The Location and Extent of the Lost Antediluvian Civilization of Atlantis

"For these histories tell of a mighty power which unprovoked made an expedition against the whole of Europe and Asia, and to which your city put an end. This power came forth out of the Atlantic Ocean, for in those days the Atlantic was navigable; and there was an island situated in front of the straits which are by you called the Pillars of Heracles; the island was larger than Libya and Asia put together, and was the way to other islands, and from these you might pass to the whole of the opposite continent which surrounded the true ocean; for this sea, which is within the Straits of Heracles, is only a harbor, having a narrow entrance, but that other is a real sea, and the surrounding land may be most truly called a boundless continent.
"Now in this island of Atlantis there was a great and wonderful empire, which had rule over the whole island and several others, and over parts of the continent, and, furthermore, the Atlanteans had subjected the parts of Libya within the columns of Heracles as far as Egypt, and of Europe as far as Tyrrhenia." - from Plato's Timaeus translated in RD, No. 2, 2006, p. 4
