"Prometheus Bound" also includes two mythic innovations of omission. The first is the absence of Pandora's story in connection with Prometheus' own. Instead, Aeschylus includes this one oblique allusion to Pandora and her jar that contained Hope (252): " caused blind hopes to live in the hearts of men." Second, Aeschylus makes no mention of the sacrifice-trick played against Zeus in the "Theogony". The four tragedies of Prometheus attributed to Aeschylus, most of which are lost to the passages of time into antiquity, are "Prometheus Bound" ("Prometheus Desmotes"), "Prometheus Unbound" ("Lyomenos"), "Prometheus the Fire Bringer" ("Pyrphoros"), and "Prometheus the Fire Kindler" ("Pyrkaeus").
