Translated as Freemasonry Returned to Its True Origin, or the Antiquity of Freemasonry Proved by the Explanation of Ancient and Modern Mysteries, this treatise by French author and scholar Alexandre Lenoir argues that Freemasonry originates in ancient mystery religions, drawing parallels between Masonic rituals and those of Egypt, Greece, and Rome. The work blends historical speculation with symbolic interpretation to legitimise Freemasonry’s antiquity and spiritual significance.
