The "Bacchae" is a tragedy written by the ancient Greek playwright Euripides. It tells the story of Dionysus, the god of wine and revelry, who returns to his birthplace, Thebes, to seek recognition and revenge against those who deny his divinity. The play explores themes of madness, the duality of human nature, and the conflict between civilization and primal instincts. In the narrative, Pentheus, the king of Thebes, opposes the worship of Dionysus and attempts to suppress the god's followers, the Maenads. This leads to his downfall as he is ultimately lured into a trap, resulting in tragic consequences. The play highlights the power of the divine and the dangers of hubris.
