Atlantica Online is a MORPG set in the mythical land of Atlantis, which was first described by what western philosopher?
Atlantis Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος , "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 repels 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 deities and submerges into the Atlantic Ocean.
Heraclides Ponticus Heraclides Ponticus (Ancient Greek: Ἡρακλείδης ὁ Ποντικός "Herakleides"; c. 390 BC – c. 310 BC ) was a Greek philosopher and astronomer who was born in Heraclea Pontica, now Karadeniz Ereğli, Turkey, and migrated to Athens. He is best remembered for proposing that the Earth rotates on its axis, from west to east, once every 24 hours. He is also frequently hailed as the originator of the heliocentric theory, although this is doubted.
