Atlantis
Atlantis is a fictional island mentioned in an allegory on the hubris of nations in Plato's works Timaeus and Critias, wherein it represents the antagonist naval power that besieges "Ancient Athens", the pseudo-historic embodiment of Plato's ideal state in The Republic. In the story, Athens repels the Atlantean attack unlike any other nation of the known world, supposedly bearing witness to the superiority of Plato's concept of a state. The story concludes with Atlantis falling out of favor with the deities and submerging into the Atlantic Ocean. Despite its minor importance in Plato's work, the Atlantis story has had a considerable impact on literature. The allegorical aspect of Atlantis was taken up in utopian works of several Renaissance writers, such as Francis Bacon's New Atlantis and Thomas More's Utopia.
