Corinth, Delphi, Phocis and Thebes are the places to which Oedipus journeys in "Oedipus Rex" by Sophocles (495 B.C.E. - 405 B.C.E.).
Specifically, Oedipus is transported in infancy from his native Thebes to Corinth. As a young man, he leaves Thebes to consult the Delphic oracle. He makes the decision to move to Thebes after hearing his fate as his father's killer and his mother's husband. He passes through Phocis by the roads branching off of the Delphi-Daulia intersection. He resides in Thebes until his overthrow and exile.
"Rex" is Latin for "King". Oedipus Rex means "Oedipus the King".
Thebes is the setting of Oedipus Rex because it is the place where the story begins.
'King' is an English equivalent of 'Rex' in the play 'Oedipus Rex'.
The shepherd in Oedipus Rex is the person who rescues Oedipus Rex as a child. The shepherd also confirms the main character's fate.
Oedipus Rex, Oedipus at Colonus, and Antigone
Oedipus Rex is part of a four part collection of plays, three tradgedies and a comedy. We do not have the Comedy but the three tradgedies are "Oedipus Rex", "Oedipus at Colonus", and "Antigone".
Oedipus
Sophocles, an Ancient Greek playwright, wrote Oedipus Rex.
The ancient Greek city of Thebes is the geographic location of the play 'Oedipus Rex'. That's where the action takes place. But there are references to other places such as Apollo's Shrine, Corinth, and Delphi.
Antigone, Oedipus Rex, Oedipus at Colonus
Laius was the father of Oedipus who Oedipus killed.
