Oedipus Rex, also known as Oedipus the King, is a Greek tragedy written by Sophocles around 429 BCE, considered one of the greatest works of classical literature. Set in the city of Thebes, the play follows King Oedipus, a man of intellect and determination, who seeks to save his city from a devastating plague by uncovering the murderer of the previous king, Laius. Unbeknownst to him, Oedipus himself is the culprit, having unwittingly fulfilled a prophecy that he would kill his father, Laius, and marry his mother, Jocasta. Through a series of revelations driven by Oedipus’s relentless pursuit of truth, the play explores themes of fate, free will, and the tragic consequences of human ignorance in the face of divine will. Its dramatic structure, rich characterization, and profound philosophical questions have made it a cornerstone of Western drama, influencing literature and thought for centuries.
