Xavier Séguin (1949- ) is the French author of the Eden Saga website(a). We have encountered Séguin in Atlantipedia in relation to a number of subjects. Some of his ideas are, in my opinion, simply daft. For example, he suggests that megalithic dolmens and menhirs can generate vril energy, which can be used to expedite the maturing of wine(b)!
The most exotic suggestion regarding the Etruscans comes from Séguin, who has claimed that they share a common ancestry with the Yoruba of West Africa, as both originated in Atlantis(c), a concept ‘borrowed’ from Leo Frobenius. He also offered a most extreme theory regarding the Olmecs with the claim that they were astronauts. This idea was expressed(d) by Séguin, quoting US astronaut Gordon Cooper !
However, I considered Séguin to be totally unreliable when I found that he also quoted a fictional character, Professor Mortimer, from a work by the renowned writer, Edgar P. Jacobs, as supposedly uttered by a real scientist(e), in relation to the Pillars of Heracles.
