THE SLEEPER AWAKENED
him a warm invitation to spend the night under his roof, and promising him the best of entertainment. Indeed, being of a gay and merry disposition, he sought even to choose one of a melancholy cast, so that he might exercise his wit upon him and cause his face to shine with mirth. In the morning he would send his guest away with his blessing, having explained to him the nature of his oath and exacted his promise to regard him henceforth as a perfect stranger. 'And so, farewell! May God conduct you in safe and pleasant ways!'
For a long time he behaved in this manner, providing the best of entertainment and adhering closely to his oath. At length there came an evening when he was waiting as usual on the bridge, and it chanced that the caliph of Baghdad himself came by, disguised as a merchant—a favourite amusement of his when he wished to traverse the ways of the city and see how his people fared. Abu Hasan looked at him as he passed, and taking him, by his dress and the stout slave following him, for a merchant from Moussul, and therefore a stranger in the city, he accosted him.
'Sir,' he said, saluting gracefully, 'permit me to compliment you on your happy arrival in Baghdad. Not, indeed, to show you that this is a hospitable city, but rather that I may have the honour of your company at my house, I beg that you will accept my invitation to come and sup with me and rest yourself after the fatigue of your journey.'
The caliph, always in the mood for an adventure, accepted gladly, and together they repaired to Hasan's abode, the slave following after. When they arrived they found supper laid for two, and in the most sumptuous style. Hasan, treating his guest with every courtesy, seated him in the place of honour.
The apartment was most luxurious. On one side trickled streams of water through silver channels half hidden among rare ferns. On another side golden fountains played in cool grottoes, and, over all, a soft light falling from a wonderful lamp overhead wrapped the richness of the place in a dreamy glamour.
