It thus appears that the very statement of Plato which has provoked the ridicule of scholars is in itself one of the corroborating features of his story. It is probable that the ships of the Atlanteans, when they returned after the tempest to look for their country, found the sea impassable from the masses of volcanic ashes and pumice. They returned terrified to the shores of Europe; and the shock inflicted by the destruction of Atlantis upon the civilization of the world probably led to one of those retrograde periods in the history of our race in which they lost all intercourse with the Western continent. The Preservation of a Record.--There is a singular coincidence in the stories of the Deluge in another particular. The legends of the Phoenicians, preserved by Sanchoniathon, tell us that Taautos, or Taut, was the inventor of the alphabet and of the art of writing. Now, we find in the Egyptian legends a passage of Manetho, in which Thoth (or Hermes Trismegistus), before the Deluge, inscribed on stelæ, or tablets, in hieroglyphics, or sacred characters, the principles of all knowledge. After the Deluge the second Thoth translated the contents of these stelæ into the vulgar tongue. Josephus tells us that "The patriarch Seth, in order that wisdom and astronomical knowledge should not perish, erected, in prevision of the double destruction by fire and water predicted by Adam, two columns, one of brick, the other of stone, on which this knowledge was engraved, and which existed in the Siriadic country." In the Chaldean legends the god Ea ordered Khasisatra to inscribe the divine learning, and the principles of all sciences, on tables of terra-cotta, and bury them, before the Deluge, "in the City of the Sun at Sippara." Berosus, in his version of the Chaldean flood, says: "The deity, Chronos, appeared to him (Xisuthros) in a vision, and warned him that, upon the 15th day of the month Doesius, there would be a flood by which mankind would be destroyed. He therefore enjoined him to write a history of the beginning, procedure, and conclusion of all things, and to bury it in the City of the Sun at Sippara, and to build a vessel," etc. The Hindoo Bhâgavata-Purâna tells us that the fish-god, who warned Satyravata of the coming of the Flood, directed him to place the sacred Scriptures in a safe place, "in order to preserve them from Hayagriva, a marine horse dwelling in the abyss." Are we to find the original of these legends in the following passage from Plato's history of Atlantis?
