The third actor and the use of a more intricate story structure are only two of the numerous improvements in the tragedy genre attributed to Sophocles. His plays are especially renowned for their consideration of difficult moral dilemmas and their more realistic characters. One of Sophocles' most well-known plays is-
• Oedipus the King (429 BC), which tells the story of a man who unintentionally kills his father and weds his mother.
• Antigone (442 BC): This drama tells the story of a woman who breaches city-state law in order to bury her brother.
• Electra (413 BC): A drama about a lady seeking retribution for her father's death.
