Prologue

The idea of vast cycles influencing human actions is not new. It has always seduced some researchers, philosophers and historians, including Plato, first and foremost. But to this day, no sufficiently convincing demonstration could be given. This book is not intended to provide a definitive proof, because the subject does not make it an easy task, but to present a broader vision of the models proposed by our predecessors in the study of cycles, historians Oswald Spengler and Arnold Toynbee, who focused on the movements of civilisations.

Historical cycles will lead us to the fundamental idea of this book: the existence of a vast cosmic cycle governing the human mind in its major orientations.

We will then try to show, with the help of our interpretive grid, and by carefully rereading some ancient texts, that this idea was already known in very remote times.
