Mark Past Master's Collar Jewel

Making Your Mark: Some of you can, even now, remember people in your past (or present) who were illiterate and signed their name (made their mark)  with an "X".

Schools were for the wealthy.

Thus, operative Freemason symbols were taught to these stone masons (workers in stone) as a part of their obligation for the betterment of their craft.

Actual (operative) stone masons made their "mark" by inscribing their work with their symbol (or logo), just as artists and other craftsmen have "signed" their work throughout the centuries.  This "mark" symbolizes the uniqueness of the piece as well as the intent of the Master craftsman that each person who views it, be aware of its unique and personal craftsmanship.
