The square and compass-
The Square and Compass is single most identifiable symbol of Freemasonry. Duncan’s Masonic Monitor of 1866 states “The square, to square our actions; The compasses, to circumscribe and keep us within bounds with all mankind” But there is no set definition for symbol within Freemasonry. In the freemasonry, symbols are thought of as an onion with layers of meaning to be discovered the more one contemplates them. Richard Cassaro for example states “The square and circle shapes are related in Euclid’s 47th problem of “Squaring The Circle,” said to be the primary goal of the Masonic craft. Squaring the circle, however, does not in this case refer to a mathematical problem: it is a spiritual reference to man’s instinctive quest to harmonize our physical and spiritual natures.Since Antiquity, the square has represented the physical body. The circle, on the other hand, has always represented the soul.
The G in freemasonry is interchangeable with the Eye of Providence. It is used in English speaking countries because it is the initial for “The Great Architect of the Universe” Although some would say it is the initial for Geometry, the Generator or God. It is believed the G became widely used as a masonic symbol around the mid 1700’s in the United states and then spread to other English speaking countries.
The Ouroboros –
As humans have observed snakes shedding their skin for millennia; Thusly they have become a symbol of rebirth, transformation, immortality, healing, fertility, protection and a creative life force. The Ouroboros (a serpents biting on it’s own tail) is a symbol of eternity and continual renewal of life. These meaning span across space and time; Pythagoreans, Gnostics, Hindus, Buddhists, Native Americans and alchemist dating as far back as Egypt all revered the snake. The Chrysopoeia Ouroboros is one of the oldest known images of the Ouroboros and is said to be linked to the legendary Philosopher’s Stone. Carl Jung said ”The Ouroboros is a dramatic symbol for the integration and assimilation of the opposite, i.e. of the shadow. This ‘feed-back’ process is at the same time a symbol of immortality, since it is said of the Ouroboros that he slays himself and brings himself to life, fertilizes himself and gives birth to himself.”
