Treasure Island is an adventure novel by Scottish author Robert Louis Stevenson, narrating a tale of "buccaneers and buried gold." First published as a book on 14 November 1883 by Cassell & Co., it was originally serialized in the children's magazine Young Folks between 1881 and 1882 under the title Treasure Island or, the mutiny of the Hispaniola with Stevenson adopting the pseudonym Captain George North. Traditionally considered a coming-of-age story, Treasure Island is a tale noted for its atmosphere, characters and action, and also as a wry commentary on the ambiguity of morality - as seen in Long John Silver - unusual for children's literature. It is one of the most frequently dramatized of all novels. The influence of Treasure Island on popular perceptions of pirates is enormous, including such elements as treasure maps marked with an "X," schooners, the Black Spot, tropical islands, and one-legged seamen bearing parrots on their shoulders.
