Now it chanced that the Emperor Muselin fared forth one night, he and a certain lord of his together, and went their ways about this city of Constantinople, and the moon shone very clear. They heard a Christian woman, travailing of child, cry aloud as they passed before her house; but the husband of this dame was set in the terrace upon his roof, and now he prayed God to deliver her from her peril, and again he prayed that she might not be delivered. When the Emperor had listened to his words for a long time, he said to the knight-- "Have you heard this caitif who prays now that his wife may not be delivered of her child, and again that she may be delivered? Surely he is viler than any thief, for every man should show pity to woman, and the greater pity to her in pain with child. But may Mahound and Termagaunt aid me never if I hang him not by the neck, so he give me not fair reason for this deed. Let us now go to him." So they went, and the Emperor spake him thus, "Caitif, tell me truly why thou prayest thy God in this fashion, now that He should deliver thy wife in her labour, and again that she should not be delivered; this must I know!" "Sire," answered he, "I will tell you readily. Truly I am a clerk, and know much of a science that men call astrology. I have learned, too, the courses of the stars and the planets, and thus I knew well that were my wife delivered in that hour when I prayed God to close her womb, then the child must be for ever lost, and certainly would he be hanged, or drowned, or set within the fire. But when I saw the hour was good, and the case fair, then I prayed God that she might be delivered; and I cried to Him, so that of His mercy He heard my prayer, and now the boy is born to a goodly heritage; blessed be God and praised be His Name." "Now tell me," said the King, "to what fair heritage is this child born?" "Sire," said he, "with all my heart. Know, sire, of a truth that the child born in this place shall have to wife the daughter of the Emperor of this town, she who was born but eight days since, and shall become Emperor and lord of this city, and of the whole world." "Caitif," cried the Emperor, "never can it come to pass as thou sayest." "Sire," answered he, "so shall it be seen, and thus behoveth it to be." "Certes," said the Emperor, "great faith hath he who receives it."
