In the centre of the great hall in the castle of Caerleon upon Usk, king Arthur sat on a seat of green rushes, over which was thrown a covering of flame-coloured silk, and a cushion of red satin lay under his elbow. With him were his Owen and Kynon and Kai, while at the far end, close to the window, were Guenevere the queen and her white garments with strange devices of gold.  
‘I am weary,’ said Arthur, ‘and till my food is prepared I would fain sleep. You yourselves can tell each other tales, and Kai will fetch you from the kitchen a flagon of mean and some meat.’
 
And when they had eaten and drunk, Kynon, the oldest among them, began his story.
 
‘I was the only son of my father and mother, and much store they set by me, but I was not content to stay with them at home, for I thought no deed in all the world was too for me. None could hold me back, and after I had won many adventures in my own land, I bade farewell to my parents and set out to see the world. Over mountains, through deserts, across rivers I went, till I reached a fair valley full of trees, with a path running by the side of a stream. I walked along that path all the day, and in the evening I came to a castle in front of which stood two youths clothed in yellow, each grasping an ivory bow, with arrows made of the bones of the whale, and winged with peacock’s feathers. By their sides hung golden with hilts of the bones of the whale.
 
‘Near these young men was a man richly dressed, who turned and went with me towards the castle, where all the were gathered in the hall. In one window I four and twenty damsels, and the least fair of them was fairer than Guenevere at her fairest. Some took my horse, and others unbuckled my , and washed it, with my sword and spear, till it all shone like silver. Then I washed myself and put on a vest and doublet which they brought me, and I and the man that entered with me sat down before a table of silver, and a goodlier feast I never had.
 
‘All this time neither the man nor the damsels had spoken one word, but when our dinner was half over, and my hunger was stilled, the man began to ask who I was. Then I told him my name and my father’s name, and why I came there, for indeed I had grown weary of gaining the mastery over all men at home, and sought if perchance there was one who could gain the mastery over me. And at this the man smiled and answered:
 
‘“If I did not fear to thee too much, I would show thee what thou seekest.” His words made me sorrowful and fearful of myself, which the man perceived, and added, “If thou meanest truly what thou sayest, and desirest earnestly to prove thy valour, and not to boast vainly that none can overcome thee, I have somewhat to show thee. But to-night thou must sleep in the this castle, and in the morning see that thou rise early and follow the road through the valley, until thou reachest a wood. In the wood is a path branching to the right; go along this path until thou comest to a space of grass with a in the middle of it. On the top of the mound stands a black man, larger than any two white men; his eye is in the centre of his forehead and he has only one foot. He carries a club of iron, and two white men could hardly lift it. Around him graze a thousand beasts, all of different kinds, for he is the of that wood, and it is he who will tell thee which way to go in order to find the adventure thou art in quest of.”
 
‘So spake the man, and long did that night seem to me, and before dawn I rose and put on my armour, and mounted my horse and rode on till I reached the space of which he had told me. There was the black man on top of the mound, as he had said, and in truth he was in all ways than I had thought him to be. As for the club, Kai, it would have been a burden for four of our . He waited for me to speak, and I asked him what power he held over the beasts that so close about him.
 
‘“I will show thee, little man,” he answered, and with his club he struck a stag on the head till he loudly. And at his the animals came running, numerous as the stars in the sky, so that scarce was I able to stand among them. Serpents were there also, and dragons, and beasts of strange shapes, with horns in places where never saw I horns before. And the black man only looked at them and bade them go and feed. And they bowed themselves before him, as before their lord.
 
‘“Now, little man, I have answered thy question and showed thee my power,” said he. “Is there anything else thou wouldest know?” Then I inquired of him my way, but he grew angry, and, as I perceived, would fain have hindered me; but at the last, after I had told him who I was, his anger passed from him.
 
