What is a square? In the context of Freemasonry, the square is a significant symbol that represents morality and the principles of right conduct. It is often described as an instrument used by stonemasons to ensure that stones are cut at right angles, which is essential for constructing stable structures. The square is also a symbol of the four elements and is associated with the foundation of eternal law. As noted in The Hidden Life in Freemasonry, the square is described as a geometrical figure with four equal sides and right angles, and it serves as a moral compass for Masons, guiding their actions and decisions to align with ethical standards.
