Treasure Island (originally The Sea Cook: A Story for Boys) is an adventure novel (1881–1882) by Scottish author Robert Louis Stevenson, narrating a tale of "buccaneers and buried gold." Its influence is enormous on popular perceptions of pirates, making popular such elements as treasure maps marked with an "X", schooners, the Black Spot, tropical islands, and one-legged seamen bearing parrots on their shoulders.
