Mesopotamia occupied part of modern Iraq. It was first (1535) suggested by G.F. Oviedo y Valdes as the location of Atlantis. After its inundation, he claims that the survivors fled to the Americas.
A recent article(c) by Marilyn Luongo also attempts to link Mesopotamia with Atlantis, beginning with locating the ‘Pillars of Heracles’ at the Strait of Hormuz and then using the highly controversial interpretation of ‘meizon’ to mean ‘between’ rather than ‘greater’ proceeds to argue that Mesopotamia is ‘between’ Asia and Libya.
Mesopotamia has recently been entered into the ‘Atlantis Stakes’ by Andreea Haktanir. Her website(a) has an extensive article that takes 14 chapters to conclude that Atlantis was Mesopotamia. Although I found her theory interesting, I was not convinced.
There is a website showing a huge number of maps relating to the various civilisations who existed in Mesopotamia over the millennia(b).
In July 2016 the most accurate timeline for the region was published following intensive research led by Cornell University archaeologist Sturt Manning(d). The data is now accurate back to the early second millennium BC and where estimates differed by up to 200 years, this has now been reduced to just 8 years.
Coincidentally, there is a region of Argentina called Mesopotamia that has also been identified as the original home of Atlantis.
