The Mystery of Atlantis — Truth or Legend Everything you know about the lost city of Atlantis comes from a single philosopher born in 427 BC. His name was Plato. Around 360 BC, the Greek thinker introduced Atlantis to the world in two specific dialogues: Timaeus and Critias. Plato claimed the story was passed down from the Greek statesman Solon, who allegedly heard it from Egyptian priests in the city of Sais. But here is the cold historical fact: Before Plato’s ink hit the papyrus, there was absolutely zero record of Atlantis anywhere on Earth. No Egyptian hieroglyph, no Babylonian tablet, and no Greek epic poem ever mentions its existence.
