That observation was probably made in Atlantis. The wide divergence of languages which is found to exist among the Atlanteans at the beginning of the Historical Period implies a vast lapse of time. The fact that the nations of the Old World remembered so little of Atlantis, except the colossal fact of its sudden and overwhelming destruction, would also seem to remove that event into a remote past. Herodotus tells us that he learned from the Egyptians that Hercules was one of their most ancient deities, and that he was one of the twelve produced from the eight gods, 17,000 years before the reign of Amasis. In short, I fail to see why this story of Plato, told as history, derived from the Egyptians, a people who, it is known, preserved most ancient records, and who were able to trace their existence back to a vast antiquity, should have been contemptuously set aside as a fable by Greeks, Romans, and the modern world. It can only be because our predecessors, with their limited knowledge of the geological history of the world, did not believe it possible that any large part of the earth's surface could have been thus suddenly swallowed up by the sea. Let us then first address ourselves to that question. CHAPTER IV. WAS SUCH A CATASTROPHE POSSIBLE? All that is needed to answer this question is to briefly refer to some of the facts revealed by the study of geology.
