Atlantis (, "island of
Atlas") is a
fictional island mentioned within an
allegory on the
hubris of nations in
Plato's works
Timaeus and
Critias, where it represents the
antagonist naval power that besieges "Ancient Athens", the
pseudo-historic embodiment of Plato's ideal state (see
The Republic). In the story, Athens was able to repel the Atlantean attack, unlike any other nation of the (western)
known world, supposedly giving testament to the superiority of Plato's concept of a state. At the end of the story, Atlantis eventually falls out of favor with the gods and famously submerges into the
Atlantic Ocean.
