Giovanni Ugas is an archaeologist at the University of Cagliari, Sardinia, who has written extensively about the Shardana, their name, origin and language(c). The Shardana are usually counted as one of the Sea Peoples.
He has also touched on the subject of Atlantis, describing it as “a fabulous story with a political message, but this does not preclude the existence of a physical and historical substratum on which the myth is built. The task of tracing the shreds of history and geography of this story is fraught with pitfalls.”
* He also claims that the Mediterranean coast of southern Spain and France, along with the Italian peninsula was the ‘true continent‘ referred to by Plato (Timaeus 25a).*
