There was at that time a certain monk, learned in heavenly things, graced in word and deed, a model follower of every monastic rule. Whence he sprang, and what his race, I cannot say, but he dwelt in a waste howling wilderness in the land of Senaar, and had been perfected through the grace of the priesthood. Barlaam was this elder's name. He, learning by divine revelation the state of the king's son, left the desert and returned to the world. Changing his habit, he put on lay attire, and, embarking on ship board, arrived at the seat of the empire of the Indians. Disguised as a merchant man, he entered the city, where was the palace of the king's son. There he tarried many days, and enquired diligently concerning the prince's affairs, and those that had access to him. Learning that the tutor, of whom we have spoken, was the prince's most familiar friend, he privily approached him, saying, "I would have thee understand, my lord, that I am a merchant man, come from a far country; and I possess a precious gem, the like of which was never yet found, and hitherto I have shewed it to no man. But now I reveal the secret to thee, seeing thee to be wise and prudent, that thou mayest bring me before the king's son, and I will present it to him. Beyond compare, it surpasseth all beautiful things; for on the blind in heart it hath virtue to bestow the light of wisdom, to open the ears of the deaf, to give speech to the dumb and strength to the ailing. It maketh the foolish wise and driveth away devils, and without stint furnisheth its possessor with everything that is lovely and desirable." The tutor said, "Though, to all seeming, thou art a man of staid and steadfast judgment, yet thy words prove thee to be boastful beyond measure. Time would fail me to tell thee the full tale of the costly and precious gems and pearls that I have seen. But gems, with such power as thou tellest of, I never saw nor heard of yet. Nevertheless shew me the stone; and if it be as thou affirmest, I immediately bear it to the king's son, from whom thou shalt receive most high honours and rewards. But, before I be assured by the certain witness of mine own eyes, Imay not carry to my lord and master so swollen a tale about so doubtful a thing." Quoth Barlaam, "Well hast thou said that thou hast never seen or heard of such powers and virtues; for my speech to thee is on no ordinary matter, but on a wondrous and a great. But, as thou desiredst to behold it, listen to my words.
"This exceeding precious gem, amongst these its powers and virtues, possesseth this property besides. It cannot be seen out of hand, save by one whose eyesight is strong and sound, and his body pure and thoroughly undefiled. If any man, lacking in these two good qualities, do rashly gaze upon this precious stone, he shall, I suppose lose even the eyesight that he hath, and his wits as well. Now I, that am initiated in the physician's art, observe that thine eyes are not healthy, and I fear lest I may cause thee to lose even the eyesight that thou hast. But of the king's son, I have heard that he leadeth a sober life, and that his eyes are young and fair, and healthy. Wherefore to him Imake bold to display this treasure. Be not thou then negligent herein, nor rob thy master of so wondrous a boon." The other answered, "If this be so, in no wise show me the gem; for my life hath been polluted by many sins, and also, as thou sayest, I am not possest of good eyesight. But I am won by thy words, and will not hesitate to make known these things unto my lord the prince." So saying, he went in, and, word by word, reported everything to the king's son. He, hearing his tutor's words, felt a strange joy and spiritual gladness breathing into his heart, and, like one inspired, bade bring in the man forthwith.
