Pericles, Prince of Tyre is a play written (at least in part) by William Shakespeare and included in modern editions of his collected works despite some questions over its authorship, as it was not included in the First Folio. Many modern editors believe that Shakespeare is responsible for the main portion of the play after scene 9 that follows the story of Pericles and Marina, and that the first two acts, detailing the many voyages of Pericles, were written by a relatively untalented reviser or collaborator, possibly George Wilkins.
