Sophocles, born in 495 B.C. near Athens, wrote over 120 plays, with seven surviving today, including the renowned tragedy 'Oedipus Rex.' The story follows Oedipus, who unknowingly kills his father and marries his mother, leading to disastrous consequences including his self-inflicted blindness. Major themes include the quest for identity and truth, the nature of moral responsibility, and the interplay of sight and blindness.
