Why Does Freemasonry Use Symbols?
The use of symbols is fundamental to the Masonic method of education. This tradition has its roots in the guilds of operative stonemasons who built the great cathedrals and castles of Europe. In an era when many were illiterate, symbols served as a universal language to convey complex architectural principles and craft secrets.
When Freemasonry evolved from an operative craft to a speculative or philosophical one, it retained this symbolic language. However, the tools and rules of stonemasonry were given new, moral meanings. A builder’s square was no longer just for ensuring a perfect right angle in stone; it became a tool for squaring one’s actions with the principles of virtue.
This symbolic approach makes learning a deeply personal experience. Instead of being told what to believe, a Mason is presented with a symbol and encouraged to reflect on its meaning. This process of discovery, veiled in allegory, allows the lessons to resonate more profoundly, guiding a member on their path of personal growth and enlightenment. Symbols are the vocabulary of this unique educational journey.

What Are the Most Common Masonic Symbols?
While there are hundreds of symbols used in Freemasonry, a few stand out as central to its teachings. These are the emblems you are most likely to encounter, each carrying layers of meaning that unfold as a Mason progresses through the degrees of the Craft.

What is the Meaning of the Square and Compasses?
This is undoubtedly the most recognized symbol of Freemasonry. It features a builder’s square and a pair of compasses, often with the letter ‘G’ in the center. Each component has a distinct and important meaning.
The Square is a symbol of morality, truth, and honesty. It reminds a Mason to ‘square’ his actions by the ‘square of virtue’ and to regulate his conduct according to Masonic principles. It represents the earthly, material world and our duties to our fellow man.
The Compasses, conversely, symbolize the spiritual and intellectual realm. They are used to draw circles, representing a boundary for self-restraint and a reminder to keep one’s passions within due bounds. The compasses teach a Mason to circumscribe his desires and live a balanced life.
The letter ‘G’ at the center has multiple interpretations. For many, it stands for God, or the Great Architect of the Universe, the supreme being to whom all Masons must profess a belief. It can also stand for Geometry, the mathematical science that was highly esteemed by ancient stonemasons and is seen as a pathway to understanding the divine order of the cosmos.

What Does the All-Seeing Eye Represent?
Often depicted within a triangle, the All-Seeing Eye, or Eye of Providence, is another prominent Masonic symbol. While it also appears in other contexts, including on the US dollar bill, in Freemasonry it holds a specific significance.
It symbolizes the omnipresence and watchfulness of the Great Architect of the Universe. It is a constant reminder that a Mason’s every thought and action is observed by a higher power, even when in secret. This is not a symbol of fearful surveillance but one of divine conscience and accountability.
The Eye encourages a Mason to act with integrity and truth, knowing that his deeds are always known. It represents the search for light and knowledge, as the eye is the organ of sight and perception. The triangle surrounding it, called a delta, often represents the deity and the perfection of divine wisdom.

What is the Significance of the Plumb and Level?
The Plumb and the Level are two more working tools of an operative mason that have been adopted for their symbolic lessons in speculative Masonry. They represent core tenets of Masonic character and social interaction.
The Plumb is a weighted tool used to determine a true vertical line. Symbolically, it represents rectitude of conduct, integrity, and the importance of living an upright life. It reminds a Mason to be just and true in all his dealings.
The Level is used to ascertain a true horizontal line. In Freemasonry, it is a powerful symbol of equality. It teaches that all men meet on the level, regardless of their wealth, social standing, or position outside the Lodge. Within the fraternity, all Brothers are considered equal. These concepts are a great starting point, but many more masonic symbols explained in further detail can illuminate the craft.

Why are the Sun, Moon, and Stars Important?
The celestial bodies play a significant role in Masonic symbolism, representing the order, regularity, and vastness of the universe as created by the Great Architect. They adorn the ceiling of many Masonic Lodges, creating a symbolic representation of the heavens.
The Sun represents the light of day and is a symbol of the Master of the Lodge, who is responsible for providing intellectual and spiritual light to the brethren. The Moon, which governs the night, symbolizes the Senior Warden, the Master’s second in command.
The stars represent the countless Masons scattered across the world and the divine beauty of the cosmos. They remind members of the vastness of creation and the importance of looking towards a higher source for guidance and inspiration. Unlocking the deeper masonic symbols meanings helps one appreciate the intricate connection between the Lodge and the universe itself.

What Do the Two Pillars, Boaz and Jachin, Symbolize?
At the entrance to every Masonic Lodge stand two symbolic pillars named Boaz and Jachin. These are representations of the two great bronze pillars that stood at the porch of King Solomon’s Temple, a central structure in Masonic allegory.
Boaz is typically translated as ‘in strength’, while Jachin means ‘he will establish’. Together, they
