Nestke & Riemer
Fritz Nestke & Thomas Riemer are the German authors of Atlantis – ein Kontinent tau (ch) t auf  published in 1989 six years before Rand & Rose Flem-Ath published their ‘Atlantis in the Antarctic’ theory in When the Sky Fell.*However, twenty years earlier Flavio Barbiero published a parallel theory , although I don’t know if Nestke & Reimer were aware of his book written in Italian!*
In support of their contention Nestke & Riemer have produced a ‘corrected’ translation of Timaeus 25d which they claim should read;
“… and Atlantis’ island as of disappeared even in its sea (removed from view) why it is now being impossible – because the slush of frozen sea even there is a very real obstacle – close gain access to the island” (p.170).
Like the Flem-Aths Nestke & Riemer also propose that a Pole Shift played a part in the destruction of Atlantis.
