight, one of his companions, Owain by name, said: "Is it not befitting that one of us go and discover this place?"
