The 'Prometheus' transports the reader to another world. The characters are gods, the time is the remote past, the place a desolate waste in Scythia, on the confines of the Northern Ocean. Prometheus had sinned against the authority of Zeus. Zeus wished to destroy the old race of mankind; but Prometheus gave them fire, taught them arts and handicrafts, developed in them thought and consciousness, and so assured both their existence and their happiness. The play deals with his punishment. Prometheus is borne upon the scene by Force and Strength, and is nailed to a lofty cliff by Hephaestus. His appeal to Nature, when his tormentors depart and he is left alone, is peculiarly pathetic. The daughters of Oceanus, constituting the Chorus, who have heard the sound of the hammer in their ocean cave, are now borne in aloft on a winged car, and bewail the fate of the outraged god. Oceanus appears upon a winged steed, and offers his mediation; but this is scornfully rejected. The resolution of Prometheus to resist Zeus to the last is strengthened by the coming of Io. She too, as it seems, is a victim of the Ruler of the Universe; driven by the jealous wrath of Hera, she roams from land to land. She tells the tale of her sad wandering, and finally rushes from the scene in frenzy, crazed by the sting of the gadfly that Hera has sent to torment her. Prometheus knows a secret full of menace to Zeus. Relying on this, he prophesies his overthrow, and defies him to do his worst. Hermes is sent to demand with threats its revelation, but fails to accomplish his purpose. Prometheus insults and taunts him. Hermes warns the Chorus to leave, for Zeus is about to display his wrath. At first they refuse, but then fly affrighted: the cliff is rending and sinking, the elements are in wild tumult. As he sinks, about to be engulfed in the bowels of the earth, Prometheus cries:-- "Earth is rocking in space! And the thunders crash up with a roar upon roar, And the eddying lightnings flash fire in my face, And the whirlwinds are whirling the dust round and round, And the blasts of the winds universal leap free And blow each upon each with a passion of sound, And aether goes mingling in storm with the sea."
