Atlantis is a legendary “lost” island subcontinent often idealized as an advanced, utopian society holding wisdom that could bring world peace. The idea of Atlantis has captivated dreamers, occultists and New Agers for generations. Debate about whether Atlantis truly existed has lasted for thousands of years. Plato’s “dialogues” from around 360 B.C. are the only known historical sources of information about the iconic city. Plato said the island he called Atlantis “in a single day and night … disappeared into the depths of the sea.” Taprobana is actually Ceylon, although it was sometimes confused with Sumatra on some maps. Taprobana, as it was called on most early maps, was an important post for trade between the east and the west, and was drawn too large on many maps because of its importance.
