In 1917 an Austrian author claims that Francis Bacon was the author of both Shakespeare and Don Quixote. One key proof is the frequency of unique phrases in Bacon's diaries which reappear verbatim in both Shakespeare and Don Quixote.

Don Quixote states that "the Arabian historian Cid Hamete Benengeli wrote our story." "Cid" means "Lord." "Hamete" could mean either "Bacon" or "Hamlet." "Ben" means "son," and "engeli" is Latin for"England." Thus, "Cid Hamete Benengeli" is "Lord Hamlet, Son of England," the author of our story. - Sir Francis Bacon's New Advancement of Learning
