''Prometheus Unbound'' ( grc, Προμηθεὺς Λυόμενος, ''Promētheus Lyomenos'') is a fragmentary play in the ''Prometheia'' trilogy attributed to the 5th-century BC Ancient Greece, Greek tragedian Aeschylus, thought to have followed ''Prometheus Bound''. ''Prometheus Unbound'' was probably followed by ''Prometheus the Fire-Bringer''. It is concerned with the torments of the Greek mythological figure Prometheus who defies the gods and proceeds to give fire to humanity (theft of fire), for which he is subjected to eternal punishment and suffering at the hands of Zeus.
The text of the ''Unbound'' survives only in eleven fragments preserved by later authors. Nevertheless, these fragments, combined with prophetic statements made in the first play of the trilogy, allow the reconstruction of a broad outline.
A lengthy fragment translated into Latin by the Ancient Rome, Roman statesman Cicero indicates that the play would have opened with Prometheus visited by a chorus of Titan (mythology), Titans. Though Zeus had imprisoned them in Tartarus at the conclusion of the Titanomachy, he has at long last granted them clemency. This perhaps foreshadows Zeus's eventual reconciliation with Prometheus in the trilogy's third installment. Prometheus complains about his torment just as he had to the chorus of Oceanids in ''Prometheus Bound''. As the ''dramatis personae'' of ''Prometheus Bound'' erroneously lists Gaia (mythology), Gaea, it has been suggested that she is next to visit Prometheus in this play, in a sympathetic role that echoes Oceanus' turn in the first play. Finally, the faulty ''dramatis personae'' mentioned above and several fragments indicate that Heracles visits the Titan just as Io (mythology), Io had in ''Prometheus Bound''. Heracles kills the eagle that had been torturing Prometheus by eating his regenerating liver every day and frees the Titan.
Again mirroring events in the previous play, Prometheus forecasts the travels of Hercules as he concludes his Twelve Labours. The play thus concludes with Prometheus free from the torments of Zeus, but the Titan and Olympian have yet to reconcile.
It inspired the play Prometheus Unbound (Shelley), of the same title by Percy Bysshe Shelley.
