The Atlantis

Atlantis (in Greek, Ἀτλαντὶς νῆσος, "island of Atlas") is the name of a legendary island first mentioned in Plato's dialogues Timaeus and Critias.[1]

In Plato's account, Atlantis, lying "beyond the Pillars of Heracles", was a naval power that conquered many parts of Western Europe and Africa 9,000 years before the time of Solon, or approximately 9500 BC. After a failed attempt to invade Athens, Atlantis sank into the ocean "in a single day and night of misfortune".
