In Greek mythology, Antigone (/ænˈtɪɡəni/ ann-TIG-ə-nee; Ancient Greek: Ἀντιγόνη) is the daughter of Oedipus and either his mother Jocasta or, in another variation of the myth, Euryganeia. She is a sister of Polynices, Eteocles, and Ismene. The meaning of the name is, as in the case of the masculine equivalent Antigonus, "worthy of one's parents" or "in place of one's parents". She appears in the three 5th century BC tragic plays written by Sophocles, known as the three Theban plays, and she is the main protagonist of the eponymous tragedy Antigone.
