Asia is a term used by Plato, particularly in connection with his description of Atlantis being greater than Libya and Asia together. Leaving aside the various arguments that the original passage meant that Atlantis was greater in ‘power’ rather than in geographical extent or that a change of a single letter in the Greek text would indicate a location ‘between’ Libya and Asia, we must again keep in mind that many words changed their meaning over the centuries. Edward Gibbon, the renowned 18th century English historian, noted that Greek and Roman writers used the term Asia to refer to Turkey, while others identify its use as a reference to ancient Lydia, a relatively small kingdom in western Turkey, rather than the vast continent it describes today. The same confusion is found in relation to Plato’s use of ‘Libya’ and also the ‘Pillars of Heracles’.
Furthermore, in Tim.24e, Plato informs us that Atlanteans were intent on the domination of all of the eastern Mediterranean including ‘Asia’, a clear indication that the Atlanteans arrived from the west.