‘“Take that path,” said he, “that leads to the head of this grassy , and go up the wood till thou reachest the top. There thou find an open space, and in the midst of it a tall tree. Under the tree is a fountain, and by the fountain a marble , and on the slab a bowl of silver, with a silver chain. Dip the bowl in the fountain, and throw the water on the slab, and thou wilt hear a might of thunder, till heaven and earth seem trembling with the noise. After the thunder will come hail, so fierce that scarcely canst thou endure it and live, for the hailstones are both large and thick. Then the sun will shine again, but every leaf of the tree will by lying on the ground. Next a flight of birds will come and alight on the tree, and never didst thou hear a strain so sweet as that which they will sing. And at the moment in which their song sounds sweetest thou wilt hear a murmuring and complaining coming towards thee along the valley, and thou wilt see a in black bestriding a black horse, bearing a lance with a black pennon, and he will spur his steed so as to fight thee. If thou turnest to flee, he will overtake thee. And if thou abidest were thou art, he will unhorse thee. And if thou dost not find trouble in that adventure, thou needest not to seek it during the rest of thy life.”
 
‘So I bade the black man farewell, and took my way to the top of the wood, and there I found everything just as I had been told. I went up to the tree beneath which stood the fountain, and filling the silver bowl with water, emptied it on the marble slab. Thereupon the thunder came, louder by far than I had expected to hear it, and after the thunder came the shower, but heavier by far than I had expected to feel it, for, of a truth I tell thee, Kai, not one of those hailstones would be stopped by skin or by flesh till it had reached the bone. I turned my horse’s flank towards the shower, and, bending over his neck, held my shield so that it might cover his head and my own. When the hail had passed, I looked on the tree and not a single leaf was left on it, and the sky was blue and the sun shining, while on the branches were perched birds of very kind, who sang a song sweeter than any that has come to my ears, either before or since.
 
‘Thus, Kai, I stood listening to the birds, when lo, a murmuring voice approached me, saying:
 
‘“O knight, what has brought thee hither? What evil have I done to thee, that thou shouldest do so much to me, for in all my lands neither man nor beast that met that shower has escaped alive.” Then from the valley appeared the knight on the black horse, grasping the lance with the black pennon. Straightway we charged each other, and though I fought my best, he soon overcame me, and I was thrown to the ground, while the knight seized the of my horse, and rode away with it, leaving me where I was, without even me of my armour.
 
‘Sadly did I go down the hill again, and when I reached the glade where the black man was, I confess to thee, Kai, it was a that I did not melt into a liquid pool, so great was my shame. That night I slept at the castle where I had been before, and I was bathed and feasted, and none asked me how I had fared. The next morning when I arose I found a bay horse saddled for me, and, girdling on my armour, I returned to my own court. The horse is still in the stable, and I would not part with it for any in Britain.
 
‘But of a truth, Kai, no man ever confessed an adventure so much to his own , and strange indeed it seems that none other man have I ever met that knew of the black man, and the knight and the shower.’
 
‘Would it not be well,’ said Owen, ‘to go and discover the place?’
 
‘By the hand of my friend,’ answered Kai, ‘often dost thou utter that with thy tongue which thou wouldest not make good with thy deeds.’
 
‘In truth,’ said Guenevere the queen, who had listened to the tale, ‘thou wert better hanged, Kai, than use such speech towards a man like Owen.’
 
‘I meant nothing, lady,’ replied Kai; ‘thy praise of Owen is not greater than mine.’ And as he Arthur awoke, and asked if he had not slept for a little.
 
‘Yes, lord,’ answered Owen, ‘certainly thou hast slept.’
 
‘Is it time for us to go to meat?’
 
‘It is, lord,’ answered Owen.
 
Then the horn for washing themselves was sounded, and after that the king and his household sat down to eat. And when they had finished, Owen left them, and made ready his horse and his arms.
 
With the first rays of the sun he set , and travelled through deserts and over mountains and across rivers, and all befell him which had befallen Kynon, till he stood under the leafless tree listening to the song of the birds. Then he heard the voice, and turning to look found the knight to meet him. Fiercely they fought till their lances were broken, and then they drew their swords, and a blow from Owen cut through the knight’s helmet, and pierced his .
 
