Greek sea gods conform to a single type: that of Homer's "halios geron" or Old Man of the Sea: Nereus, Proteus, Glaucus and Phorkys. These sea gods are not as powerful as Poseidon, the main god of the oceans and seas. Each one is a shape-shifter, a prophet, and the father of either radiantly beautiful nymphs or hideous monsters (or both, in the case of Phorkys). Nymphs and monsters blur, for Hesiod relates that Phorcys was wed to the "beautiful-cheeked" Ceto, whose name is merely the feminine of the monstrous Cetus, to whom Andromeda was due to be sacrificed. Each appearance in myth
The God Beneath the Sea finds Prometheus' hidden jar. Opening it, she releases malignant furies on mankind: madness, old age, vice and sickness. All that is left in the jar is a chrysalis that works as a healing balm. Hermes consoles the despairing Prometheus that hope was left behind for mankind, "for who knows what may unfold from a chrysalis?" Part III, "Gods and Men", begins with the tale of Lycaon turned to a wolf by Zeus after treating him with disrespect. Zeus begins a deluge. Prometheus shouts a warning to Deucalion, who makes a sea vessel to survive the storm with his wife, Pyrrha.
