"Delta

A triangle. The name of a piece of furniture in a Commandery of Nights Templar, which, being of a triangular form, derives its name from the Greek letter ~. delta. It is also the title given, in the French and Scottish Rites, to the luminous triangle which encloses the Ineffable Name (see Triangle). "- Mackey's Encyclopedia of Freemasonry

"The triangle, or Delta, is the mysterious figure of the Eternal. The three letters which you see, signify as follows:—G, at the top of the triangle, "the grand cause of the Masons": the S, at the left hand, the "submission to the same order": and the U, at the right hand, the "union that ought to reign among the brethren: which, altogether make but one body, or equal figure in all its parts." This is the triangle called "equilateral." The great letter G, placed in the centre of the triangle, signifies "Great Architect of the Universe," who is God; and in this ineffable name is found all the divine attributes. This letter being placed in the centre of the triangle, is for us to understand that every true Mason must have it profoundly in his heart. "– CAPTAIN WILLIAM MORGAN, The Mysteries of Freemasonry pg 171

"The sun being symbolized by an equilateral triangle, the three powers of the solar disc are said to be coequal. The three phases of the sun are called Will, Wisdom, and Action. Will is related to the principle of life, Wisdom to the principle of light, and Action, or Friction, to the principle of heat. By Will the heavens were created and the eternal life continued in supreme existence; by Action, friction, and striving, the earth was formed, and the physical universe molded by the Lords of the Fire Mist passed gradually from its molten condition into its present and more orderly state.”- Melchizedek & the Mystery of Fire by Manly P. Hall pg.11

"and the uniform symbol of this three-fold Deity was an equilateral triangle, the precise form occupied by our pillars of Wisdom, Strength and Beauty - Ancient Mystic Oriental Masonry By R. Swinburne Clymer pg. 157

"These three may be called thought, desire, and action. When purified and transmuted they are three glorious avenues through which may manifest the great life power of the three kings, the glowing builders of the Cosmic Lodge manifesting in this world as spiritual thought, constructive emotion, and useful daily labor in the various places and positions where we find ourselves while carrying on the Master's work. These three form the Flaming Triangle which glorifies every living Mason, but when crystallized and perverted they form a triangular prison through which the light cannot shine
and the Life is forced to languish in the dim darkness of despair, until man himself through his higher understanding liberates the energies and powers which are indeed the builders and glorifiers of
his Father's House."- The Lost Keys of Freemasonry or The Secret of Hiram Abiff by Manly P. Hall

"When we have united these three manifestations into a harmonious balance, we then have the flaming triangle. The ancients declared God, as the dot in the circle, to be unknowable, but said that he manifested through his three witnesses—the Father, the Son, and the Holy Spirit. Now the same is true with man. The part of God which is within each of us can manifest only through his three witnesses; the Father manifests through our thoughts, the Son through our emotions, and the Holy Spirit through our actions. When we balance our thoughts, our desires, and our actions, we have an equilateral triangle." - Anatomy of Man Manly P. Hall pg. 32

"The Delta, or mystical triangle, is generally surrounded by a circle of rays, called a "glory." When this glory is distinct from the figure, and surrounds it in the form of a circle (as in the example just given from Didron), it is then an emblem of God's eternal glory. When, as is most usual in the masonic symbol, the rays emanate from the centre of the triangle, and, as it were, enshroud it in their brilliancy, it is symbolic of the Divine Light. The perverted ideas of the pagans referred these rays of light to their
Sun-god and their Sabian worship. But the true masonic idea of this glory is, that it symbolizes that Eternal Light of Wisdom which surrounds the Supreme Architect as with a sea of glory, and from him, as a common centre, emanates to the universe of his creation, and to which the prophet Ezekiel alludes in his eloquent description of Jehovah: "And I saw as the color of amber, as the appearance of fire round about within it, from the appearance of his loins even upward, and from his loins even downward, I saw, as it were, the appearance of fire, and it had brightness round about."" - Albert G. Mackey, M.D., The Symbolism of Freemasonry

"Triangle

There is no symbol more important in its significance, more various in its application, or more generally diffused throughout the whole system of Freemasonry, than the triangle. An examination of it, therefore, cannot fail to be interesting to the Masonic student.

The equilateral triangle appears to have been adopted by nearly all the nations of antiquity as a symbol of the Deity, in some of his forms or emanations, and hence, probably, the prevailing influence of this symbol was carried into the Jewish system, where the yod within the triangle was made to represent the Tetragrammaton, or sacred name of God. The equilateral triangle, says Brother D. W. Nash (Freemasons Magazine iv, page 294),

"viewed in the light of the doctrines of those who gave it currency as a divine symbol, represents the Great First Cause, the Creator and Container of all things, as one and indivisible, manifesting Himself in an infinity of forms and attributes in this visible universe.

Among the Egyptians, the darkness through which the candidate for initiation was made to pass was symbolized by the trowel, an important Masonic implement, which, in their system of hieroglyphics, has the form of a triangle.

The equilateral triangle they considered as the most perfect of figures, and a representative of the great principle of animated existence, each of its sides referring to one of the three departments of creation, the animal, vegetable, and mineral.

The equilateral triangle is to be found scattered throughout the Masonic system. It forms in the Royal Arch the figure within which the jewels of the officers are suspended. It is in the Ineffable Degrees the sacred Delta, everywhere presenting itself as the symbol of the Grand Architect of the Universe.

In Ancient Craft Masonry, it is constantly exhibited as the element of important ceremonies. The seats of the principal officers are arranged in a triangular form, the three Lesser Lights have the same situation, and the Square and Compasses form, by their union on the greater light, two triangles meeting at their bases. In short, the equilateral triangle may be considered as one of the most constant forms of Masonic symbolism.

The right-angled triangle is another form of this figure which is deserving of attention. Among the Egyptians, it was the symbol of universal nature; the base representing Osiris, or the male principle;

the perpendicular, Isis, or the female principle; and

the hypotenuse, Horus, their son, or the product of the male and female principle.

This symbol was received by Pythagoras from the Egyptians during his long sojourn in that country, and with it he also learned the peculiar property it possessed, namely, that the sum of the squares of the two shorter sides is equal to the square of the longest side—symbolically expressed by the formula, that the product of Osiris and Isis is Horus. This figure has been adopted in the Third Degree of Freemasonry, and will be there recognized as the Forty-seventh Problem of Euclid (see Geometry, Circle, Square, and Forty-seventh Problem)."- Mackey's Encyclopedia of Freemasonry


"Life may be represented by a Triangle, at the apex of
which is God. Of this triangle the two sides are formed by two streams, the one flowing outwards, the other upwards. The base may be taken to represent the material plane." - The Philosophy Of Fire By R. Swinburne Clymer pg. 55

"The shape of the Pyramid itself has one of the deepest meanings to the Initiates. A Pyramid, the triangular form of it, signifies fire, and the cubical form the earth visited by fire. Fire in turn signifies Love, God, the Fatherhood of God." - Ancient Masonry Oriental Masonry By R. Swinburne Clymer pg. 30
