In many English speaking countries, the Square and Compasses are depicted with the letter "G" in the center.3 The letter has multiple meanings, representing different words depending on the context in which it is discussed. The most common is that the "G" stands for God. Another is that it stands for Geometry, and is to remind Masons that Geometry and Freemasonry are synonymous terms described as being the "noblest of sciences", and "the basis upon which the superstructure of Freemasonry and everything in existence in the entire universe is erected. In this context, it can also stand for Great Architect of the Universe (a non-denominational reference to God)."4
The square and compasses have been used as a symbol by several organizations, sometimes with additional symbols:
