The Arabian Nights is a collection of stories within stories, also known as "frames." One narrator's story contains or frames another narrator's story. The outer or first frame is the story of the King who, in revenge for the infidelity of his first wife, marries a new maiden every night, takes her virginity, and slays her in the morning. This frame contains the second frame of Scheherazade's story. In order to preserve her life, Scheherazade tells a seemingly endless story, and in her story, characters begin to tell their stories (additional frames).
