The Grecian king (says the fisherman to the genie) was not satisfied with having admitted the physician Douban to his table, but towards night, when he was about dismissing the company, he caused him to be clad in a long rich robe, like unto those which his favourites usually wore in his presence; and, besides that, he ordered him two thousand sequins. The next day, and the day following, he was very familiar with him. In short, this prince, thinking that he could never enough acknowledge the obligations he lay under to that able physician, bestowed every day new favours upon him. But this king had a grand vizier that was avaricious, envious, and naturally capable of all sorts of mischief; he could not see, without envy, the presents that were given to the physician, whose other merits had begun to make him jealous, and therefore he resolved to lessen him in the king's esteem. To effect this, he went to the king, and told him in private that he had some advice to give him which was of the greatest concernment. The king having asked what it was, Sir, said he, it is very dangerous for a monarch to put confidence in a man whose fidelity he never tried. Though you heap favours upon the physician Douban, and show him all the familiarity that may be, your majesty does not know but he may be a traitor at the same time, and came on purpose to this court to kill you. From whom have you this, answered the king, that you dare tell it me? Consider to whom you speak, and that you advance a thing which I shall not easily believe. Sir, replied the vizier, I am very well informed of what I have had the honour to represent to your majesty, therefore do not let your dangerous confidence grow to a further height; if your majesty be asleep, be pleased to awake; for I do once more repeat it, that the physician Douban did not leave the heart of Greece, his country, nor come hither to settle himself at your court, but to execute that horrid design which I have just now hinted to you.
