The Persian Wars are believed by some to have been the inspiration for the story of the Atlantean invasion described by Plato. Giuseppe Bartoli was apparently the first, in 1780, to make such a claim. Not too long afterwards Pierre-André Latreille supported the same idea.
This idea fails on two principal grounds, date and geography. Since the Persian War took place around 500-449 BC, this would make it subsequent to Solon’s visit to Egypt (570-526 BC) and Persia was east of Athens and Egypt, while the Atlanteans came from the west (Tim.25b & Crit.114c)! In fact, what Plato said was that the invasion came from the Atlantic Sea (pelagos). Although there is some disagreement about the location of this Atlantic Sea, all candidates proposed so far are west of both Athens and Egypt.
Since the Persian War took place over half a century after Solon’s death, in some ways, the suggestion that the Persian conflict inspired Plato’s Atlantis story, implies that Plato lied about Solon as the conduit for the account, which is completely at variance with the acceptance of Plato as a man of unquestioned integrity.
Apart from this date discrepancy, Jürgen Spanuth lists other divergences of the Persian Invasion theory from Plato’s text. Spanuth, together with many other authors, favours the Sea Peoples or as he puts it ‘the North Sea Peoples’, being the Atlanteans of Plato’s tale.
However, Pierre Vidal-Naquet, a prominent Atlantis sceptic, is adamant that the Persian Wars, with some modifications, parallel the Athenian war with Atlantis. William Babcock expressed a similar opinion in the early years of the 20th century. Acceptance of this view would rule Solon out as Plato’s source and undermine the credibility of the whole narrative.
Keep in mind that you can also find parallels between many of the European wars of the last few hundred years.
*In the mid-20th century, W. A. Heidel, an Atlantis sceptic, claimed(a) that an expeditionary naval force was sent by Darius in 515 BC under Scylax of Caryanda to explore the Indus River, which eventually encountered waters too shallow for his ships, was the inspiration behind Plato’s tale of unnavigable seas!*
He further claimed that Plato’s battle between Atlantis and Athens is a distortion of a war of invasion between the Persians and the Indians.
In late 2008 a new theory about Atlantis, was launched(a) by August Hunt that purports to link Atlantis with the Persian Empire with either Persepolis or Susa as the Atlantean capital described by Plato. He also offers the curious explanation for Plato’s 9,000 years for the age of Atlantis as being in reality a reference to the number of Athenians present at the Battle of Marathon! His short book is entitled Atalante and the Persian Empire
Jim Allen in a discussion of a number of ancient Persian cities, notes that some are circular and often had concentric walls, suggesting that they may have been the inspiration for Plato’s description of Atlantis’ capital city!
If the Persians were in fact the Atlanteans of Plato’s story, it seems rather odd that their invasion fleet, as recorded by Herodotus (Bk.7.89), included 200 Egyptian ships, while at the same time that Athens and Egypt were supposedly allies in opposition to Atlantis!
