Did Plato lie about the Egyptian origin of the Atlantis story when he composed his famous dialogs Timaeus and Critias? Classicists say he had good reasons to make up a persuasive tale to prove an important point about ancient Greek society and politics. This, so-called, Noble Lie Thesis is the lens through which scholars of ancient Greece look when they read what Plato has Socrates, Critias, Timaeus, and Hermocrates say to each other about divine law and human corruption, cosmos and soul, Atlantis and Athens, and the rise and fall at the hands of the gods of these once mighty city states. In this article, I put the Noble Lie Thesis to a test by examining Egyptian cosmogonical texts for substantial congruences with Plato’s dialogs.
