Psychosexual development character Oedipus, who unwittingly killed his father, Laius, and sexually possessed his mother, Jocasta. Analogously, in the phallic stage, a girl's decisive psychosexual experience is the Electra complex, her daughter–mother competition for psychosexual possession of father. This psychological complex derives from the 5th-century BC Greek mythologic character Electra, who plotted matricidal revenge with Orestes, her brother, against Clytemnestra, their mother, and Aegisthus, their stepfather, for their murder of Agamemnon, their father, (cf. "Electra", by Sophocles). Initially, Freud equally applied the Oedipus complex to the psychosexual development of boys and girls, but later developed the female aspects of the theory as
Oedipus Rex ability, as seen in "Oedipus at Colonus". It is deliberately ironic that the "seer" can "see" better than Oedipus, despite being blind. In one line (Oedipus the king, 469), Tiresias says: ""So, you mock my blindness? Let me tell you this. You [Oedipus] with your precious eyes, you're blind to the corruption of your life ..."" (Robert Fagles 1984) Sigmund Freud in "Interpretation of Dreams" wrote a notable passage regarding of the destiny of Oedipus as well as the Oedipus complex. He analyzes why this play, "Oedipus Rex", written in Ancient Greece, is so effective even to a modern audience.
