Eco employed his education as a medievalist in his first novel The Name of the Rose (1980), a historical mystery set in a 14th-century monastery. Franciscan friar william of Baskerville, aided by his assistant Adso, a Benedictine novice, investigates a series of murders at a monastery that is to host an important religious debate. The novel contains many direct or indirect metatextual references to other sources, requiring the detective work of the reader to 'solve'. The title is unexplained in the book. As a symbol, the rose is ubiquitous enough not to confer any single meaning. There is a tribute to Jorge Luis Borges, a major influence on Eco, in the blind monk and librarian Jorge of Burgos: Borges, like the character Jorge, lived a celibate life consecrated to his passion for books, and also went blind in later life. william of Baskerville is a logically-minded Englishman who is a friar and a detective, and his name evokes both william of Ockham and Sherlock Holmes (by way of The Hound of the Baskervilles); several passages describing him are strongly reminiscent of Sir Arthur Conan Doyle's descriptions of Holmes. The underlying mystery of the murder is borrowed from the "Arabian Nights". The Name of the Rose was later made into a motion picture starring Sean Connery, F. Murray Abraham, Christian Slater and Ron Perlman, which follows the plot, though not the philosophical and historical themes, of the novel.
