In the fascinating, French publication, supposedly originally from 1765, called Mutus Liber Latomorum we find about 30 beautiful colour plates with often uncommon Masonic symbols. There is a suggestion that they refer to historical (proto Ancient and Accepted Scottish Rite?) degrees. The image above is early in the book, so it refers to a low/early degree?
