Much speedily waxed the child in great beauty; when he was seven years old the Abbot did him to go to the school, and he learned so well, that he over-passed all his fellows in subtilty and science. When he was of twelve years, he was a child exceeding goodly; so it might nought avail to seek a goodlier. And whenas the Abbot saw him to be a child so goodly and gentle, he did him to ride abroad with him.

Now so it fell out, that the Abbot had to speak with the Emperor of a wrong which his bailiffs had done to the abbey. The Abbot made him a goodly gift, whereas the abbey and convent were subject unto him, for the Emperor was a Saracen. When the Abbot had given him his goodly gift, the Emperor gave him day for the third day thence, whenas he should be at a castle of his, three leagues from the city of Byzance.

The Abbot abode the day: when he saw the time at point to go to the Emperor, he mounted a-horseback, and his chaplain, and esquire, and his folk; and with him was Coustans, who was so well fashioned that all praised his great beauty, and each one said that he seemed well to be come of high kindred, and that he would come to great good.

So when the Abbot was come before the castle whereas the Emperor should be, he came before him and spake to and greeted him: and the Emperor said to him that he should come into the castle, and he would speak with him of his matter: the Abbot made him obeisance, and said to him: “Sir, a-God’s name!” Then the Abbot called to him Coustans, who was holding of his hat while he spake unto the Emperor; and the Emperor looked on the lad, and saw him so fair and gentle as never before had he seen the like fair person. So he asked of the Abbot what he was; and the Abbot said him that he wotted not, save that he was of his folk, and that he had bred him up from a little child. “And if I had leisure with thee, I would tell thee thereof fine marvels.” “Yea,” said the Emperor; “come ye into the castle, and therein shalt thou say me the sooth.”

The Emperor came into the castle, and the Abbot was ever beside him, as one who had his business to do; and he did it to the best that he might, as he who was subject unto him. The Emperor forgat in nowise the great beauty of the lad, and said unto the Abbot that he should cause him come before him, and the Abbot sent for the lad, who came straightway.

When the child was before the Emperor, he seemed unto him right fair; and he said unto the Abbot, that great damage it was that so fair a lad was Christian. But the Abbot said that it was great joy thereof, whereas he would render unto God a fair soul. When the Emperor heard that, he fell a-laughing, and said to the Abbot that the Christian law was of no account, and that all they were lost who trowed therein. When the Abbot heard him so say, he was sore grieved; but he durst not make answer as he would, so he said much humbly: “Sir, if God please, who can all things, they are not lost; for God will have mercy of his sinners.”

Then the Emperor asked of him whence that fair child was come; and the Abbot said that it was fifteen years gone since he had been found before their gate, on a midden, all of a night-tide. “And our monks heard him a-crying whenas they had but just said matins; and they went to seek the child, and brought him to me; and I looked on the babe, and beheld him much fair, and I said that I would do him to be nourished and baptized. I unwrapped him, for the babe was wrapped up in a cover-point of vermil sendel; and when he was unwrapped, I saw that he had the belly slit from the breast to the navel. Then I sent for leeches and surgeons, and made market with them to heal him for four-score bezants; and thereafter he was baptized, and I gave him to name Coustans, because he costed so much of goods to heal. So was the babe presently made whole: but never sithence might it be that the mark appeared not on his belly.”

When the Emperor heard that, he knew that it was the child whose belly he had slit to draw the heart out of him. So he said to the Abbot that he should give him the lad. And the Abbot said that he would speak thereof to his convent, and that he should have him with their good-will. The Emperor held his peace, and answered never a word. But the Abbot took leave of him, and came to his abbey, and his monks, and told them that the Emperor had craved Coustans of him. “But I answered that I would speak to you if ye will yea-say it. Say, now, what ye would praise of my doing herein.”

“What!” said the wisest of the convent; “by our faith, evil hast thou done, whereas thou gavest him not presently, even as he demanded of thee. We counsel thee send him straightway, lest the Emperor be wrath against us, for speedily may we have scathe of him.”

Thereto was their counsel fast, that Coustans should be sent to the Emperor. So the Abbot commanded the Prior to lead Coustans thereto; and the Prior said: “A-God’s name!”
