The three plays of this book (Oedipus the King (also called Oedipus Tyrannus or by its Latin title Oedipus Rex), Oedipus at Colonus and Antigone), also known as the Theban plays, concern the fate of Thebes during and after the reign of King Oedipus. Each of the plays relates to the tale of the mythological Oedipus, who killed his father and married his mother without knowledge that they were his parents. His family is fated to be doomed for three generations. Sophocles wrote the three plays for separate festival competitions, many years apart. Not only are the Theban plays not a true trilogy (three plays presented as a continuous narrative) but they are not even an intentional series and contain some inconsistencies among them. He also wrote other plays having to do with Thebes, such as the Epigoni, of which only fragments have survived.
