Ancient Greek literature
Seven works of Sophocles have survived, the most acclaimed of which are the three Theban plays, which center around the story of Oedipus and his offspring. The Theban Trilogy consists of "Oedipus the King", "Oedipus at Colonus", and "Antigone". Although the plays are often called a "trilogy," they were actually written many years apart. "Antigone", the last of the three plays sequentially, was actually first to be written, having been composed in 441 BC, towards the beginning of Sophocles's career. "Oedipus the King", the most famous of the three, was written around 429 BC at the midpoint of Sophocles's career. "Oedipus at Colonus", the second of the three plays chronologically, was actually Sophocles's last play and was performed in 401 BC, after Sophocles's death.
Sophocles
Thereafter, Sophocles emerged victorious in dramatic competitions at 18 Dionysia and 6 Lenaia festivals. In addition to innovations in dramatic structure, Sophocles' work is also known for its deeper development of characters than earlier playwrights. His reputation was such that foreign rulers invited him to attend their courts, although unlike Aeschylus who died in Sicily, or Euripides who spent time in Macedon, Sophocles never accepted any of these invitations. Aristotle used Sophocles' "Oedipus Rex" in his "Poetics" (c. 335 BC) as an example of the highest achievement in tragedy, which suggests the high esteem in which his work was held by later Greeks.
