W. S. Blacket’s Researches into the Lost Histories of America argues that the Atlantic Isle of Plato and Diodorus is the American hemisphere, not an island that sank in the ocean. The copy I used is London, Trübner & Co., Ludgate Hill, and Philadelphia, J. B. Lippincott & Co., 1884. He reads the Ptolemaic and Coptic zodiacs as old terrestrial maps, and he puts the signs that will not fit Europe, Africa, and Asia on America. Asiatic colonists crossed the Pacific. Their mixed descendants later crossed the Atlantic under names he takes from Greek, Phoenician, Hindoo, and Icelandic myth.
He keeps the war at about 9,000 years before Plato, and he rejects the submergence in the Timaeus because an island larger than Libya and Asia will not fit an Atlantic he computes at 4,000 miles (6437 kilometers) across. The only Lemuria in the book is the Roman festival of the Lemures, which he pairs with Peru. The book does not name Mu. The text is out of copyright. The quotations in the review are from this edition.
