Atlantis

Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, "island of Atlas") is the name of a legendary island and civilization, held as an allegorical myth, purely the invention of the Platonic school, by some, and as a formerly existing island and resident civilisation, now sunk beneath the ocean following a great cataclysm (similar to Kumari Kandam, Lemuria, or Mu), by others.
