The Senior and Junior Wardens have miniature pillars on their pedestals, representing Jachin and Boaz (I Kings 7:21) respectively. These emblems did not exist in 1723 Masonry.
They first appeared circa 1760 in London Masonry. At that time, the Wardens carried them into the Lodge in the same manner as the Marshal carried his baton, under their left arms. None of the dozen exposés of Masonic ritual prior to Three Distinct Knocks, in 1760, mention the columns.
