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.
Here we have one section of a plate (see below). Do the first two rows show emblems of officers? The third row general Masonic symbols (perhaps referring to the first three degrees)? And the bottom row? If the image on the bottom right is the Master’s drawing board does the thing in the middle refer to the second degree and the mountain to the first? Do all images refer to different degrees?
