Masonic Symbols Explained: A Complete Glossary of Meanings
From the mysterious All Seeing Eye adorning buildings and currency to the iconic Square and Compasses on rings and lodges, Masonic emblems are woven into the fabric of our culture. They spark curiosity, inspire debate, and for many, represent a hidden world of secrets and arcane knowledge. But the truth behind these powerful images is less about concealment and more about profound revelation. They are a rich, visual language designed to teach timeless lessons of morality, self-improvement, and spiritual truth.
Freemasonry, at its core, is a system of morality veiled in allegory and illustrated by symbols. It is one of the world’s oldest and largest fraternities, guiding men on a journey of personal development. The symbols are not secret codes for a global cabal; they are working tools for building a better self and a better world. Understanding these emblems is the first step to appreciating the deep philosophical traditions of the Craft. This complete guide to Freemasonry symbols will illuminate their meanings for the curious seeker.
The use of symbolism allows these lessons to transcend the barriers of language, culture, and time. Each emblem is a prompt for contemplation, a starting point for a conversation with oneself about virtue, integrity, and one’s place in the universe. It is a system that encourages personal interpretation, ensuring that the journey is unique for every Brother who walks the path.

Why Does Freemasonry Use So Many Symbols?
The origins of Masonic symbolism lie in the very real world of operative stonemasons, the master builders who constructed the magnificent cathedrals and castles of Europe. For these craftsmen, the tools of their trade were their livelihood. The square, level, plumb, and gavel were not abstract concepts; they were essential for creating perfectly aligned, stable, and beautiful structures. Their symbols were their trade secrets, a way to identify fellow craftsmen and protect their knowledge.
As Freemasonry evolved from an operative craft to a speculative one, these tools took on a new, allegorical meaning. A ‘speculative’ Mason is one who does not work with physical stone but uses the principles and tools of stonemasonry as metaphors for moral and spiritual development. The focus shifted from building physical temples to building a spiritual temple within one’s own heart. The tools of the stonemason became instruments for shaping one’s character.
This symbolic language is incredibly effective. A single image, like the Square and Compasses, can convey complex ideas about morality, restraint, and our relationship with both humanity and a higher power. It provides a universal vocabulary for Masons around the globe, creating a shared understanding that unites them. The symbols are not meant to be learned by rote but to be meditated upon, allowing each Mason to uncover layers of meaning relevant to his own life.

What Are the Most Common Masonic Symbols?
While the catalogue of Masonic symbols is vast, a core group of emblems appears most frequently. These are the foundational images of the Craft, introduced to a Mason as he progresses through the degrees. Each one serves as a cornerstone for the philosophical lessons taught within the Lodge. They are the alphabet of a language that speaks of integrity, truth, and the lifelong pursuit of light.

What is the Meaning of the Square and Compasses?
This is undoubtedly the most recognized emblem of Freemasonry. Even those entirely unfamiliar with the fraternity can often identify the interwoven Square and Compasses. Its meaning is profound and central to Masonic philosophy. It represents the intricate balance a man must find to live a virtuous and well-regulated life. Each component has its own distinct, yet complementary, significance.
The Square is an emblem of virtue and morality. Just as an operative mason uses a square to test the accuracy of angles and ensure a stone is true, a speculative Mason uses the principles of the square to ‘square his actions’ with all of mankind. It is a constant reminder to act with honesty, integrity, and fairness. It represents our duties to our fellow man and our responsibilities here on earth.
The Compasses symbolize the importance of self-restraint and circumspection. They are used to draw circles, defining boundaries and limits. For a Mason, this serves as a lesson to keep his passions and prejudices within due bounds. The Compasses represent our relationship with the divine, our spiritual nature, and the need to understand our own limits. The journey of understanding what is the freemason symbol often begins with this primary emblem.
Often, the letter ‘G’ is found in the center of the Square and Compasses. Its meaning is twofold and intentionally open to interpretation. For many, it stands for God, or more inclusively, the Grand Architect of the Universe. It can also stand for Geometry, which was considered the pinnacle of sciences and the logical foundation upon which the universe was built. The placement of ‘G’ in the center signifies that God and geometric principles should be at the center of a Mason’s life.

