These symbols form a universal language understood by Masons across the globe, transcending cultural and linguistic barriers. Each one is a key, unlocking a deeper understanding of oneself, one’s relationship with others, and one’s place in the universe. They are allegorical lessons veiled in familiar forms, encouraging introspection and contemplation.

This glossary aims to demystify some of the most common and significant symbols found within the Masonic tradition. It is an introduction for the curious and a refresher for the initiated, offering a glimpse into a system that uses ancient tools to build modern character. The journey into Masonic symbolism is a journey into the self, guided by timeless principles of truth, morality, and brotherly love.

What is the Purpose of Symbols in Freemasonry?
Why does Freemasonry rely so heavily on symbols instead of plain text? The answer lies in the power of allegory to convey complex ideas. A symbol can communicate layered meanings more effectively than a simple statement, engaging the mind on an intuitive level. It encourages a Mason to think for himself, to peel back the layers and discover personal meaning within a universal framework.
This method of teaching is as old as humanity itself. Ancient philosophies and religions have always used symbols to represent their core tenets. In Freemasonry, these symbols are primarily drawn from the tools of stonemasons, the architects of the ancient world. This connection is not accidental; the Craft presents itself as a system of ‘operative’ morality, where a man is the rough stone, and the Masonic teachings are the tools used to shape him into a perfect ashlar, a polished and perfected being fit for a place in the divine structure.
Ultimately, the purpose of these symbols is to ‘make good men better’. They are constant, tangible reminders of the virtues a Mason strives to embody: integrity, truth, equality, and charity. They are not objects of worship but focal points for meditation on one’s conduct and character.

What is the Most Recognizable Masonic Symbol?
The Square and Compasses, often seen with the letter ‘G’ at the center, is without a doubt the most famous emblem of Freemasonry. It is the visual signature of the Craft, displayed on rings, buildings, and documents. Its prevalence speaks to its central importance in Masonic philosophy, representing the core tenets that guide a Mason’s life.

What Do the Square and Compasses Represent?
Separately, the square and the compasses are functional tools of a builder. Together, they form a powerful allegory for moral and spiritual construction. The Square is an emblem of virtue. It is used by builders to test the accuracy of right angles and to ensure that a stone is ‘true’. For a Mason, it symbolizes the importance of squaring his actions by the square of virtue with all mankind.
It is a reminder to conduct oneself with honesty, integrity, and fairness. Just as a flawed stone can compromise an entire building, a life lived without moral rectitude is fundamentally unstable. The Square teaches a Mason to be a reliable and upright cornerstone of his community.
The Compasses are a tool used to draw circles, defining limits and boundaries. Symbolically, they represent the importance of self-restraint and circumscribing one’s passions. They remind a Mason to keep his desires within due bounds, avoiding excess and maintaining balance in all aspects of his life. It is about understanding one’s own limits and acting with wisdom and prudence. A deeper dive into freemason symbols meaning reveals how these tools guide a member’s entire moral compass.
The letter ‘G’ suspended in the center holds a dual significance. For many, it stands for God, or more inclusively, the Great Architect of the Universe. It places divinity at the center of a Mason’s life and work. It also stands for Geometry, the mathematical science upon which architecture and all of creation are believed to be based, reinforcing the link between the divine, the rational, and the constructive.

What Are the Working Tools of a Freemason?
Beyond the primary emblem, Freemasonry uses a host of other ‘working tools’, each with a specific moral lesson attached. These are introduced to a candidate as he progresses through the three initial degrees of the Craft: Entered Apprentice, Fellowcraft, and Master Mason. They serve as a curriculum for character development, with each tool building upon the lessons of the last.

What Are the Symbols of the Entered Apprentice Degree?
The first degree introduces the most fundamental tools for a new Mason, who is seen as a rough stone just beginning his transformation. The primary tools of this degree are the twenty-four-inch gauge and the common gavel. A more detailed list of masonic symbols explained can offer further insight into this initial stage.
The Twenty-Four-Inch Gauge is a simple ruler, representing the twenty-four hours of the day. It teaches a Mason about time management and the importance of dividing his day into distinct periods. These are typically for service to God and a distressed worthy brother, for his usual vocations, and for refreshment and sleep. It is a lesson in discipline, balance, and purpose.
The Common Gavel is a tool used by operative masons to break off the rough and superfluous parts of stones. In speculative Masonry, it represents the force of conscience. It is a symbol for divesting one’s heart and mind of the vices and impurities of life, thereby fitting oneself as a living stone for the spiritual building.

