The Bavarian Order of the Illuminati used the pyramid symbol. The pyramid symbol was located on the floor of all Minerval assemblies. The scattered stones in front of the pyramid represented the Order’s unfinished work.

The young Illuminatus learned that the pyramid represented the Order itself.

The Minerval carpet features a painted pyramid with stones scattered in front and the letters ‘D’ and ‘P’ on each flank. The pyramid represents the Most Serene Order, aka the Illuminati, working together towards their common goal for the glory of the Great Architect. The letters D and P stand for Deo Proximo. (Nearest to God)
