Samuel Butler, the author of The Way of All Flesh, and Erewhon, believed that The Odyssey was written by a Sicilian woman, not Homer. According to Butler, The Odyssey takes places on the coast of Sicily, rather than Greece. Butler investigates this theory in the work The Authoress of The Odyssey. Interestingly, Robert Graves, the famous poet and author of I, Claudius agreed, and further investigated this theory in this novel Homer's Daughter.
Perhaps I'm new to this game, but I thought Homer was generally considered to be THE writer of his works, unlike Shakespeare, who, depending on the week, can be the Earl of Oxford, a woman, a Catholic, etc. Homer as a woman...who knew?
