Twelfth Night, The Winter's Tale & Pericles, Prince of Tyre

Twelfth Night, Or What You Will is a comedy by William Shakespeare, based on the short story "Of Apolonius and Silla" by Barnabe Rich. It is named after the Twelfth Night holiday of the Christmas season. It was written around 1601 and first published in the First Folio in 1623. The main title is believed to be an afterthought, created after John Marston premiered a play titled What You Will during the course of the writing.

The Winter's Tale is a play by William Shakespeare, first published in the First Folio in 1623. Although it was listed as a comedy when it first appeared, some modern editors have relabeled the play a romance. Some critics, among them W. W. Lawrence (Lawrence, 9-13), consider it to be one of Shakespeare's "problem plays", because the first three acts are filled with intense psychological drama, while the last two acts are comedic and supply a happy ending.

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.
