The book "Francis Bacon is Shakespeare" by the author Edwin Durning-Lawrence, knight, is devoted to one of the most interesting theories of mystery in the history of literature. In this work, the author considers the hypothesis that Francis Bacon, an outstanding English philosopher, activist and thinker of the 16th century, was actually the author of the works traditionally attributed to William Shakespeare. The author provides arguments that support this theory, based on textual analysis, stylistic features, and other evidence of overlapping biographical data of both writers. In addition to the main thesis about Bacon's authorship of Shakespeare's works, the book also contains a reprint of Bacon's own Promus of Formulas and Elegances, which helps to decipher his style and thoughts. This interesting study arouses interest and raises questions about the true nature and origin of literary masterpieces.
