Pythia plays host to to Rhea as she seeks to hide from her husband, the mad god Cronus. Pythia was the name given the Oracle at Delphi. In later years, Apollo would be the god of the temple there, but of course at this time, an age before the birth of Apollo, or even Apollo’s own father, Zeus, it is one of the Titans who would ultimately be the god of Delphi in its earliest form.
Rhea, knowing what Cronus will do when he finds her pregnant again, has fled from the palace in an effort to save her unborn child, the Olympian God, Poseidon. It is hopeless though, as Cronus tracks her down. Like many abusers, he blames her for being pregnant, though as we all know, it takes two to tango.
Ultimately, like Hera before him, Poseidon is swallowed by his father. One more victim of the curse of Uranus and Nix.
