L. Frank Baum
William P. Phelon was a noted Theosophist, who, in 1903, together with his wife, Mira, wrote Our Story of Atlantis in which they predicted that the continent of Atlantis would reappear above the Atlantic waters, within the following century and stretch from the coast of Africa to the southern U.S.A. So far Atlantis has failed to surface.
Phelon claims that the ‘wisest scientists’ of his day supported the possibility of the existence of an island continent in the neighbourhood, if not directly over the great West Indian Archipelago. Phelon cites the now discredited Augustus Le Plongeon, who claimed that the inscriptions on the Mexican pyramid at Xochicalo were partly Egyptian. This foray into the word of fantasy may explain why it was Mr and Mrs Phelon who recommended the admission of L. Frank Baum(b), the author of The Wizard of Oz, into the Ramayana Theosophical Society in 1892.
It seems that Atlantis was mentioned in another of Baum’s many Oz books, Dorothy and the Wizard.
Phelon’s book was republished in 2009 but the original can also can be read online(a).
