What does Antigone mean when she says, "O Oedipus, father and brother! Your marriage strikes from the grave to murder mine."? She believes that her fate is due in part to the curse caused by her father's actions. She knows that she can never have children because incest has made her sterile and unable to conceive. She feels a deeper sympathy toward her mother and father now that she herself is near death. She believes that the ghost of her father still haunts her, and because he is evil, he wants her to be unhappy.
