'The blessing of God is upon thee, young White Knight,' said he, 'and now is my watch and ward all ended, and with these my faithful companions may I go.'
'Tell me, sir,' said Perceval, 'what means this?'
'I am Marius,' said the king, 'and I was that Roman soldier who took pity of the gentle Saviour dying in His agony upon the rood. And I helped to take Him from the cross. For my pity did God, whom till then I had not known, deal with me in marvellous wise. And this shield was mine, and a holy hermit in a desert of Syria did bless it, and prophesy concerning it and me. I came to this land of Britain when it was full of evil men, warring fiercely together, and all in heathen darkness. I preached the Word of Christ, I and my fellows that came with me, until the heathens rose up and would slay me. And by that time I was wearied and very old, and wished to die. Yet I sorrowed, wondering whether God would do naught to rescue these people from this slavery to the old evil law. Then a man of God came to me at night, a man of marvel, and he caused this castle to be builded in this ancient wood, and he put my shield upon the post, and bade me and my dear friends sleep. 'For,' said he, 'thou hast earned thy sleep, and others shall carry on thy work and reveal the mercy of God and his Christ to these poor heathens, and they shall turn to God wholly. And no evil shall be able to break in upon thy repose. But when, in the distant future, men's hearts are turning to evil again, one that is of the three white knights shall come and take this shield, to ward him in the great battle against evil, and then thou and all that are with thee shall have the restfulness of death thou hast merited. Go then, thou good knight,' went on King Marius, 'fight the good fight against that thing of evil whom the good man spoke of, and may my shield encompass thee and ever guard thee.'
Perceval took the shield and left his own. Turning, he rode back between lines of silent forms bent in prayer. He went forth into the forest some little way, and heard from the castle the singing of a joyful hymn. And, looking back, he saw that the castle had vanished. But still above him and about him was the sound of singing, of a sweetness indescribable, as if they sang who had gained all that they desired.
Then Perceval rode forward till it was night; but never could he get sight of castle or knight's hold or hermit's cell where he could be houselled for the night. So he abode in the forest that night, and when he had prayed he slept beside his good horse until it was day.
Just before the dawn he awoke to the sound of a great rushing wind all about him. Yet marvel it was to see that the trees in that hoar wood did not wave their branches, but all were still.
Then he was aware of a sweet savour which surrounded him, and anon a gentle voice spoke out of the darkness.
'Fair White Knight,' said the voice, 'it is ordained of thee that thou goest to the lands of the King Pellam in the north, where an evil power seeks to turn men from the New Law which Christ brought, and to make them cleave to the Old Law with its cruelty and evil tortures. And there at the Castle of the Circlet thou shalt fight a battle for the Saviour of the world. And whether thou shalt win through all, none know as yet. But in thy purity, thy humility, is thy strength. Fare thee well!'
Much moved at these words, Perceval knelt and prayed, and then, as the dawn filtered through the trees, he mounted his horse and began his long journey to the north.
On the seventh day he crossed a plain, and saw far in the north where the smoke as of fires rose into the clouds, and here and there he saw the fierce red gleam of flames. And he passed through a ford, and then he entered a land all black and desolate, with the bodies of the dead beside the way, unburied, and the houses all broken or burned. In other places the grass and weeds grew over the hearths of desolated homes, and wild beasts made their lairs where homely folk seemed lately to have lived their simple happy lives.
