Pericles, Prince of Tyre is a Jacobean play written at least in part by William Shakespeare and included in modern editions of his collected works despite questions over its authorship, as it was not included in the First Folio. Modern editors generally agree that Shakespeare is responsible for almost exactly half the play - the main portion after scene 9 that follows the story of Pericles and Marina. Modern textual studies indicate that the first two acts of 835 lines detailing the many voyages of Pericles were written by a collaborator, which strong evidence suggests to have been the dramatist and pamphleteer George Wilkins. William Shakespeare (circa 1564 - 23 April 1616) was an English poet and playwright, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon." His surviving works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and several other poems. His plays have been translated into every major living language and are performed more often than those of any other playwright.
