First performed around 429 BC at the City Dionysia in Athens, where it took second prize behind Aeschylus's nephew Philocles.
Second of Sophocles's three surviving Theban plays by composition (written after Antigone and before Oedipus at Colonus), though first in narrative chronology.
Repeatedly cited by Aristotle in the Poetics as the exemplar of tragedy, tracing Oedipus's search for King Laius's killer to Jocasta's suicide and his own self-blinding.
