Enrique Onffroy de Thoron was a French aristocrat whose family fled their homeland following the French Revolution(a). He was not Brazilian as claimed by Alexander Braghine. He travelled the world eventually settling in South America where he studied the language of the indigenous people of Peru. He later returned to France where he published the results of his research.
He believed that Atlantis was Phoenician and situated in America. According to Braghine, Onffroy de Thoron claimed that the Atlanteans along with the Andean Quichua tribe invaded Europe! Among his other strange conclusions (or should that be delusions?) was that the Carians of western Anatolia (Turkey) had populated the south-western shores of South America and that a Carian dynasty had once ruled in Quito (Ecuador)!
