Jason and the Argonauts and the quest for the Golden Fleece is recorded by Apollonius of Rhodes in his epic poem Argonautica. Although there are variants of some of the details in versions recounted by other authors, many researchers have felt that there was a kernel of truth in the story. Tim Severin was one of them and was inspired to retrace the voyage of the Argo in a replica of the ship, which led to the publication of The Jason Voyage. Decades later Dr Marcus Vaxevanopoulos of the Geology Department of the University of Thessaloniki in Greece expressed his belief that there is some reality behind the story of Jason and the Argonauts(a).
Although this has no direct bearing on the Atlantis story, when you combine these euhemeristic ideas along with Schliemann’s discovery of Troy after viewing Homer’s Iliad in a similar manner, it is understandable that many have sought the truth underlying Plato’s Atlantis narrative.
