Sacred Mysteries among the Mayas and the Quiches, 11,500 Years Ago is Augustus Le Plongeon’s essay of 1886, published in New York by Robert Macoy. He argues that the sacred mysteries, and through them modern Free Masonry, began among the Mayas in Mayax, the Yucatan peninsula and a Central American empire from Darien to Tehuantepec, and were carried to India, Chaldea, Egypt, and the Mediterranean about 11,500 years ago. The Quiche trials at Xibalba, the mound at Uxmal, and the family of king Can at Chichen and Uxmal are the evidence he reads from sculptures, the Popol Vuh, and the Troano manuscript.
He also says Plato’s Atlantis was a real island in the Atlantic, which he later calls Atlan, the third part of a western kingdom with North and South America. In this volume Queen Moo is a queen of Chichen, not a continent, and he does not name Mu or Lemuria. The mother-land phrase he prints is the Land of Kui.
