The physician being on his knees, his eyes tied up, and ready to receive the fatal blow, addressed himself once more to the king: "Sir," said he, "since your majesty will not revoke the sentence of death, I beg, at least, that you would give me leave to return to my house, to give orders about my burial, to bid farewell to my family, to give alms, and to bequeath my books to those who are capable of making good use of them. I have one particularly I would present to your majesty; it is a very precious book, and worthy of being laid up carefully in your treasury." "What is it," demanded the king, "that makes it so valuable?" "Sir," replied the physician, "it possesses many singular and curious properties; of which the chief is, that if your majesty will give yourself the trouble to open it at the sixth leaf, and read the third line of the left page, my head, after being cut off, will answer all the questions you ask it." The king being curious, deferred his death till next day, and sent him home under a strong guard.
The physician, during that time, put his affairs in order; and the report being spread, that an unheard of prodigy was to happen after his death, the viziers, emirs, officers of the guard, and, in a word, the whole court, repaired next day to the hall of audience, that they might be witnesses of it.
The physician Douban was brought in, and advancing to the foot of the throne, with a book in his hand, he called for a basin, and laid upon it the cover in which the book was wrapped; then presenting the book to the king, "Take this," said he, "and after my head is cut off, order that it be put into the basin upon that cover; as soon as it is placed there, the blood will stop; then open the book, and my head will answer your questions. But permit me once more to implore your majesty's clemency; for God's sake grant my request, I protest to you that I am innocent." "Your prayers," answered the king, "are in vain; and were it for nothing but to hear your head speak after your death, it is my will you should die." As he said this, he took the book out of the physician's hand, and ordered the executioner to do his duty.
The head was so dexterously cut off that it fell into the basin, and was no sooner laid upon the cover of the book than the blood stopped; then to the great surprise of the king, and all the spectators, its eyes, and said, "Sir, will your majesty be pleased to open the book?" The king proceeded to do so; but finding that the leaves adhered to each other, that he might turn them with more ease, he put his finger to his mouth, and wetted it with spittle. He did thus till he came to the sixth leaf, and finding no writing on the place where he was desired to look for it, "Physician," said he, "there is nothing written." "Turn over some more leaves," replied the head. The king went on, putting always his finger to his mouth, until the poison with which each leaf was imbued, coming to have its effect, the prince found himself suddenly taken with an extraordinary fit, his eye-sight failed, and he fell down at the foot of the throne in violent convulsions.
When the physician Douban, or rather his head, saw that the poison had taken effect, and that the king had but a few moments to live; "Tyrant," it cried, "now you see how princes are treated, who, abusing their authority, cut off innocent men: God punishes soon or late their injustice and cruelty." Scarcely had the head spoken these words, when the king fell down dead, and the head itself lost what life it had.
As soon as the fisherman had concluded the history of the Greek king and his physician Douban, he made the application to the genie, whom he still kept shut up in the vessel. "If the Grecian king," said he, "had suffered the physician to live, God would have continued his life also; but he rejected his most humble prayers, and the case is the same with thee, O genie! Could I have prevailed with thee to grant me the favour I supplicated, I should now take pity on thee; but since, notwithstanding the extreme obligation thou west under to me, for having set thee at liberty, thou didst persist in thy design to kill me, I am obliged, in my turn, to be equally hard-hearted to thee."
"My good friend fisherman," replied the genie, "I conjure thee once more, not to be guilty of such cruelty; consider, that it is not good to avenge one's self, and that on the other hand, it is commendable to do good for evil; do not treat me as Imama formerly treated Ateca." "And what did Imama to Ateca?" enquired the fisherman. "Ho!" says the genie, "if you have a mind to be informed, open the vessel: do you think that I can be in an humour to relate stories in so strait a prison? I will tell you as many as you please, when you have let me out." "No," said the fisherman, "I will not let thee out; it is in vain to talk of it; I am just going to throw thee into the bottom of the sea." "Hear me one word more," cried the genie; "I promise to do thee no hurt; nay, far from that, I will shew thee a way to become exceedingly rich."
The hope of delivering himself from poverty, prevailed with the fisherman. "I could listen to thee," said he, "were there any credit to be given to thy word; swear to me by the great name of God, that you will faithfully perform what you promise, and I will open the vessel; I do not believe you will dare to break such an oath."
The genie swore to him, upon which the fisherman immediately took off the covering of the vessel. At that instant the smoke ascended, and the genie having resumed his form, the first thing he did was to kick the vessel into the sea. This action alarmed the fisherman. "Genie," said he, "will not you keep the oath you just now made? And must I say to you, as the physician Douban said to the Grecian king, suffer me to live, and God will prolong your days."
The genie laughed at the fisherman's fear, and answered, "No, fisherman, be not afraid, I only did it to divert myself, and to see if thou wouldst be alarmed at it: but to convince thee that I am in earnest, take thy nets and follow me." As he spoke these words, he walked before the fisherman, who having taken up his nets, followed him, but with some distrust. They passed by the town, and came to the top of a mountain, from whence they descended into a vast plain, which brought them to a lake, that lay betwixt four hills.
