How Sir Galahad Departed, and How He Was Commanded to Go to the Castle of Maidens to Destroy the Wicked Custom
NOW will I depart, said Galahad, for I have much on hand, for many good knights be full busy about it, and this knight and I were in the same quest of the Sangreal. Sir, said the good man, for his sin he was thus wounded; and I marvel, said the good man, how ye durst take upon you so rich a thing as the high order of knighthood without clene confession, and that was the cause ye were bitterly wounded. For the way on the right hand betokeneth the highway of our Lord Jesus Christ, and the way of a good true good liver. And the other way betokeneth the way of sinners and of misbelievers. And when the devil saw your pride and presumption, for to take you in the quest of the Sangreal, that made you to be overthrown, for it may not be achieved but by virtuous living. Also, the writing on the cross was a signification of heavenly deeds, and of knightly deeds in Gods works, and no knightly deeds in worldly works. And pride is head of all deadly sins, that caused this knight to depart from Galahad. And where thou tookest the crown of gold thou sinnest in covetise and in theft: all this were no knightly deeds. And this Galahad, the holy knight, the which fought with the two knights, the two knights signify the two deadly sins which were wholly in this knight Melias; and they might not withstand you, for ye are without deadly sin. Now departed Galahad from thence, and be-taught them all unto God. Sir Melias said: My lord Galahad, as soon as I may ride I shall seek you. God send you health, said Galahad, and so took his horse and departed, and rode many journeys forward and backward, as adventure would lead him. And at the last it happened him to depart from a place or a castle the which was named Abblasoure; and he had heard no mass, the which he was wont ever to hear or ever he departed out of any castle or place, and kept that for a custom. Then Sir Galahad came unto a mountain where he found an old chapel, and found there nobody, for all, all was desolate; and there he kneeled tofore the altar, and besought God of wholesome counsel. So as he prayed he heard a voice that said: Go thou now, thou adventurous knight, to the Castle of Maidens, and there do thou away the wicked customs.
