Archaeometer" is one of the few successful attempts to develop a universal alphabet model that explains the origin of the language of ancient cultures, using a wide range of material from the field of the history of religion. A famous follower of Fabre D'Olivet, the mentor of the French Martinists - Saint-Yves D'Alweidre worked on the book for fifteen years, receiving at different times six revelations from the divine country of Agarttha. His student Gerard Encoss (Papus), after the death of the teacher, published a treatise in Paris.
