That it is reliable and useful is what can be said about "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.) as a historical source for the study of ancient Greece.
Specifically, the play is reliable and useful in telling the story of Theban King Oedipus from the perspective of an educated Athenian transplanted dramatist of the fifth century B.C.E. Those who believe that Oedipus is an actual person rather than a mythological character may date his life to the thirteenth century B.C.E. But reardless, the play provides insights into ancient Greek religious beliefs and socio-political systems.

Athens is where Sophocles (495 B.C.E. - 405 B.C.E.) wrote "Oedipus Rex."Specifically, the ancient Greek dramatist was born in Colonus, Theban King Oedipus' death place. But Sophocles spent his adult life in nearby Athens, which was a cultural, economic and political center in ancient Greece. It was in his adopted city of Athens that Sophocles wrote his three plays on the life and times of Oedipus and of Oedipus' children.
"Oedipus the King" is the meaning of the title "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).Specifically, the title "Oedipus Rex" is in Latin. It is a translation of the original title of "Oedipus Tyrannus" in ancient Greek. But the Latin is not a literal translation since the Greek translates literally into English as "Oedipus the Tyrant."
"Oedipus Tyrannus" and "Oedipus the King" are two titles by which the play "Oedipus Rex" also is known.Specifically, "Oedipus Tyrannus" is the play's original title by ancient Greek playwright Sophocles (495 B.C.E. - 405 B.C.E.). "Oedipus Rex" is the title that is given to the Latin translation of the original Greek play. "Oedipus the King" is the title to the English translation.
