Delightfully comic tale revolves around the physical likeness between Sebastian and his twin sister, Viola. Filled with superb comic scenes, this delightful tale of mistaken identities remains one of Shakespeare's most popular and performed comedies.

'Twelfth Night, or What You Will' is a romantic comedy by William Shakespeare. The play centers on the twins Viola and Sebastian, who are separated in a shipwreck. Viola (who is disguised as Cesario) falls in love with the Duke Orsino, who in turn is in love with Countess Olivia. Upon meeting Viola, Countess Olivia falls in love with her thinking she is a man.

This play 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. Like many of Shakespeare's comedies, this one centers on mistaken identity. The leading character, Viola, is shipwrecked on the shores of Illyria during the opening scenes. She loses contact with her twin brother, Sebastian, whom she believes dead. Posing as a man and masquerading as a young page under the name Cesario, she enters the service of Duke Orsino. Orsino is in love with the bereaved Lady Olivia, whose brother has recently died and decides to use "Cesario" as an intermediary. Olivia, believing Viola to be a man, falls in love with this handsome and eloquent messenger. Viola, in turn, has fallen in love with the Duke, who also believes Viola is a man and who regards her as his confidant.
