Cover of COSMIC FORCES OF MU by James Churchward (first published 1934) - According to Churchward, Mu was a lost continent in the Pacific Ocean, which was destroyed in a global cataclysm tens of thousands of years ago; Mu was the original home of mankind, and all subsequent civilizations descended from it. The Pacific islands and their inhabitants are supposed to be the last survivors of this primordial motherland. Churchward's Mu was a huge continent, which stretched from Micronesia in the West to Easter Island and Hawaii in the East. Churchward also believed in a literal mid-Atlantic Atlantis. He proposed a global network of huge gas-filled caverns which, if vented, could cause large areas of land to be submerged. - ?TopFoto / Fortean
