Masonic Symbols Explained: A Complete Glossary of Meanings
Freemasonry is often called a ‘peculiar system of morality, veiled in allegory and illustrated by symbols’. This description captures the very essence of the Craft. For centuries, its rich tapestry of emblems and icons has sparked curiosity, speculation, and a profound sense of wonder. These are not mere decorations; they are the visual language of a timeless tradition, each one a key to unlocking a deeper moral or philosophical lesson.
For those outside the fraternity, these symbols can seem mysterious or even cryptic. Yet, for the Mason, they are guideposts on a journey of personal development and enlightenment. They are tools for building a better self, just as an operative stonemason uses physical tools to build a cathedral. Understanding them is the first step toward appreciating the depth and beauty of the Masonic system.
This glossary is designed to demystify these powerful emblems for the general audience. We will explore the meanings behind the most common and significant symbols, shedding light on their historical context and moral applications. Prepare to journey into the rich world of Freemasonry symbols and discover the wisdom they have imparted to generations of seekers.

What Are the Foundational Symbols of a Masonic Lodge?
Every Masonic Lodge is built upon a symbolic foundation. Three great pillars of wisdom are said to support it, and three ‘Great Lights’ are essential for its operation. These form the core of Masonic symbolism.

What Are the Three Great Lights of Freemasonry?
The Three Great Lights are the Volume of the Sacred Law, the Square, and the Compasses. No Masonic Lodge can officially conduct its work without them being present and properly displayed. They are considered the spiritual and moral foundation of the Craft.
The Volume of the Sacred Law is the holy book appropriate to the faith of the members of a particular lodge. In many lodges throughout the Western world, this is the Holy Bible. However, it could be the Torah, the Quran, or other sacred texts. It represents a Mason’s belief in a Supreme Being and serves as the unerring standard of truth.
The Square is an emblem of morality. As an operative tool, it ensures that stones are cut to a perfect 90-degree angle, making them suitable for building. Symbolically, it reminds a Mason to ‘square’ his actions and live an upright life, treating all of humanity with fairness and honesty.
The Compasses symbolize the importance of self-restraint and discipline. Just as the tool is used to draw a circle and define its boundaries, a Mason is taught to circumscribe his desires and keep his passions within due bounds. Together, the Square and Compasses represent the balance between our moral duties to others and our personal responsibilities to ourselves.

What is the Meaning of the Letter G?
Often seen suspended between the points of the Square and Compasses, the letter ‘G’ holds profound significance. Its most common interpretation is that it stands for God, or the Great Architect of the Universe. It serves as a constant reminder of the divine presence that is central to a Mason’s life and work.
Additionally, the letter ‘G’ represents Geometry. In classical education, geometry was considered the noblest of sciences, through which the harmony and order of the cosmos could be understood. For Freemasons, it symbolizes the pursuit of knowledge and the application of reason and logic to understand the universe and one’s place within it.

What Are the Working Tools of a Freemason?
Freemasonry takes the tools of an operative stonemason and reapplies them as moral instruments for personal growth. These ‘working tools’ are presented to a candidate as he progresses through the degrees of the Craft, each with a unique lesson.

What Do the Gavel and Chisel Represent?
The Gavel and Chisel are the first tools a new Mason encounters. The Chisel represents the potential that exists within a person, refined by the benefits of education and perseverance. It is the mind’s ability to conceive of great things.
The Gavel, specifically a stonemason’s setting maul, represents the force of will and conscience. It is the instrument used to break off the rough and superfluous parts of a stone, symbolically divesting our hearts and minds of the vices and impurities of life. Together, they teach a Mason to shape his own character from a rough, imperfect state into a ‘perfect ashlar’ fit for the spiritual temple.

What Lessons Do the Plumb, Level, and Square Teach?
These three tools are often grouped together as symbols of rectitude and integrity. The Plumb is a weight suspended from a line, used to determine a true vertical. For a Mason, it symbolizes uprightness of character and the importance of walking justly before God and man. The history of such implements is a core part of understanding ancient Freemason symbols.
The Level is a tool for ascertaining a true horizontal plane. It is a powerful symbol of equality, reminding Masons that all men are created equal and share the same journey from birth to death, regardless of their station in life. It promotes humility and a sense of common humanity.
The Square, as discussed, is the emblem of morality and virtue. When these three tools are considered together, they provide a complete blueprint for ethical conduct. They instruct a Mason to be upright in his actions, equal in his dealings, and virtuous in his thoughts.

What is the Symbolism of the Trowel?
The Trowel is the tool used by operative masons to spread the cement that binds stones together into a single, solid structure. In speculative Masonry, it is the ultimate tool of a Master Mason, symbolizing brotherly love and affection.
Its purpose is to spread the ‘cement’ of unity and kindness that binds the members of the fraternity together into a peaceful and harmonious society. It teaches that while other tools are for shaping oneself, the Trowel is for building connections with others. The application of these lessons gives each emblem the deeper Freemason symbol meaning that Masons seek.

What Do the Architectural Symbols in a Lodge Mean?
A Masonic Lodge room is a symbolic representation of the universe, and specifically of King Solomon’s Temple. Its architectural features are rich with meaning.
