There are a few different interpretations of why the pyramid is such a powerful symbol of the Illuminati. One states that the Pyramid represents the command structure of the Illuminati organization, with the capstone symbolizing the Elite, with the most important members who are privy to all its secrets. The middle of the pyramid represents the various layers of society with the “masses” being at the bottom of the pyramid. IE. the base represents the uninitiated masses that the elite rule.
