Sophocles is considered one of the great ancient Greek tragedians. Among Sophocles' most famous plays are Oedipus the King, Oedipus at Colonus, and Antigone. These plays follow the fall of the great king, Oedipus, and later the tragedies that his children suffer. The Oedipus plays have had a wide-reaching influence and are particularly notable for inspiring Sigmund Freud?s theory of the Oedipus Complex, which describes a stage of psychological development in which a child sees their father as an adversarial competitor for his or her mother?s attention. These plays all deal in some way with the will of man vs. the will of the gods. Self-injury and suicide also plague the family until the end. It seems that Oedipus's family is never quite capable of escaping the pollution of his terrible mistakes.