What Are the Symbols of the Fellowcraft Degree?
The second degree, or Fellowcraft degree, is focused on education and the intellectual pursuits of the liberal arts and sciences. Its tools reflect this shift from basic moral purification to intellectual and spiritual enlightenment. The principal tools are the Plumb, the Square, and the Level.
The Plumb is a weight suspended from a line, used to determine verticality. Symbolically, it is an emblem of rectitude of conduct. It reminds a Mason to walk uprightly and with integrity before God and man, never deviating from the line of virtue. It is about moral uprightness and being true to one’s principles.
The Level is a tool used to ascertain a horizontal plane. It is a powerful symbol of equality. It teaches that all men are created equal and meet upon the level, regardless of their station in life. Within the Lodge, worldly titles and distinctions are left at the door, and all brothers stand as equals.

What Are the Symbols of the Master Mason Degree?
The third degree is the culmination of ancient Craft Masonry, dealing with themes of mortality, fidelity, and the assurance of life after death. All the preceding tools of the Craft are presented to the Master Mason, but the most characteristic emblem of this degree is the Trowel. There is a whole wider world of freemason signs and symbols that a Master Mason is expected to understand.
The Trowel is a tool used to spread the cement that unites the individual stones of a building into a single, solid structure. For a Master Mason, it is the symbol of brotherly love and affection. It represents the work of spreading the ‘cement’ of fellowship and kindness that binds the members of the Fraternity into a strong and supportive community.

Are There Other Important Masonic Symbols?
The symbolic language of Freemasonry extends far beyond the working tools. Many other emblems appear in lodge rooms and on Masonic art, each carrying its own piece of the philosophical puzzle. These symbols often draw from ancient history, nature, and sacred geometry to convey their lessons.

What Does the All-Seeing Eye Mean?
The All-Seeing Eye, often depicted within a triangle, is one of the most famous and misunderstood Masonic symbols. It is not an emblem of sinister surveillance but a symbol of divine omniscience. It represents the eye of the Great Architect of the Universe, a constant reminder to a Mason that all his thoughts and actions are observed by a higher power. It encourages him to act with sincerity and virtue, even when no human eye is upon him. This is one of the most widely discussed masonic symbols explained in public forums.

Why is the Beehive a Masonic Symbol?
The Beehive is an emblem of industry and cooperation. It teaches Masons that, like bees in a hive, they should work together for the common good, each contributing his part to the welfare of the community. It is a lesson in the virtues of hard work, order, and the strength that comes from a well-organized and harmonious society. Many other freemason symbols are drawn from the natural world to teach these kinds of practical virtues.

What is the Significance of the Two Pillars?
Representing the two bronze pillars that stood at the entrance to King Solomon’s Temple, named Boaz and Jachin, these symbols are prominent in every Masonic lodge. Boaz is said to mean ‘in strength’ and Jachin ‘He will establish’. Together, they symbolize stability and the establishment of a firm foundation based on divine strength. They mark the entrance to the sacred space of the lodge, representing a point of passage from the profane outer world to the sanctified inner world of Masonic light and knowledge.

What Do the Sun, Moon, and Stars Represent?
The celestial bodies are important symbols representing the regularity and order of the universe, which the Lodge itself seeks to emulate. The Sun and Moon are often referred to as the ‘lesser lights’ of Freemasonry. The Sun is said to rule the day and the Moon to govern the night. Symbolically, the Sun represents the Master of the Lodge, and the Moon represents the Senior Warden, his second in command. The stars represent the multitude of brethren who populate the lodge, each a point of light in the Masonic firmament. The deeper masonic symbols meanings often relate to this cosmic and universal order.

