Editing Prometheus Bound (section)

==Prometheus Trilogy==
There is evidence that ''Prometheus Bound'' was the first play in a trilogy conventionally called the ''[[Prometheia]]'', but the other two plays, ''[[Prometheus Unbound (Aeschylus)|Prometheus Unbound]]'' and ''[[Prometheus the Fire-Bringer]]'', survive only in fragments. In ''Prometheus Unbound'', Heracles frees Prometheus from his chains and kills the eagle that had been sent daily to eat the Titan's perpetually [[Liver regeneration|regenerating liver]]. Perhaps foreshadowing his eventual reconciliation with Prometheus, we learn that Zeus has released the other Titans whom he imprisoned at the conclusion of the Titanomachy. In ''Prometheus the Fire-Bringer'', the Titan finally warns Zeus not to lie with the sea nymph [[Thetis]], for she is fated to give birth to a son greater than the father. Not wishing to be overthrown, Zeus would later marry Thetis off to the mortal [[Peleus]]; the product of that union will be [[Achilles]], Greek hero of the [[Trojan War]]. Grateful for the warning, Zeus finally reconciles with Prometheus.
