This book is an attempt to interpret the meaning of those dumb, silent emblems that lie around us in the Lodge. I shall concentrate my attention of such objects as the Ashlars, the officers’ jewels, and so forth. The purpose of this works is to give a scientific explanation of the meaning of these symbols, based on the recognized laws of symbology and on the age-old interpretation of them.
