Atlantis
Atlantis is a legendary island empire introduced by the ancient Greek philosopher Plato in his dialogues Timaeus and Critias around 360 BCE, depicted as a vast, advanced civilization located beyond the Pillars of Hercules in the Atlantic Ocean, larger than Libya and Asia combined, with concentric rings of water and land, grand temples, and a powerful navy that subjugated parts of Europe and Africa before being defeated by an ancient Athenian confederacy and catastrophically sunk into the sea by earthquakes and floods within a day due to its inhabitants' descent into greed and impiety.[1][2]
Plato frames the tale as an oral tradition passed from Egyptian priests to the Athenian lawgiver Solon, purportedly recounting events 9,000 years prior, yet no independent ancient sources corroborate it, and the narrative's elaborate details serve as an allegorical device to illustrate philosophical ideals of governance, contrasting the virtuous, unified prehistoric Athens—embodying Platonic justice—with Atlantis's hubris-driven tyranny as a cautionary exemplar of societal decay.[3][4][5]
Scholarly consensus, grounded in textual analysis and absence of corroborating evidence, regards Atlantis as Plato's invention rather than historical fact, with proposed real-world inspirations like the Minoan eruption or Tartessos dismissed due to mismatches in scale, timeline, and geography; pseudohistorical interpretations persist in popular culture but lack empirical support from archaeology or geology.[3][6][7]
