Sophocles (495 BC-405 BC) was a famous and successful Athenian writer of tragedies in his own lifetime. Of his 120 plays, only 7 have survived. Oedipus the King, also called Oedipus Tyrannos or Oedipus Rex, written around 420 BC, has long been regarded not only as his finest play but also as the purest and most powerful expression of Greek tragic drama.
Oedipus, a stranger to Thebes, became king of the city after the murder of king Laius, about fifteen or sixteen years before the start of the play. He was offered the throne because he was successful in saving the city from the Sphinx, an event referred to repeatedly in the text of the play. He married Laius’ widow, Jocasta, and had four children with her, two sons, Eteocles and Polyneices, and two daughters, Antigone and Ismene.
