The concept is replete throughout history and several religions, but I thought this was quite impressive.  It's relatively simple but still complex.  The Spirit and Soul combine to create the Body, a concept I have posted elsewhere.  Within the circles we see the circumpunct labled "Or", French for Gold.  The crescent is labled "argent" (Silver) and then Saturn is labled "Plumb" for lead.  The Plumb, or plumbum, is Latin for Lead which we derive from the Romans who invented a "plumbing" system.  A Plumb Rule is a tool used in ancient times by dangling a piece of lead from a string and comparing it to a wall or any perpendicular structure to ensure that it is properly upright.  Freemason's use this design as the badge of the Junior Warden in a Lodge.

Around the outside we see the French words for Air, Fire, Water and Earth - the four elements.  Notice that air, the spiritual soul, is at the top.  As we move down towards the earth, fire and water combine to create the body.  Fire is archetypically male and water is archetypically female, and the corporal manifestation of their combination creates earth (ame corporal, espirit corporal labeled along either side of the picture).
