A delightfully comic tale of mistaken identities, Twelfth Night revolves around the physical likeness between Sebastian and his twin sister, Viola, each of whom, when separated after a shipwreck, believes the other to be dead. The theatrical romp begins when Viola assumes the identity of Cesario, a page in the household of the Duke of Orsino. The Duke is enamored of the Countess Olivia, who spurns him for the newly arrived young page. The comical machinations of Malvolio, Sir Toby Belch, the maid Maria, and Sir Andrew Aguecheek add to the ensuing confusion — all of which is pleasantly resolved when Viola and Sebastian meet once again. Filled with some of the finest comedic scenes in the English language, this entertaining masterpiece remains one of Shakespeare's most popular and most performed comedies.
