The Lost Symbol prominently features a small, portable sculpture of a pyramid as a plot device, which Dan Brown repeatedly refers to as a "Masonic pyramid." So, just about the time I sat down to write that Freemasons generally don't have pyramids in their lodges and their symbolism, I run across Lafite's Photostream collection taken inside of the Grand Orient of France's Paris temple (that sadly suffered major fire damage last week). These shots were taken more than two years ago, and it's a shame to know these lodge rooms have been seriously damaged. But lo! and behold, there sits a pyramid on what I presume to be the treasurer's desk (No, Mssr. Lafite would not grant me permission to post the photo here).
The Grand Orient is not recognized as regular by the majority of Masonic jurisdictions in the world, but if there is a GO Mason out there who could explain the significance of this pyramid sculpture in their lodge room, I'd love to hear it. It is possible it's nothing more than an elaborate alms box.
