Geometry was born to measure the earth, as its Greek name itself says. But human beings soon noticed that geometric shapes had something extraordinary about them: they were perfect, unchanging, the same everywhere. A circle drawn in Egypt was identical to a circle drawn in Greece. From this discovery came the idea that shapes are the language in which the order of the world expresses itself. This is what we now call sacred geometry.
The point and the circle
Every traditional geometric construction starts from two elements:
- the point, which has no dimension and represents the origin, unity, the principle from which everything arises;
- the circle, generated by rotating a distance around the point, which represents totality, the cosmos, what is complete.
The circle with a point at its centre is one of the oldest and most widespread symbols: in alchemy it stands for the sun and gold, in many traditions for the divine principle at the centre of creation.
The vesica piscis
If you draw two equal circles so that the centre of each lies on the circumference of the other, the overlapping area forms an almond shape: the vesica piscis, literally "fish bladder".
This figure has strong symbolic value:
- it represents the meeting of two worlds, the shared space born from the union of two distinct realities;
- it is the origin of the mandorla in medieval art, the oval frame surrounding the figure of Christ or the Virgin on portals and icons;
- it recalls the shape of the fish, one of the oldest Christian symbols;
- from its construction the equilateral triangle and other fundamental figures are easily derived.
The seed and the flower of life
By continuing to add equal circles according to the same rule, each centred on an intersection point of the previous ones, you obtain increasingly complex figures:
| Figure | Construction | Symbolic meaning |
|---|---|---|
| Vesica piscis | 2 circles | meeting, generation |
| Seed of life | 7 circles | the seven days of creation, the germ |
| Flower of life | 19 circles, often enclosed in a larger circle | order unfolding, interconnection |
The flower of life is a very ancient decorative motif, found on buildings, floors and objects in many cultures, from the Mediterranean to Asia. Its beauty lies in its regularity: every circle is equal to the others, and together they create a weave of petals in which no element dominates.
In symbolic reading the flower of life represents the unity of the many: many forms, a single rule.
The golden ratio
The golden ratio is a particular numerical proportion of about 1.618, obtained by dividing a segment into two parts so that the ratio of the whole to the larger part equals the ratio of the larger part to the smaller. This ratio is found in the regular pentagon and pentagram, and it recurs in some natural structures, such as the arrangement of seeds and leaves in certain plants.
In the Renaissance the mathematician Luca Pacioli devoted a treatise to it, De divina proportione, illustrated with drawings of geometric solids by Leonardo da Vinci. It is worth remembering that many modern claims about the golden ratio appearing "everywhere" are exaggerated: its fascination needs no forcing.
The Platonic solids
The Platonic solids are the five regular polyhedra, the only solid figures whose faces are identical regular polygons. In the dialogue Timaeus Plato associated them with the elements:
| Solid | Faces | Element |
|---|---|---|
| Tetrahedron | 4 triangles | fire |
| Octahedron | 8 triangles | air |
| Icosahedron | 20 triangles | water |
| Cube | 6 squares | earth |
| Dodecahedron | 12 pentagons | the cosmos as a whole |
It is one of the most fascinating attempts in the history of thought to unite mathematics and symbol: perfect forms as the hidden structure of matter.
The Studio's reading
For Studio Esoterico Cornelio sacred geometry is first of all a discipline of contemplation. Drawing a vesica piscis or a flower of life by hand, with compass and ruler, requires precision, patience and silence. It is an exercise that orders the mind as it orders the page.
A simple way to begin:
- get a compass, a pencil and a blank sheet of paper;
- draw a circle, then a second equal circle centred on the circumference of the first;
- continue adding circles on the intersection points until you complete the seed of life;
- look at the final figure and notice how it was born from a single repeated gesture.
In short
- Sacred geometry reads geometric shapes as the language of the world's order.
- The point and the circle represent origin and totality.
- The vesica piscis arises from two circles and symbolises meeting; the seed and flower of life develop from it.
- The golden ratio and the Platonic solids unite mathematics and symbol, but should be treated without exaggeration.
- Drawing these figures by hand is a practice of attention and inner order.
