Bro. Fred Lomax explores the significance of the Square and Compasses as symbols of Freemasonry in his paper, "Why the Square and Compasses?" He references the Basic Principles for Grand Lodge Recognition from the Book of Constitutions of the United Grand Lodge of England, specifically Rule No. 6, which mandates the exhibition of the three Great Lights of Freemasonry during lodge activities. The Square and Compasses historically indicated meeting places for stonemasons and craftsmen, serving as a sign for those seeking work. The square represents "straight" masons, known for precision in stonework, while the compasses denote "arch" masons, recognized for their skill in creating arches. The paper also connects these symbols to the Coat of Arms of the Society of Free Masons, highlighting their historical and ceremonial significance, including their association with the Royal Arch and the Mark Degree. This understanding enriches the appreciation of Masonic traditions and the craftsmanship they symbolize.

Title Why the Square and Compasses?
Author Bro Fred Lomax – United Kingdom
The Basic Principles for Grand Lodge Recognition in the Book of Constitutions of the United
Grand Lodge of England states at No. 6 ‘That the three Great Li ghts of Freemasonry
(namely, the Volume of the Sacred Law, t he Square and the Compasses) shall always be
exhibited when the Grand Lodge or its subordinate Lodges are at work, the chief being the
Volume of the Sacred Law.’
Why did we choose the Square and Compasses as the outward signs of Freemasonry? Well
they probably stem from our medieval ances tors and it may not have been uncommon in the
middle ages to have an hostelry which displa yed as its sign the Square and the Compasses
to indicate that stonemasons an d other craftsmen were likely to meet there. And, as many
craftsmen travelled from place to place to fi nd work in those days, they might find suitable
employment by visiting such an establishment.
Incidentally, the sign of the square and compasses were also used by other craftsmen such
as carpenters but mainly by the stonemasons.
But how many of us know that the Square a nd the Compasses signified two different classes
of craftsman for which a long seven year apprenticeship had to be served before you
became elected a ‘fellow of the craft’?
The square in stonemasons terms relates to ‘s traight’ or ‘square masons’ the makers of
stone with straight edges which sit one on top of the other with remarkable precision as can
be seen in many of our splendid cathedrals and other notable buildings.
The compasses, on the other hand, denote the ‘round’ or ‘arch mason’ a different, and some
would say a superior, skill to produce the beaut iful arched naves of churches and doorways
at the entrance to many of our buildings(1)
On the Coat of Arms of the Society of the Free Masons, firs t granted by Edward IV, (1442-
1483) we see two supporters on either side of a shield, the one on the left-hand side, a
craftsman, had a square in his hand and he was wearing a jacket which was blue, whilst the
craftsman on the right is holding the compasses and his jacket was red(1)
Now perhaps you can see the connection betw een the Craft and the Royal Arch, but those
colours are of course also significant in the Mark Degree reflecting its connection too with the
Craft and the Royal Arch.
