Cosmology reflects the means available for studying the Cosmos and, in the past these included aspects of the cosmos requiring of human action. A knowledge of tuning theory was used to form harmonic cosmologies, which allied intermediary gods to necessary processes of human development within the cosmos.

one hundred years on from when it was drawn

Gurdjieff first presented his ideas to groups in pre-revolutionary Russia. Amongst his carefully chosen students it was the habit to reconstruct talks and diagrams as much as possible, an endeavour that gave us a textbook of Gurdjieff's ideas called In Search of the Miraculous (P.D. Ouspensky, 1950). This early form of the teaching was radically revised and extended by Gurdjieff, now as an author, during the 1920s, producing All and Everything whose part one was Beelzebub's Tales to his Grandson (G.I. Gurdjieff, 1950). Prior to drawing this diagram just after February 1917, Gurdjieff had been presenting ideas about transformation of energies, human and cosmic, using the musical theory surrounding the octave of eight notes. The Diagram of Everything Living was "still another system of classification... in an altogether different ratio of octaves... [that] leads us beyond the limits of what we call 'living beings' both higher [and lower] than living beings. It deals not with individuals but with classes in a very wide sense."
