Bibliotheca

Apollodorus

Apollodorus names Periboea (not Sophocles' Merope) as wife of Polybus and foster-mother of the exposed Oedipus — the Corinthian queen who raises the Theban foundling as her own.

Periboea

Queen of Corinth by Polybus — foster mother of Oedipus in the Apollodoran strand; Sophocles and many modern tellings call her Merope instead.

Polybus of Corinth

Periboea's husband — the childless king who adopts the infant from Cithaeron and whose supposed death frees Oedipus to walk toward Thebes.

Oedipus Rex

Sophocles

Sophocles' tragedy keeps the Corinthian foster-parents at the plot's hinge — the gentle house Oedipus flees, though the queen's name there is Merope rather than Periboea.