What is the Meaning of the Anchor and Ark?
The Anchor and Ark are symbols of hope and safety. The Anchor, a classic emblem of security, represents a well-grounded hope and a well-spent life. It is a symbol that keeps a man steadfast during the trials and tribulations of his mortal existence. The Ark, referencing the biblical story of Noah’s Ark, is a symbol of a man’s journey over the turbulent seas of life. It represents the divine covenant and the promise of arriving safely in a harbor of peace and rest, provided one lives an upright and faithful life.

How Do These Symbols Connect to a Mason’s Journey?
The collection of Masonic symbols is not a random assortment of interesting pictures. They form a coherent and progressive system of education that mirrors a Mason’s personal journey. This journey is often described as the transformation of a ‘rough ashlar’ into a ‘perfect ashlar’.
A rough ashlar is an undressed, unpolished stone taken from the quarry. It represents a man in his natural state, ignorant of the refined principles of Masonry. Through the application of the working tools, the lessons of the degrees, and personal contemplation, he begins to smooth his own character. He chips away at his vices with the gavel and measures his progress with the square and compasses.
As he advances, he becomes a perfect ashlar, a smooth and finished stone ready to take its place in the spiritual temple. This is not a state of actual perfection but an ideal to strive for. It represents a man who has cultivated virtue, embraced knowledge, and lives in harmony with his brothers and the world. The symbols are the constant guides on this path, providing the blueprint for this internal construction project. They show a man what is required to be a mason in both name and character.
The beauty of this symbolic system is its timelessness. The tools of a stonemason are ancient, yet their moral applications are as relevant today as they were thousands of years ago. They provide a framework for self-discovery and moral development that helps a man navigate the complexities of modern life with a steady hand and a true heart.

Frequently Asked Questions

Can a non-Mason wear or display the Square and Compasses emblem?
While there are no laws prohibiting a non-member from wearing the emblem, it is widely considered inappropriate and disrespectful within the Masonic community. The Square and Compasses symbol represents a Mason’s personal commitment to the fraternity’s moral and ethical teachings, which he has solemnly promised to uphold. For someone who has not taken these obligations to display the emblem can be interpreted as making a false claim to membership and misrepresenting themselves.
This is distinct from a Mason’s family member, such as a spouse or child, wearing a piece of jewelry with the emblem as a sign of pride and connection, which is generally accepted. The core issue is one of intent and respect for the profound meaning the symbol holds for Freemasons. It is not a fashion accessory but a deeply personal and significant emblem of a member’s journey and character.

Why are the specific tools of a square and compasses so central to Masonic symbolism?
The centrality of the square and compasses stems directly from Freemasonry’s origins as a fraternity of operative stonemasons who built Europe’s great cathedrals. These two instruments were the most fundamental tools for a builder, used to test the accuracy of stones and to draw the plans for the structure. As Freemasonry evolved from an operative craft to a speculative, philosophical fraternity, it adopted these working tools as powerful allegorical symbols for moral self-improvement.
Just as an operative mason used the square to ensure his work was true, a speculative Mason uses it as a metaphor to square his actions by the principles of morality and virtue. Likewise, the compasses, once used to draw circles and lay out designs, now teach a Mason to circumscribe his desires and keep his passions within due bounds. These tools provide a tangible and constant reminder of the core lessons taught within the Lodge.

Are there other important Masonic symbols besides the Square and Compasses?
Yes, Freemasonry is rich with symbolism, and many other emblems are used to teach its moral and philosophical lessons. One of the most prominent is the All-Seeing Eye, often depicted within a triangle, which represents the omniscience of the Grand Architect of the Universe and the idea that a Mason’s thoughts and actions are always observed. Other key symbols include the plumb, level, and gavel, which are also working tools adopted for speculative meaning.
The plumb symbolizes uprightness of conduct, the level represents the equality of all men, and the gavel signifies the need to divest our hearts and minds of the vices of life. Each symbol serves as a piece of a larger allegorical system designed to guide a member’s personal development. While the Square and Compasses is the most recognized public-facing emblem, the wealth of other symbols is essential to the internal teachings of the fraternity.
