Prometheus Bound (Ancient Greek: Προμηθεὺς Δεσμώτης, romanized: Promētheús Desmṓtēs) is an ancient Greek tragedy traditionally attributed to Aeschylus and thought to have been composed sometime between 479 BC and the terminus ante quem of 424 BC. The tragedy is based on the myth of Prometheus, a Titan who defies Zeus, and protects and gives fire to mankind, for which he is subjected to the wrath of Zeus and punished.
