The magnificence of the place, and the civility they received, inspired the calenders with high respect for the ladies: but, before they sat down, having by chance cast their eyes upon the porter, whom they saw clad almost like those devotees with whom they have continual disputes respecting several points of discipline, because they never shave their beards nor eye-brows; one of them said, "I believe we have got here one of our revolted Arabian brethren." The porter having his head warm with wine, took offence and with a fierce look, without stirring from his place, answered, "Sit you down, and do not meddle with what does not concern you: have you not read the inscription over the gate? Do not pretend to make people live after your fashion, but follow ours." "Honest man," said the calender, "do not put yourself in a passion; we should be sorry to give you the least occasion; on the contrary, we are ready to receive your commands." Upon which, to put an end to the dispute, the ladies interposed, and pacified them. When the calenders were seated, the ladies served them with meat; and Safie, being highly pleased with them, did not let them want for wine. After the calenders had eaten and drunk liberally, they signified to the ladies, that they wished to entertain them with a concert of music, if they had any instruments in the house, and would cause them to be brought: they willingly accepted the proposal, and fair Safie going to fetch them, returned again in a moment, and presented them with a flute of her own country fashion, another of the Persian, and a tabor. Each man took the instrument he liked, and all three together began to play a tune The ladies, who knew the words of a merry song that suited the air, joined the concert with their voices; but the words of the song made them now and then stop, and fall into excessive laughter. In the height of this diversion, when the company were in the midst of their jollity, a knocking was heard at the gate; Safie left off singing, and went to see who it was. The caliph Haroon al Rusheed was frequently in the habit of walking abroad in disguise by night, that he might discover if every thing was quiet in the city, and see that no disorders were committed.
