Twelfth Night, or What You Will is a comedy by William Shakespeare, believed to have been written around 1601-02 as a Twelfth Night's entertainment for the close of the Christmas season. The play centres on the twins Viola and Sebastian, who are separated in a shipwreck. Viola (who is disguised as a boy) falls in love with Duke Orsino, who in turn is in love with the Countess Olivia. Upon meeting Viola, Countess Olivia falls in love with her thinking she is a man. Illyria, the setting of Twelfth Night, is important to the play's romantic atmosphere. Illyria was an ancient region of the Western Balkans whose coast (the eastern coast of the Adriatic Sea which is the only part of ancient Illyria which is relevant to the play) covered (from north to south) the coasts of modern-day Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Albania. It included the city-state of the Republic of Ragusa which has been proposed as the setting. Illyria may have been suggested by the Roman comedy Menaechmi, the plot of which also involves twins who are mistaken for each other. Illyria is also referred to as a site of pirates in Shakespeare's earlier play, Henry VI, Part 2. The names of most of the characters are Italian but some of the comic characters have English names. Oddly, the "Illyrian" lady Olivia has an English uncle, Sir Toby Belch. It has been noted that the play's setting also has other English allusions such as Viola's use of "Westward ho!", a typical cry of 16th-century London boatmen, and also Antonio's recommendation to Sebastian of "The Elephant" as where it is best to lodge in Illyria; The Elephant was a pub not far from the Globe Theatre. Viola is shipwrecked on the coast of Illyria and she comes ashore with the help of a Captain. She has lost contact with her twin brother, Sebastian, who she believes to be drowned. With the aid of the Captain, she disguises herself as a young man under the name Cesario, and enters the service of Duke Orsino. Duke Orsino has convinced himself that he is in love with Olivia, who is mourning the recent deaths of her father and brother. She refuses to see entertainments, be in the company of men, or accept love or marriage proposals from anyone, the Duke included, until seven years have passed. Duke Orsino then uses 'Cesario' as an intermediary to profess his passionate love before Olivia. Olivia, however, falls in love with 'Cesario', setting her at odds with her professed duty. In the meantime, Viola has fallen in love with the Duke Orsino, creating a love triangle among Duke Orsino, Olivia and Viola: Viola loves Duke Orsino, Duke Orsino loves Olivia, and Olivia loves Viola disguised as Cesario. In the comic subplot, several characters conspire to make Olivia's pompous steward, Malvolio, believe that Olivia has fallen for him. This involves Olivia's riotous uncle, Sir Toby Belch; another would-be suitor, a silly squire named Sir Andrew Aguecheek; her servants Maria and Fabian; and her melancholy fool, Feste. Sir Toby and Sir Andrew engage themselves in drinking and revelry, thus disturbing the peace of Olivia's household until late into the night, prompting Malvolio to chastise them. Sir Toby famously retorts, "Dost thou think, because thou art virtuous, there shall be no more cakes and ale?" (Act II, Scene III). Sir Toby, Sir Andrew, and Maria plan revenge on Malvolio. They convince Malvolio that Olivia is secretly in love with him by planting a love letter, written by Maria in Olivia's handwriting. It asks Malvolio to wear yellow stockings cross-gartered, to be rude to the rest of the servants, and to smile constantly in the presence of Olivia. Malvolio finds the letter and reacts in surprised delight. He starts acting out the contents of the letter to show Olivia his positive response. Olivia is shocked by the changes in Malvolio and leaves him to the contrivances of his tormentors.
