What is the origin of Platos theory about the lost city of Atlantis?
In Plato’s book, Timaeus, a character named Kritias tells an account of Atlantis that has been in his family for generations. According to the character, the story was originally told to his ancestor, Solon, by a priest during Solon’s visit to Egypt. There had been a powerful empire located to the west of the “Pillars of Hercules” (what we now call the Straight of Gibraltar) on an island in the Atlantic Ocean. The nation there had been established by Poseidon, the God of the Sea. Poseidon fathered five sets of twins on the island. The firstborn, Atlas, had the continent and the surrounding ocean named for him. Poseidon divided the land into ten sections, each to be ruled by a son, or his heirs.
