Short answers, pulled from the story.
George Wilkins is the writer who co-authored the first two acts of Pericles, Prince of Tyre. Modern textual analysis attributes approximately 827 lines to William Shakespeare and 835 lines to George Wilkins.
Scholars date the composition of Pericles, Prince of Tyre to 1607 or early 1608 based on literary connections. The only surviving text from the original production appeared as a quarto edition printed in 1609 by Henry Gosson.
The play draws its plot primarily from John Gower's Confessio Amantis written in 1393 and Lawrence Twine's prose adaptation The Pattern of Painful Adventures published around 1576. George Wilkins also released a prose version titled The Painful Adventures of Pericles Prince of Tyre in 1608.
Pericles, Prince of Tyre did not appear in the First Folio of 1623 because editors added it thirty-six years later in the third impression of the Third Folio in 1664. William Jaggard had previously included the play in his False Folio of 1619.
The text appears to be one of seventeen plays printed during Shakespeare's lifetime and was reprinted five times between 1609 and 1635. Subsequent editions appeared in 1611, 1619, 1630, and 1635 after the initial quarto edition.