What Does the All Seeing Eye Represent?
The All Seeing Eye, or Eye of Providence, is another potent symbol that often causes misunderstanding. While it appears on the US dollar bill and in other cultural contexts, in Freemasonry its meaning is straightforward and deeply spiritual. It is a symbol of the watchful care of a supreme being, a reminder that our every thought and action is observed by the Grand Architect of the Universe.
This is not a symbol of sinister surveillance, but one of accountability and comfort. It encourages a Mason to live a life of truth and integrity, knowing that he is never truly alone and that his deeds do not go unnoticed. It pushes him to be his best self, not for the praise of others, but out of a sense of divine witness. The eye, often depicted within a triangle and surrounded by rays of light, symbolizes the omniscience and omnipresence of the divine.
It serves as a moral compass, a fixed point of reference in a complex world. When a Mason sees this symbol, he is reminded to look inward, to examine his own conscience, and to ensure his intentions are as pure as his actions. There are many great resources where Masonic symbols explained in detail can provide further context on this and other important emblems.

Why is the Masonic Apron So Important?
To an outsider, a simple white apron may seem like an odd piece of regalia. But to a Mason, it is his most important possession and a profound badge of honor. The Masonic apron is the first gift an Entered Apprentice receives, and it is a direct link to the operative stonemasons of old who wore leather aprons to protect their clothing from the dust and debris of their work.
In speculative Masonry, the apron’s meaning is transformed. The lambskin, or white leather, from which it is traditionally made, is a symbol of innocence and purity. By wearing it, a Mason is reminded that he should strive for a pure heart and a blameless life. It signifies that the work of a Mason is noble and that all Masons, regardless of their station in life, are equal within the lodge.
The act of wearing the apron distinguishes a Mason and signifies his dedication to the Craft. It is a constant, tangible reminder of his obligations and the virtues he has sworn to uphold. The journey of the free masons symbolic path is embodied in this simple, yet deeply meaningful, article of clothing.

What is the Significance of the Plumb, Level, and Square?
These three tools, known as the ‘Working Tools’ of a Fellowcraft Mason, are central to the Craft’s moral instruction. They are introduced as a set and represent the core tenets of a Mason’s conduct. Like the Square and Compasses, their meaning is derived directly from their practical use by operative stonemasons.
The Plumb is a weight suspended from a line, used to determine if a wall is vertically true. Symbolically, it represents uprightness of conduct. It reminds a Mason to live with integrity and rectitude, to be a pillar of moral strength in his community, and to judge others with fairness and impartiality. It is the tool of truth.
The Level is a tool used to ensure a surface is perfectly horizontal. As a Masonic symbol, it represents equality. It teaches that all men are created equal and meet on the level within the Lodge, regardless of wealth, status, or creed. It is a powerful reminder of humility and the shared human condition. A deeper dive into Freemason symbols often highlights the social and egalitarian lessons these tools teach.
The Square, as discussed earlier, is the tool for ensuring perfect right angles. It represents morality and virtue. Together, these three tools provide a complete guide for conduct: to act with morality towards all, to treat everyone with equality, and to live a life of unwavering integrity.

What Do the Two Pillars, Boaz and Jachin, Symbolize?
Standing at the entrance to every Masonic Lodge are representations of two great pillars, named Boaz and Jachin. These are references to the two bronze pillars that stood at the porch of King Solomon’s Temple, a structure of immense importance in Masonic lore. They represent the gateway from the profane, outer world to the sacred, inner space of the Lodge.
Boaz, the pillar on the left, is said to mean ‘in strength’. It symbolizes strength, stability, and the active, supportive power required to build anything of lasting value, including one’s own character. It represents the power and might needed to undertake the great work of self-improvement.
Jachin, the pillar on the right, is said to mean ‘He will establish’. It represents the principle of establishment, of creation, and of spiritual foundation. It symbolizes the divine will that establishes order in the universe and the moral law that provides a foundation for a just life. When a candidate enters the Lodge, he passes between these pillars, symbolically leaving the chaos of the world behind to enter a place of order, strength, and establishment. The story of the temple and its construction is a key part of unveiling the secrets behind the craft.

