'Sirs, I thank you for your courtesy. Go forward swiftly, for I saw such a one as ye go by here but two hours ago, and he flashed in the sun as he rode swiftly. And now I will be as one of you.'

Perceval went swiftly back to his mother's house and found her among her women.

'Mother,' he said, 'I have seen a great and wonderful sight on the great road across the moor.'

'Ah, my dear son, what was that?' she asked.

'They were three honourable knights,' he said. 'And, mother, I will be a knight also.'

With a great shriek his mother swooned away, and the women turned him from the room and said he had slain his mother.

Much grieved was Perceval that he had hurt his mother, and so, taking his store of pointed sticks, he went off into the forest, and strayed there a long time, torn between his love for his mother, and the strange restlessness which the sight of the three warriors had caused in him.

As he wandered, troubled, his quick ear caught the clang of metal, though he knew not what it was. And swiftly he ran towards the sound a long way, until he came into a clearing, and found two knights on horseback doing mighty battle. One bore a red shield and the other a green one.

He looked eagerly at this strange sight, and the blood sang in his veins. And then he saw that the green knight was of slighter frame than the other, and was weakening before the strokes of the red knight.

Full of anger at the sight, Perceval launched one of his hard-wood javelins at the red knight. With such force did it go, and so true was the aim, that it pierced the coif of the knight, and entered between the neck and the head, and the red knight swayed and then clattered to the ground, dead.
