Oedipus at Colonus · Concept
Filial duty
Antigone and Ismene divide the labor of care — one walks beside the blind father daily, while sisters and brothers argue over inheritance and loyalty.
Family and filial duty organize the play’s emotional center. Antigone guides Oedipus, defies Theban threats, and stays when Ismene arrives with news of civil war. Ismene offers sisterly support but cannot replace Antigone’s constancy. Oedipus curses sons who waited for his death to fight over power, especially Polynices, who comes seeking blessing before battle.
The contrast with Creon’s abduction attempt sharpens the theme: Thebes wants the body for its own safety, not for love. Theseus, by contrast, protects Oedipus as guest. Students reading Antigone first should see Colonus as prehistory — the same Antigone who will bury a brother already learned loyalty at a blind father’s side. Use filial duty to connect private care to public fate: who tends the outcast determines who inherits divine favor.
