"Being returned from my sixth voyage," said Sinbad, "I absolutely laid aside all thoughts of travelling; for, besides that my age now required rest, I was resolved no more to expose myself to such risks as I had encountered; so that I thought of nothing but to pass the rest of my days in tranquillity. One day, however, as I was treating my friends, one of my servants came and told me that an officer of the caliph's inquired for me. I rose from table, and went to him. 'The caliph,' said he, 'has sent me to tell you that he must speak with you.' I followed the officer to the palace, where, being presented to the caliph, I saluted him by prostrating myself at his feet. 'Sinbad,' said he to me, 'I stand in need of your service; you must carry my answer and present to the King of Serendib. It is but just I should return his civility.' "This command of the caliph was to me like a clap of thunder. 'Commander of the Faithful,' I replied, 'I am ready to do whatever your majesty shall think fit to command; but I beseech you most humbly to consider what I have undergone. I have also made a vow never to go out of Bagdad.' Hence I took occasion to give him a full and particular account of all my adventures, which he had the patience to hear out. "As soon as I had finished, 'I confess,' said he, 'that the things you tell me are very extraordinary, yet you must for my sake undertake this voyage which I propose to you. You will only have to go to the isle of Serendib, and deliver the commission which I give you, for you know it would not comport with my dignity to be indebted to the king of that island.' Perceiving that the caliph insisted upon my compliance, I submitted, and told him that I was willing to obey. He was very well pleased, and ordered me one thousand sequins for the expenses of my journey. "I prepared for my departure in a few days, and as soon as the caliph's letter and present were delivered to me, I went to Bussorah, where I embarked, and had a very happy voyage. Having arrived at the isle of Serendib, I acquainted the king's ministers with my commission, and prayed them to get me speedy audience. They did so, and I was conducted to the palace, where I saluted the king by prostration, according to custom. That prince knew me immediately, and testified very great joy at seeing me, 'Sinbad,' said he, 'you are welcome; I have many times thought of you since you departed; I bless the day on which we see one another once more.' I made my compliments to him, and after having thanked him for his kindness, delivered the caliph's letter and present, which he received with all imaginable satisfaction.
