Lyktonia is a strange land referred to in Samothracian legend, which recalls “that the dark-haired Poseidon grew angry at the father of Cronos and crushed Lyktonia with a blow of his golden trident.” This led to the disintegration of the land into separate islands.
Zhirov concluded that Lyktonia was the kingdom of Cronos and was swallowed by the ocean. He points out that that both Greek and Roman myths link Cronos (Roman Saturn) with a large island or continent far to the west. He also refers to the 19th century writer, Hieronymus Müller, who produced a well received German translation of Plato’s works and identified Lyktonia directly with Atlantis.
I would contend that a more rational explanation is that the legend refers to the inundation of what is now the Aegean Sea and had been dry land during the last Ice Age. Is it not more likely that a legend from Samothrace in the Northern Aegean would have developed out of experiences in its own region rather than any remote land to the relatively unknown west? This would fit in with the views of Kurt Lambeck who has gone a step further and suggested that this flooding of the Cyclades also included the demise of Atlantis.
