The Island of Meroë is the name given by some classical writers to the land bounded by the White Nile, Blue Nile and Atbara rivers. Meroë has over two hundred pyramids, built with their own distinctive style(d).
Thérêse Ghembaza submitted a paper to the 2008 Atlantis Conference, suggesting that Plato’s ‘Atlantida nesos’ was in fact this ‘island’ of Meroë. Her theory, which matches many, but not all, of the details provided by Plato, can now be read online(a)(b). For example, she does not attempt to explain Plato’s reference to the Atlanteans having control of the Western Mediterranean as far as Libya and Tyrrhenia.
