The records inform us of the destruction by Athens of a singularly powerful army, an army which came from the Atlantic Ocean and which had the effrontery to invade Europe and Asia; for this sea was then navigable, and beyond the strait which you call the Pillars of Hercules there was an island larger than Libya and even Asia. From this island one could easily pass to other islands, and from them to the entire continent which surrounds the interior sea.... In the Island Atlantis reigned kings of amazing power. They had under their dominion the entire island, as well as several other islands and some parts of the continent. Besides, on the hither side of the strait, they were still reigning over Libya as far as Egypt and over Europe as far as the Tyrrhenian. All this power was once upon a time united in order by a single blow to subjugate our country, your own, and all the peoples living on the hither side of the strait. It was then that the strength and courage of Athens blazed forth. By the valor of her soldiers and their superiority in the military art, Athens was supreme among the Hellenes; but, the latter having been forced to abandon her, alone she braved the frightful danger, stopped the invasion, piled victory upon victory, preserved from slavery nations still free, and restored to complete independence all those who, like ourselves, live on this side of the Pillars of Hercules. Later, with great earthquakes and inundations, in a single day and one fatal night, all who had been warriors against you were swallowed up. The Island of Atlantis disappeared beneath the sea. Since that time the sea in these quarters has become unnavigable; vessels can not pass there because of the sands which extend over the site of the buried isle.[16] We have said that all fiction has some root in reality. Even a myth is commonly an attempted explanation of some mysterious natural phenomenon or distorted narrative of obscure, nearly forgotten happenings. Intentional fiction, try as it may, cannot keep quite clear of facts. We turn, then, to those salient features of the above excerpts which may in a measure stand for real past events or puzzling conditions supposed to continue. Beside the prehistoric grandeur and triumph of Athens, already dealt with, these are to be noted: the Atlantean invasion of the Mediterranean; the vastness of the outer island which sent forth these armies; its submergence; and the alleged continued obstruction to navigation in that quarter.
