Example Input: Oedipus Rex, also known by its Greek title, Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος IPA: (oidípuːs týranːos)), or Oedipus the King, is an Athenian tragedy by Sophocles that was first performed around 429 BC. Originally, to the ancient Greeks, the title was simply Oedipus (Οἰδίπους), as it is referred to by Aristotle in the Poetics. It is thought to have been renamed Oedipus Tyrannus to distinguish it from another of Sophocles' plays, Oedipus at Colonus. In antiquity, the term 'tyrant' referred to a ruler, but it did not necessarily have a negative connotation.

Viola (who is disguised as Cesario) 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. The play expanded on the musical interludes and riotous disorder expected of the occasion, with plot elements drawn from the short story 'Of Apollonius and Silla' by Barnabe Rich, based on a story by Matteo Bandello. The first recorded performance was on 2 February 1602, at Candlemas, the formal end of Christmastide in the year's calendar. The play was not published until its inclusion in the 1623 First Folio.
