Plays of Sophocles - The Theban Plays - OEDIPUS THE KING - OEDIPUS AT COLONUS - ANTIGONE. The most famous tragedies of Sophocles feature Oedipus and also Antigone: they are generally known as the Theban plays, although each play was actually a part of a different tetralogy, the other members of which are now lost. Sophocles influenced the development of the drama, most importantly by adding a third actor, thereby reducing the importance of the chorus in the presentation of the plot. He also developed his characters to a greater extent than earlier playwrights such as Aeschylus. The Theban Plays The Theban plays consist of three plays: Oedipus the King (also called Oedipus Tyrannus or by its Latin title Oedipus Rex), Oedipus at Colonus and Antigone. All three plays concern the fate of Thebes during and after the reign of King Oedipus. They have often been published under a single cover.] Sophocles, however, 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. 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.
