Is there a connection between Selkirk and Robinson Crusoe?

Yes, Selkirk was a real-life Scottish sailor who was marooned on an uninhabited island in the South Pacific for four years. His story inspired Daniel Defoe to write "Robinson Crusoe," a novel about a fictional character who is also marooned on a desert island. Defoe's work is considered a fictionalized account of Selkirk's experience.
