Günter Bischoff (1950- ) has written (in German) a number of papers(a)(b) that strongly support Spanuth’s theory, which places Atlantis in the North Sea with the royal capital on a Helgoland larger than what we have today. He believes that its megalithic influence extended from Scandinavia and the British Isles on to North West France and southern Spain and the Western Mediterranean. He also includes central Europe and the Atlantic island groups in this loose confederation.
Bischoff also blames the Phaeton encounter for the destruction of the capital of Atlantis. Dale Drinnon has given us a translation(c) of Bischoff’s extensive paper on this matter. Further information is available on the Atlantisforschung.de website(d).
In 2016, Bischoff published his ideas in book form with a volume entitled Atlantis und sein Zentrum Althelgoland (Atlantis and its center Althelgoland).
Bischoff is due to give a lecture (in German) on his search for Atlantis, entitled Plato, Phaeton and Atlantis, on Saturday, July 8th, 2019, in Dresden(e).