What is the Meaning of the Trowel?
The Trowel is one of the working tools of a Master Mason. In operative masonry, a trowel is used to apply the smooth cement that binds individual stones together into a single, solid wall. Its speculative meaning is a direct and beautiful allegory of this function. The Trowel symbolizes brotherly love and affection.
It is the tool used to spread the ‘cement of brotherly love’, which unites the members of the fraternity into one sacred band or society of friends and brothers. It teaches a Mason to smooth over conflict, to build bonds of fellowship, and to contribute to the harmony of the Lodge. While other tools are for shaping oneself, the Trowel is for building community and strengthening the bonds between Masons.

What Does the Gavel or Hiram’s Hammer Symbolize?
The Gavel is a symbol of authority, used by the Master of the Lodge to direct the proceedings and maintain order. It is an emblem of executive power. However, its deeper symbolic meaning relates to self-discipline and purification. The Gavel represents the force of conscience.
It is symbolically used to ‘divest our hearts and minds of all the vices and superfluities of life’. Just as a stonemason would use a hammer or mallet to chip away the rough, excess parts of a stone, a speculative Mason uses his conscience and willpower to remove his own imperfections. It is a tool for self-mastery, for breaking bad habits, and for refining one’s character. The way these simple tools are elevated to philosophical concepts is a core part of how Masonic symbols explained in Masonic education works.

What is the Rough and Perfect Ashlar?
The two ashlars are foundational symbols in Freemasonry, representing the beginning and the goal of the Masonic journey. The Rough Ashlar is a stone as it is taken from the quarry: crude, unfinished, and imperfect. It represents man in his natural state, ignorant and uncultivated.
The Perfect Ashlar is a stone that has been shaped, smoothed, and squared by the working tools of the craft. It is a perfect cube, ready to be fitted into the spiritual temple. It represents a man who, through Masonic education, self-discipline, and a virtuous life, has perfected his character. The transformation from the Rough to the Perfect Ashlar is the very purpose of speculative Freemasonry.

What Do Jacob’s Ladder and the Blazing Star Mean?
Jacob’s Ladder is a symbol drawn from the biblical story of Jacob’s dream of a ladder stretching from Earth to Heaven. In Masonry, it represents the connection between the terrestrial and the celestial. The rungs of the ladder are often said to represent a series of virtues, with the principal ones being Faith, Hope, and Charity. It symbolizes the path of spiritual ascent that a Mason should endeavor to climb throughout his life.
The Blazing Star is another symbol of divine light and guidance. It represents the sun, which illuminates the earth and brings life. It also symbolizes the light of reason and truth that should guide a Mason’s journey. It is a reminder of the divine spark within every individual, the source of inspiration and knowledge that, if followed, will lead him out of darkness and into light.

How Do Symbols Change Through the Masonic Degrees?
Freemasonry’s teachings are revealed progressively through a series of degrees. The symbols presented to a candidate evolve as he advances, building upon previous lessons. The three primary degrees of the ‘Blue Lodge’ are Entered Apprentice, Fellowcraft, and Master Mason.
In the first degree, the Entered Apprentice is introduced to foundational concepts. He is presented with the Rough Ashlar, representing his current state, and the tools needed to begin his work, such as the 24-inch gauge for dividing his time and the common gavel for divesting his vices. The focus is on purification and preparation.
The second degree, Fellowcraft, emphasizes intellectual development. The candidate is encouraged to study the liberal arts and sciences, symbolized by the winding staircase. The symbols of the Plumb, Level, and Square are given prominence, teaching the Fellowcraft how to apply principles of equality and integrity. This degree is about building knowledge upon the foundation of the first.
The third degree is the culmination of the Blue Lodge journey. A 3rd degree mason confronts the profound themes of mortality, fidelity, and the hope of immortality. The Trowel becomes a key symbol, emphasizing the importance of uniting the brotherhood. The central allegory of this degree imparts the final lessons of the Craft, preparing the Master Mason to be a leader and a teacher himself.

