The swallowing up of the island Atlantis from the ocean may, with as much reason, be considered historical, as fabulous. The shallowness of the Atlantic as far as the Canaries might be taken as a proof of this great event and the Canaries themselves for fragments of the island Atlantis. Plato tells us in his "_Timæus_," that the Egyptian priests, among whom he had travelled, had in their possession ancient registers which certified that island's going under water. Plato says that this catastrophe happened nine thousand years before his time. No one will believe this chronology on Plato's word only, but neither can any one adduce against it any physical proof, nor even a historical testimony from any profane writer. Pliny, in his third book, says that from time immemorial the people of the southern coasts of Spain believed that the sea had forced a passage between Calpe and Abila: _"Indigenæ columnas Herculis vocant, creduntque per fossas exclusa antea admisisse maria, et rerum naturæ mutasse faciem."_ An attentive traveller may convince himself by his own eyes that the Cyclades and the Sporades were once part of the continent of Greece, and especially that Sicily was once joined to Apulia. The two volcanos of Etna and Vesuvius having the same basis in the sea, the little gulf of Charybdis, the only deep part of that sea, the perfect resemblance of the two soils are incontrovertible testimonies. The floods of Deucalion and Ogyges are well known, and the fables founded upon this truth are still more the talk of all the West. The ancients have mentioned several deluges in Asia. The one spoken of by Berosus happened (as he tells us) in Chaldæa, about four thousand three, or four hundred years before the Christian era, and Asia was as much inundated with fables about this deluge as it was by the overflowings of the Tigris and Euphrates, and all the rivers that fall into the Euxine. It is true that such overflowings cannot cover the country with more than a few feet of water, but the consequent sterility, the washing away of houses, and the destruction of cattle are losses which it requires nearly a century to repair. We know how much they have cost Holland, more than the half of which has been lost since the year 1050. She is still obliged to maintain a daily conflict with the ever-threatening ocean. She has never employed so many soldiers in resisting her enemies as she employs laborers in continually defending her against the assaults of a sea always ready to swallow her. The road from Egypt to Phœnicia, along the borders of Lake Serbo, was once quite practicable, but it has long ceased to be so; it is now nothing but a quicksand, moistened by stagnant water. In short, a great portion of the earth would be no other than a vast poisonous marsh inhabited by monsters, but for the assiduous labor of the human race.
