"Fair nephew, had they been chaste as are you, well might they have entered on account of their good knighthood. For were they not wanton, the two best knights in the world are they.

"Fair nephew, in the time of your knighthood have you much advanced the Law of the Saviour, for you have destroyed the falsest believe in the world, and this was of them that believed on the bull of copper and the devil that was therein. If this folk had remained, and had failed of you, never would it have been destroyed until the end of the world. Wherefore marvel not that you have travail in serving God, but endure it willingly, for never had worshipful man honour without pains. But now behoveth you achieve another matter. All they of the land of King Fisherman your uncle have abandoned the New Law, and returned to that which God hath forbidden. But the most part do so rather perforce and for fear of the King that hath seized the land, who is my brother and your uncle, than on account of aught else. Wherefore behoveth you set counsel therein, for this thing may not be achieved by any earthly man save by you only. For the castle and land should be yours of right, and sore mischief is it when one that cometh of lineage so high and so holy is traitor to God, and disloyal to the world.

"Fair nephew," saith the good man, "The castle hath been much strengthened, for there are now nine bridges newly made, and at each bridge are there three knights tall and strong and hardy, whereof hath he much defence, and your uncle is there within that keepeth the castle. But never sithence, none of the knights of King Fisherman nor of his priests have there appeared, nor knoweth any what hath befallen them. The chapel wherein the most Holy Graal appeared is all emptied of its sacred hallows; the hermits that are by the forest are fain of your coming, for never see they there a knight pass by that believeth in God. And so you shall have achieved this enterprise, it is a thing whereof shall God be well pleased."

"Fair uncle," saith Perceval, "Thither will I go, sith that you commend it to me, for no reason is it that he should have the castle that hath entered thereinto. Of better right ought my mother to have it, that was the next-born to King Fisherman, of whose death am I right sorrowful."
"Fair nephew, you are right! for on your account fell he into languishment, and, had you then gone again, so say many, then would he have been whole, but how this might have been I know not of a certainty. But methinketh our Lord God willed his languishment and death, for had it been His will, you would have made the demand, but He willed otherwise, wherefore ought we to give thanks and praise Him whatsoever He doth, for He hath foreseen of every man that which shall come to him. I have within here a white mule that is very old. Fair nephew, you will take her with you. She will follow you right willingly, and a banner shall you bear, for the power of God and His virtue shall avail more than your own. Seven-and-twenty knights guard the nine bridges, all chosen and of approved great valour, and none ought now to believe that a single knight may vanquish so many, save the miracle of Our Lord and His virtue shall open a way for him. So I pray and beseech you that you have God always in remembrance and His sweet Mother, and, so at any time you be put to the worse of your knighthood, mount upon the mule and take the banner, and your enemies shall forthwith lose their force, for nought confoundeth any enemy so swiftly as doth the virtue and puissance of God. It is a thing well known that you are the Best Knight of the World, but set not affiance in your strength nor in your knighthood as against so many knights, for against them may you not endure."
XXII.
Perceval hearkeneth unto his uncle's discourse and his chastening, and layeth fast hold on all that he saith, wherewith is he pleased full well, for great affiance hath he in his words.
