And the three bulls which were white save only one that was spotted: the two white betoken Sir Galahad and Sir Percivale, for they be maidens clean and without spot; and the third that had a spot signifieth Sir Bors de Ganis, which trespassed but once in his virginity, but sithen he kept himself so well in chastity that all is forgiven him and his misdeeds. And why those three were tied by the necks, they be three knights in virginity and chastity, and there is no pride smitten in them. And the black bulls which said: Go we hence, they were those which at Pentecost at the high feast took upon them to go in the quest of the Sangreal without confession: they might not enter in the meadow of humility and patience. And therefore they returned into waste countries, that signifieth death, for there shall die many of them: everych of them shall slay other for sin, and they that shall escape shall be so lean that it shall be marvel to see them. And of the three bulls without spot, the one shall come again, and the other two never.

How the hermit expounded their advision.

Then spake Nacien unto Ector: Sooth it is that Launcelot and ye came down off one chair: the chair betokeneth mastership and lordship which ye came down from. But ye two knights, said the hermit, ye go to seek that ye shall never find, that is the Sangreal; for it is the secret thing of our Lord Jesu Christ. What is to mean that Sir Launcelot fell down off his horse: he hath left pride and taken him to humility, for he hath cried mercy loud for his sin, and sore repented him, and our Lord hath clothed him in his clothing which is full of knots, that is the hair that he weareth daily. And the ass that he rode upon is a beast of humility, for God would not ride upon no steed, nor upon no palfrey; so in ensample that an ass betokeneth meekness, that thou sawest Sir Launcelot ride on in thy sleep. And the well whereas the water sank from him when he should have taken thereof, and when he saw he might not have it, he returned thither from whence he came, for the well betokeneth the high grace of God, the more men desire it to take it, the more shall be their desire.
