Continenza Angelo, was an Italian researcher, who, writing in Sykes’ Atlantean Research magazine in the middle of the 2oth century encapsulated the support of classical authors for the reality of Atlantis in the following terms;
“Hesiod spoke of Atlantis, as did Euripides, Diodorus Siculus and Seneca; Pliny says memories of Atlantis occur in the Labours of Hercules; Virgil comments on the Atlantean culture in the Georgies; Herodotus mentions it frequently; Pherecydes says ‘The people who lived near Mount Atlas said that they were descended from those who had accompanied Hercules on his travels.'” (a)
Pelasgians or Pelasgi is the term applied to early populations of the Aegean, prior to the Flood of Deucalion and subsequent arrival of the Hellenic peoples to the region. Pelasgian Greeks are recognised as having occupied Crete at the end of the 2nd millennium BC. It is unclear from classical sources(b) exactly what regions the Pelasgians occupied, not to mention when or where they originated.
Some writers such as Densusianu have postulated a Pelasgian Empire extending over a large stretch of central Europe.
Euripides stated that the Pelasgians were later called Danaans.
Spiro N. Konda believes that today’s Albanians are descendants of the Pelasgians and has written The Albanians and the Pelasgian Problem in support of this idea, unfortunately, it is in Albanian, but some of his arguments can be read, in English, online(a).
Oliver D. Smith in his book Atlantis in Greece identified “the Pelasgians with both the Atlanteans and prehistoric Athenians – as two regional tribes at war with each other”.
A more radical, highly speculative and quite incredible, alternative definition is offered by Marin, Minella and Schievenin[0972.471], which is that Pelasgians were refugees from their homeland in Antarctica after its catastrophic destruction. They claim that these refugees were also known as Titans, Tyrrhenians and Atlanteans, among other names! They further claim that anthropology calls them Cro-Magnon!
