'Fair sir,' she said, 'my maiden hath told me who thou art, and I sorrow that one so noble as thou seemest shall essay to overcome the fiend knight of the Dragon. Yet if thou shouldst prevail, all men in this tortured land will bless thee, and I not the least. For daily doth the evil knight slay my poor knights, and cometh and casteth their blackened and burned bodies before my hall. And many of my poor folk hath he slain or enslaved, and others hath he caused to follow his evil worship, and many of my rich and fair lands hath he wrested from me.'

'Therefore, fair lady,' said Perceval, 'I would seek him without delay, for to essay the force of my body upon him, by the grace of God.'

'And shouldst thou conquer,' said the lady, 'with the fiend's death the hallowed relics which King Pellam guarded shall return to bless this land. Now, therefore, go ye towards the Burnt Land beyond the brook, for that is where is the lair of the fiend that doth oppress us.'

Perceval went forward across the plain to a brook, and having forded the water he came to a wide hollow where the ground was all baked and burned, and the trees were charred and black. Here and there lay pieces of armour, red and rusted, as if they had been in a fierce fire; and in one place was the body of a knight freshly slain, and he was charred and black.

Then, as Perceval looked about him, he saw the dark hole of a cave in a bank beside the hollow, and suddenly therefrom issued a burst of horrible fire and smoke, and with a cry as of a fiend a black knight suddenly appeared before him on a great horse, whose eyes flashed as with fire and whose nostrils jetted hot vapours.

'Ha! thou Christian!' cried the knight in a horrible voice, 'what dost thou here? Wouldst thou have thy pretty white armour charred and blackened and thyself killed by my dragon's power?'

Then Perceval saw how the boss of the Black Knight's shield was the head of a dragon, its forked tongue writhing, its teeth gnashing, and its eyes so red and fiendish that no mortal, unless by God's aid, could look on it and live. From its mouth came a blinding flash as of lightning and beat at Perceval, but he held up his shield of the Throbbing Heart, and with angry shrieks the Black Knight perceived that the lightning could not touch the shield.

Then from his side the evil knight tore his sword, and it flamed red as if it was heated in a fierce furnace, and thrusting forward he came and beat at Perceval. But the White Knight warded off the blows with his shield, which the flaming sword had no power to harm.

Then did the Black Knight marvel greatly, for never had a knight, however skilled, withstood him, for either the lightning of the dragon shield had burnt him, or the stroke of his flaming sword had slain him swiftly. And by this he knew that this knight was Perceval.

'Thou knowest not who it is thou fightest,' said the Black Knight, with a scornful laugh. 'Thou must put forth more than the skill thou didst learn of the witches of Glaive if thou wouldst overcome me. For know ye, that I am a fosterling of Domna the witch, and she taught me more than ever she taught you. Now prepare ye to die.'
