Perceval went to the stable and took a bony, piebald horse, which seemed the strongest, and he pressed a pallet of straw into the semblance of a saddle, and with pieces of leather and wood he imitated the trappings he had seen on the horses of the knights.
Then, after taking leave of his mother, he rode forth, sad at first for leaving her in sorrow and tears, but afterwards glad that now he was going into the world to become a knight. And for armour he had a rough jerkin, old and moth-eaten, and for arms he had a handful of sharp-pointed sticks of hard wood.
He journeyed southwards two days and two nights along the great straight road, which went through the deep dark forests, over desert places and over the high mountains. And all that time he ate nothing but wild berries, for he had not thought to bring food with him.
While he was yet but a little way from the court of King Arthur, a stranger knight, tall and big, in black armour, had ridden into the hall where sat Gwenevere the queen, with a few of the younger knights and her women. The page of the chamber was serving the queen with wine in a golden goblet richly wrought, which Lancelot had taken from a knight whom he had lately slain.
The stranger knight had alighted before the chair of Gwenevere, and all had seen that full of rage and pride was his look. And he caught sight of the goblet in the hand of Gwenevere, and he snatched it from her, spilling the wine over her dress and dashing it even into her face.
'Now am I well lighted here,' he said, 'for this is the very goblet which thy robber knight Sir Lancelot reaved from my brother, Sir Wilder. And if any of you knights here desire to wrest this goblet from me, or to avenge the insult I have done your queen, let him come to the meadow beside the ford, and I will slay him, ay, if it be that traitor Sir Lancelot himself.'
All the young knights hung their heads as he mounted his horse and insolently rode out of the hall; for it seemed to them that no one would have done so daring an outrage unless, like Sir Garlon whom Balin slew, he fought with evil magic, so that the strength and prowess of the mightiest knight would be put to naught.
Then Perceval entered the hall, and at sight of him upon his rough piebald horse, with its uncouth trappings, and the old and mouldy jerkin upon the youth, the knights and others broke forth in excessive laughter, as much at the sight as to cover their discomfiture and fear of the knight who had just gone.
But Perceval took no note of their laughter, but rode up the hall to where Sir Kay the seneschal stood, wrathful at the outrage on the queen which he had not dared to avenge instantly. And Perceval looked about and saw a knight more richly dressed than the others, and, turning to Kay, he said:
'Tell me, tall man, is that King Arthur yonder?'
