When they came to the last of the supper and the princess knew that the wine had gotten the mastery in his head, she said to him, "We have in our country a custom, meknoweth not if you in this country use it or not." "And what is this custom?" asked the Maugrabin. "It is," answered she, "that, at the end of supper, each lover taketh the other's cup and drinketh it." So saying, she took his cup and filling it for herself with wine, bade the handmaid give him her cup, wherein was wine mingled with henbane, even as she had taught her how she should do, for that all the slaves and slave-girls in the palace wished his death and were at one against him with the Lady Bedrulbudour. So the damsel gave him the cup, and he, hearing the princess's words and seeing her drink in his cup and give him to drink in hers, deemed himself Iskender of the Horns, whenas he saw from her all this love. Then she bent towards him, swaying gracefully from side to side, and laying her hand on his, said, "O my life, here is thy cup with me and mine is with thee; thus do lovers drink one from other's cup." Then she kissed [613] his cup and drinking it off, set it down and came up to him and kissed him on the cheek; [614] whereat he was like to fly for joy and purposing to do even as she had done, raised the cup to his mouth and drank it all off, without looking if there were aught therein or not; but no sooner had he done this than he turned over on his back, like a dead man, and the cup fell from his hand.
