Atlantas Plaque

Atlantis (in Greek, Ἀτλαντὶς νῆσος, "island of Atlas") is a legendary island first mentioned in Plato's dialogues Timaeus and Critias, written about 360 BC. According to Plato, Atlantis was a naval power lying "in front of the Pillars of Hercules" that conquered many parts of Western Europe and Africa 9,000 years before the time of Solon, or approximately 9600 BC. After a failed attempt to invade Athens, Atlantis sank into the ocean "in a single day and night of misfortune".
