Crusoe: Daniel Defoe, Robert Knox and the Creation of a Myth

Several miles south another old man, Robert Knox, sits bent over a heavy volume - the only book he has written, published nearly forty years before. The large folio is now worn and tattered, crammed with extra pages covered in notes and emendations.

A leaner copy of Knox's book is also on the shelf in Defoe's library, perhaps even open on the table as he writes. The title page distils its contents: 'An Historical Relation of the Island of Ceylon in the East Indies: Together with an Account of the Detaining in Captivity of the Author and diverse other Englishmen now Living there and of the Author's Miraculous Escape. Illustrated with Figures and a Map of the Island. By Robert Knox, a Captive there near Twenty Years'.

Knox's Historical Relationwas a best-seller when it was published in 1681, just a year after he escaped from Ceylon and returned to England. But by 1719, despite Knox's efforts to have a revised edition published, it has long been out of print.

If Defoe had died in 1718, the year before he wrote Robinson Crusoe, few of us would have heard of him. He is principally remembered for this book and its hero. They have a life of their own: in the years since it was published, Crusoehas been abridged, imitated, parodied, dramatized, turned into opera, pantomime, comic books and cartoons, made into a string of films, adapted for reality television and translated into every written language.

Where did Crusoe come from? And what is the secret of his endurance? Crusoe explores the intertwined lives of two real men: Daniel Defoe and Robert Knox and the character and book that emerged from their peculiar conjunction. It is the biography of a book and its hero, the story of Defoe, the man who wrote Robinson Crusoe, and of Robert Knox, the man who was Crusoe.