Feeling himself wounded unto death the knight fled, and Owen pursued him till they came to a splendid castle. Here the knight dashed across the bridge that spanned the moat, and entered the gate, but as soon as he was safe inside, the drawbridge was pulled up and caught Owen’s horse in the middle, so that half of him was inside and half out, and Owen could not dismount and knew not what to do.
 
While he was in this sore a little door in the castle gate opened, and he could see a street facing him, with tall houses. Then a with curling hair of gold looked through the little door and bade Owen open the gate.
 
‘By my troth!’ cried Owen, ‘I can no more open it from here than thou art able to set me free.’
 
‘Well,’ said she, ‘I will do my best to release thee if thou wilt do as I tell thee. Take this ring and put it on with the stone inside thy hand, and close thy fingers tight, for as long as thou dost it, it will conceal thee. When the men inside have held counsel together, they will come to fetch thee to thy death, and they will be much grieved not to find thee. I will stand on the horse block yonder and thou canst see me though I cannot see thee. Therefore draw near and place thy hand on my shoulder and follow me wheresoever I go.’
 
Upon that she went away from Owen, and when the men came out from the castle to seek him and did not find him they were sorely grieved, and they returned to the castle.
 
Then Owen went to the maiden and placed his hand on her shoulder, and she guided him to a large room, painted all over with rich colours, and with images of gold. Here she gave him meat and drink, and water to wash with and garments to wear, and he lay down upon a soft bed, with and fur to cover him, and slept gladly.
 
In the middle of the night he woke hearing a great outcry, and he jumped up and clothed himself and went into the hall, where the maiden was .
 
‘What is it?’ he asked, and she answered that the knight who owned the castle was dead, and they were bearing his body to the church. Never had Owen beheld such vast crowds, and following the dead knight was the most beautiful lady in the world, whose cry was louder than the shout of the men, or the braying of the . And Owen looked on her and loved her.
 
‘Who is she?’ he asked the damsel. ‘That is my mistress, the countess of the fountain, and the wife of him whom thou didst yesterday.’
 
‘Verily,’ said Owen, ‘she is the woman that I love best.’
 
‘She shall also love thee not a little,’ said the maiden.
 
Then she left Owen, and after a while went into the of her mistress, and spoke to her, but the countess answered her nothing.
 
‘What aileth thee, mistress?’ inquired the maiden.
 
‘Why hast thou kept far from me in my grief, Luned?’ answered the countess, and in her turn the damsel asked:
 
‘Is it well for thee to mourn so bitterly for the dead, or for anything that is gone from thee?’
 
‘There is no man in the world equal to him,’ replied the countess, her cheeks growing red with anger. ‘I would fain thee for such words.’
 
‘Be not angry, lady,’ said Luned, ‘but listen to my counsel. Thou knowest well that alone thou canst not preserve thy lands, therefore seek some one to help thee.’
 
‘And how can I do that?’ asked the countess.
 
‘I will tell thee,’ answered Luned. ‘Unless thou canst defend the fountain all will be lost, and none can defend the fountain except a knight of Arthur’s court. There will I go to seek him, and betide me if I return without a that can guard the fountain, as well as he who kept it before.’
 
‘Go then,’ said the countess, ‘and make proof of that which thou hast promised.’
 
So Luned set out, riding on a white palfrey, on of journeying to King Arthur’s court, but instead of doing that she hid herself for as many days as it would have taken her to go and come, and then she left her hiding-place, and went into the countess.
 
‘What news from the court?’ asked her mistress, when she had given Luned a warm greeting.
 
‘The best of news,’ answered the maiden, ‘for I have gained the object of my mission. When wilt thou that I present to thee the knight who has returned with me?’
 
‘To-morrow at midday,’ said the countess, ‘and I will cause all the people in the town to come together.’
 
Therefore the next day at noon Owen put on his coat of mail, and over it he wore a splendid , while on his feet were leather shoes fastened with clasps of gold. And he followed Luned to the chamber of her mistre............
