The Gospels can be understood and interpreted in the light of alchemical science. At first glance, they seem to recount the life of a man named Jesus, who was born in Palestine two thousand years ago, but in reality, they also describe alchemical processes throughout the various stages of his life, from his birth to his death and resurrection. Despite all the condemnations from the clergy, alchemy has profoundly permeated Christian mysticism and esotericism since the Middle Ages. And when one closely examines certain figures on the exterior as well as the interior of Notre-Dame de Paris or Notre-Dame de Chartres, one discovers that the builders of the cathedrals possessed knowledge of alchemy, of which the architecture and sculpture bear witness in many ways.
