After Saint-Yves's death, portions of the writings he left behind were compiled by a group of his friends and devotees driven by Gérard Encausse alias Papus into a volume entitled l'Archéomètre. The title is Saint-Yves's name for a color-coded diagram he developed, showing symbolic correspondences between elements in astrology, music, alphabets, gematria, and other areas. This book has been translated into Spanish, and was translated into English for the first time in 2007 (publication pending).
