Originally published in French in 2014, Inner Traditions published an English translation in 2019. The author picks up after the suggestion of David Stevenson that second Shaw statute (a Masonic “old charge”) refers to the art of memory and that here we have a strong suggestion of very early Hermetic influences in (pre-)modern Freemasonry.
Another book that Jameux uses heavily is the famous Art of Memory of Frances Yates, first published in 1966. Yates makes a similar notes that Freemasonry may be such an art of memory, but leaves it to later investigators to look into the subject. Since Stevenson only raises the suggestion, Jameux thought it was time to combine both sources of information.
Jameux also uses a text of the French author Claudie Balavoine which is included in the appendices. Also an earlier version of Jameux’ text is added as appendix.
Knowing the two mentioned books, you may have an idea of the theory. Systems for remembering things have existed since the Greeks and have been used remarkably long. All the way up to the dawn of modern Freemasonry. As mentioned, Shaw appears to mention the art is in second set of statutes (around 1600).
The idea is not so much that Freemasonry includes the art of memory, but that Masonic symbolism actually is an art of memory. When you want to remember a speech, you can imagine a building and leave things in rooms that you have to remember for your speech and while speaking, walk through the imaginary building, a tracing board is something similar.
It is not so much that Jameux presents something new or extremely groundbreaking, but the book does make a very strong suggestion by combining the ideas found in two famous works. Definite proof? I doubt such a thing exists for a hypothesis such as this, but Jameux certainly strongly adds to the suggestion with some interesting details.
Unfortunately the book is not too well written. I actually found the initial essay (in the appendix) making the point better than the book. Be that as it may, Jameux certainly worked out a theory that I see a lot in better than I could.
