Sophocles (495 B.C.E. - 405 B.C.E.) is the author of the play "Oedipus Rex."

Specifically, the original title of the play is "Oedipus Tyrannus." The play is better known under its Latin title, "Oedipus Rex." The Latin title is translated directly and literally into English as "Oedipus the King."

The play 'Oedipus at Colonus' is the opposite of 'Oedipus Rex'. The play 'Oedipus Rex' deals with Theban King Oedipus' rise to, and subsequent fall from, personal happiness and professional success. The play 'Oedipus at Colonus' deals with the King's humiliating, miserable time of exile and his ultimate return to favor with gods and mortals.
