The main frame story concerns a Persian king and his new bride. He is shocked to discover that his brother's wife is unfaithful; discovering his own wife's infidelity has been even more flagrant, he has her but in his bitterness and grief decides that all women are the same. The king, Shahryar, begins to marry a succession of virgins only to execute each one the next morning, before she has a chance to dishonour him. Eventually the vizier, whose duty it is to provide them, cannot find any more virgins. Scheherazade, the vizier's daughter, offers herself as the next bride and her father reluctantly agrees. On the night of their marriage, Scheherazade begins to tell the king a tale, but does not end it. The king, curious about how the story ends, is thus forced to postpone her execution in order to hear the conclusion. The next night, as soon as she finishes the tale, she begins (and only begins) a new one, and the king, eager to hear the conclusion, postpones her execution once again. So it goes on for 1,001 nights. The tales vary they include historical tales, love stories, tragedies, comedies, poems, burlesques and various forms of erotica. Numerous stories depict Jinns, Ghouls, Apes, sorcerers, magicians, and legendary places, which are often intermingled with real people and geography, not always rationally; common protagonists include the historical Abbasid caliph Harun al-Rashid, his Grand Vizier, Jafar al-Barmaki, and his alleged court poet Abu Nuwas, despite the fact that these figures lived some 200 years after the fall of the Sassanid Empire in which the frame tale of Scheherazade is set. Sometimes a character in Scheherazade's tale will begin telling other characters a story of his own, and that story may have another one told within it, resulting in a richly layered narrative texture.
