The Lost City of Atlantis is famous as Neptune’s city, full of mermaids and mermen. However Plato, a famous philosopher and mathematician in Classical Greece has made reference to the existence of Atlantis in two of his dialogues: Timaeus and Critias. Since Plato describes Atlantis as an active city, it is believed to have sunk to the bottom of the ocean, leaving much speculation as to whether the city truly exists or not.
