The term Continent has been applied arbitrarily by some commentators to Plato’s Atlantis, usually locating it in the Atlantic. In fact Plato never called Atlantis a continent, but instead consistently referred to it as an island. [Timaeus 24e, 25a, 25d  Critias 108e, 113c, 113d, 113e, 114a, 114b, 114e, 115b, 115e, 116a, 117c, 118b, 119c]

Modern geology has definitively demonstrated that no continental mass lies in the Atlantic and quite clearly the Mediterranean does not have room for a sunken continent .
