Ancient Greek literature
Seven works of Sophocles have survived, the most acclaimed of which are the three Theban plays, which center around the story of Oedipus and his offspring. The Theban Trilogy consists of "Oedipus the King", "Oedipus at Colonus", and "Antigone". Although the plays are often called a "trilogy," they were actually written many years apart. "Antigone", the last of the three plays sequentially, was actually first to be written, having been composed in 441 BC, towards the beginning of Sophocles's career. "Oedipus the King", the most famous of the three, was written around 429 BC at the midpoint of Sophocles's career. "Oedipus at Colonus", the second of the three plays chronologically, was actually Sophocles's last play and was performed in 401 BC, after Sophocles's death.
Antigone (Sophocles play)
An important issue still debated regarding Sophocles' "Antigone" is the problem of the second burial. When she poured dust over her brother's body, Antigone completed the burial rituals and thus fulfilled her duty to him. Having been properly buried, Polyneices' soul could proceed to the underworld whether or not the dust was removed from his body. However, Antigone went back after his body was uncovered and performed the ritual again, an act that seems to be completely unmotivated by anything other than a plot necessity so that she could be caught in the act of disobedience, leaving no doubt of her guilt. More than one commentator has suggested that it was the gods, not Antigone, who performed the first burial, citing both the guard's description of the scene and the chorus's observation.
