Wikipedia said:In Greek mythology, Metis /ˈmiːtɨs/ (Μῆτις, "wisdom," "skill," or "craft") was of the Titan generation and, like several primordial figures, an Oceanid, in the sense that Metis was born of Oceanus and his sister Tethys, of an earlier age than Zeus and his siblings. Metis was the first great spouse of Zeus,[1] and also his cousin.[2] Zeus is himself titled Mêtieta, "the wise counsellor," in the Homeric poems.
"Zeus lay with Metis but immediately feared the consequences. It had been prophesied that Metis would bear extremely powerful children: the first, Athena and the second, a son more powerful than Zeus himself, who would eventually overthrow Zeus."[5]
In order to forestall these dire consequences, Zeus tricked her into turning herself into a fly and promptly swallowed her.[6] He was too late: Metis had already conceived a child. In time she began making a helmet and robe for her fetal daughter. The hammering as she made the helmet caused Zeus great pain, and Hephaestus either clove Zeus's head with an axe,[7] or hit it with a hammer at the river Triton, giving rise to Athena's birth. Athena leaped from Zeus's head, fully grown, armed, and armored, and Zeus was none the worse for the experience.
I don't think Greco-Roman myth ever went on to elaborate on the prophecy. But what if it did? Could there be a strain of messianic or eschatological thought within such myths about the coming of a new god who could overthrow Zeus? How would such an alternate myth form, could it affect Greek society like so many millenarian movements throughout time? Greek myth is usually thought to be fairly peaceful, with the deities being squabbling and petty as humans, and no end times as there are in say Norse or Mesoamerican religions. What if they did?
Also how would this affect Battlestar Galactica?
