An early example of the frame story, or framing device, is employed in the One Thousand and One Nights, in which the character Scheherazade narrates a set of tales (most often fairy tales) to the Sultan Shahriyar over many nights. Many of Scheherazade's tales are also frame stories, such as the Tale of Sindbad the Seaman and Sindbad the Landsman being a collection of adventures related by Sindbad the Seaman to Sindbad the Landsman. The concept of the frame story dates back to ancient Sanskrit literature, and was introduced into Persian and Arabic literature through the Panchatantra.
