Now "The Arabian Nights," some of which, but not nearly all, are given in this volume, are only fairy tales of the East. The people of Asia, Arabia, and Persia told them in their own way, not for children, but for grown-up people. There were no novels then, nor any printed books, of course; but there were people whose profession it was to amuse men and women by telling tales. They dressed the fairy stories up, and made the characters good Mahommedans, living in Bagdad or India. The events were often supposed to happen in the reign of the great Caliph, or ruler of the Faithful, Haroun al Raschid, who lived in Bagdad in 786-808 A.D. The vizir who accompanies the Caliph was also a real person of the great family of the Barmecides. He was put to death by the Caliph in a very cruel way, nobody ever knew why.
