Emil Svensén (1850-1931) was a Swedish journalist who had a great interest in Atlantis. Thorwald C. Franke tracked down two publications(a)(b) in which Svensén offered his opinions on Atlantis.
He believed that Plato’s Atlantis was based on at least two historical realities – the invasions of the Sea Peoples and the eruption of Thera, although details of the events became distorted and eventually emerged as the narrative we now have.
