“Of glass it is,” replied the man, sighing more heavily than ever; “but the glass of it was tempered in the flames of hell. An imp lives in it, and that is the shadow we behold there moving: or so I suppose. If any man buy this bottle the imp is at his command; all that he desires—love, fame, money, houses like this house, ay, or a city like this city—all are his at the word uttered. Napoleon had this bottle, and by it he grew to be the king of the world; but he sold it at the last, and fell. Captain Cook had this bottle, and by it he found his way to so many islands; but he, too, sold it, and was slain upon Hawaii. For, once it is sold, the power goes and the protection; and unless a man remain content with what he has, ill will befall him.”–Robert Louis Stevenson (The Bottle Imp)
