Riaan Booysen is a South African researcher who had written articles on a number of ancient mysteries that can be found on his website(a). Among his controversial ideas are that the Queen of Sheba, Nefertiti and Helen of Troy were a single person(b).
He offers a major paper on Atlantis, which he daringly identifies its location with Australia. Unlike other writers who have offered similar suggestions based on guesswork, Booysen offers a coherent thesis based on the geology of the South Pacific and early cartography.
