What is Sacred Geometry? The ancient Greeks believed that it is the blueprint of all creation. Michael Hollenman, author of the “Intentional Living Series,” echoes that thought in “Intentional Geometry.” He writes, “Sacred Geometry is the vocabulary of creation. It is the grammar of life, the syntax of existence, the structure God uses to bring the invisible into visible form. To understand the universe, we must learn to understand the language it is written in.”
Throughout the ages, many others have repeated the same ideas. Greek mathematician Euclid said, “Where there is matter, there is geometry.” Galileo Galilei added later, “The universe is written in the language of mathematics and its characters are triangles, circles, and other geometric figures.” Sacred geometry is, therefore, the bridge between spirit and matter.
The principles of Sacred Geometry were first outlined by the Greek mathematician Pythagoras. He taught that mathematics and particularly geometry held the keys to the order and structure of the universe. Pythagoras directed his followers to pray with the Holy Tetractys (a triangle shaped by ten points). (Note 1)
The prayer of Pythagoras reflected his principles of Sacred Geometry. “Bless us, divine number, thou who generated gods and men! O holy, holy Tetractys, thou that containest the root and source of the eternally flowing creation! For the divine number begins with the profound, pure unity until it comes to the holy four; then it begets the mother of all, the all‑comprising, all‑bounding, the first‑born, the never‑swerving, the never‑tiring holy ten, the keyholder of all.”
The Greek philosopher Plato built upon Pythagoras’ concepts. He asserted that the knowledge of mathematics was key to developing an understanding of the universe. Plato wrote, “The Knowledge of which geometry aim is the knowledge of the eternal.” To that end, he developed five geometric solids that he believed formed the basis of the universe. For Plato, the Cube was earth, the Octahedron (air), the Tetrahedron (fire), the Icosahedron (water), and finally the Dodecahedron (the ether).
In the Thirteen Century, in Italy, Fibonacci (Leonardo of Pisa) developed the Fibonacci Sequence. As a mathematician, he studied nature and noted how the flowers and leaves grew. Based on his research, Fibonacci formulated how living things develop. The Fibonacci Sequence has each number as a total of the previous two numbers (0,1,1,2,3,5,8, 13….)
During the Italian Renaissance, Luca Pacioli published “The Divine Proportion” with Leonardo da Vinci providing the illustrations. Pacioli developed the Golden Ratio (Divine Proportion) based on the work of Vitruvius (Note 2), an ancient Roman architect. His Golden Ratio was the proportion of three lengths. In many life forms, the “Divine Proportion” appeared to be the most beautiful of all.
In his paper, “Sacred Spaces and Sacred Places,” Geoffrey Simmins, Associate Dean at the University of Calgary's Faculty of Arts, wrote that the term “Sacred Geometry” was first used in the High Middle Ages. Freemasons and other guilds used geometry for building the Gothic Cathedrals. For these guilds, geometry was sacred since their buildings became sermons in stone.
Sacred Geometry can be divided into the following:
• Two-dimensional forms: Circle, Square, Triangle, Cross, and Hexagon. From these flow the other forms like the Flower of Life.
• Three-dimensional forms: Platonic Solids, Metatron’s Cube, and Sphere.
• Higher Dimensional forms: Torus and Merkabah (Merkaba)
• Patterns of Nature: Fibonacci Sequence and Golden Ratio
Notes:
Note 1. The Tetractys had four rows of one, two, three, and four dots. Row one represents the Monad (Unity), row two: the Dyad (Power), row three: the Triad (Harmony) and row four: the Tetrad (Cosmos). Each row represents every geometric dimension. The Monad is the Point, Dyad (Line), Triad (Surface) and Tetrad (Solid).
Note 2. The Roman Vitruvius said that buildings should display strength, utility, and beauty. Da Vinci’s “Vitruvius Man” is based on Vitruvius’ theories.