Are Masonic Symbols Secret?
This is perhaps the most persistent myth surrounding Freemasonry. The symbols themselves are not secret. A quick search online or a walk through a historic cemetery will reveal countless examples of the Square and Compasses, the All Seeing Eye, and other Masonic emblems. They are hidden in plain sight.
What is considered private to the fraternity is not the symbol itself, but the specific context in which it is presented during Masonic rituals. The ‘secret’ is the allegorical play or ceremony that gives the symbol its unique Masonic meaning. It is the shared experience of learning these lessons within the sacred space of the Lodge that is reserved for members.
Think of it like reading a great novel versus being part of the cast in its stage adaptation. Anyone can read the book, but the experience of embodying a character and participating in the performance is unique to the actors. Freemasonry’s symbols are the props and scenery; the ‘secrets’ are the personal journey and the shared experience of the play itself. The meaning is not handed to a Mason; it is discovered through participation, reflection, and a lifelong commitment to the principles they represent.
Ultimately, Masonic symbols are a beautiful and intricate system of education. They are a universal language that teaches some of life’s most important lessons: to be a person of integrity, to treat others with equality, to restrain one’s passions, to serve the community, and to constantly strive for more light. They are not signs of a conspiracy, but tools for personal and spiritual construction.

Frequently Asked Questions

What is the significance of the letter ‘G’ within the Square and Compasses?
The letter ‘G’ found in the center of the Square and Compasses emblem holds a dual significance within Freemasonry, representing core tenets of the craft. Its most common interpretation is that it stands for God, whom Masons refer to as the Grand Architect of the Universe. This acknowledges the centrality of a belief in a Supreme Being to the Masonic fraternity, serving as a constant reminder of faith and divine guidance.
Additionally, the ‘G’ also stands for Geometry, which is considered the noblest of sciences and the foundation upon which the structure of Freemasonry is built. This highlights the organization’s historical roots in the guilds of stonemasons and its emphasis on logic, reason, and learning as essential tools for self-improvement. The dual meaning elegantly intertwines the concepts of faith and reason, suggesting they are complementary paths to enlightenment.

Are Freemason symbols connected to the Illuminati or other secret societies?
While often linked in popular culture and conspiracy theories, Freemasonry and the historical Bavarian Illuminati were distinct and separate organizations. The Illuminati was a short-lived secret society founded in 1776 with specific political aims, and it was suppressed less than a decade later. Modern Freemasonry, on the other hand, is a much older and ongoing global fraternity focused on moral and spiritual development, not political revolution.
The symbols used by Freemasonry, such as the Square and Compasses, have well-documented allegorical meanings related to morality, truth, and personal growth for its members. The confusion largely stems from fictional works and theories that conflate various esoteric groups to create a more compelling narrative. There is no historical basis for the claim that Masonic symbols are secretly Illuminati symbols or that the two organizations are linked.

Can non-Masons use or display Masonic symbols?
Legally, anyone can display Masonic symbols as they are not typically trademarked in a way that restricts public use for personal expression. You might see the Square and Compasses on historical buildings, in art, or even sold as jewelry to the general public. There is no law preventing a non-Mason from wearing or using the emblem.
However, from an ethical and social standpoint, it is generally considered inappropriate and disrespectful for a non-member to wear a Masonic emblem. The symbol is intended to identify an individual as a member of the fraternity who has taken specific obligations and is committed to its principles. For a non-Mason to display it can be seen as misrepresenting themselves and claiming an honor they have not earned through the traditional Masonic journey.
