The Octahedron is one of the five Platonic solids. Platonic solids are each made from the same equilateral, equiangular polygons. Only five such shapes exist and are considered, in Sacred Geometry, to be geometrical ideals. The octahedron represents air.
Sacred Geometry symbols may have its roots in Ancient Greece, or even further back. It describes the belief that God, when creating the universe and everything in it, used a consistent kind of geometry or repeating regular shapes as the building blocks for existence.
Sacred Geometry, therefore, places meaning in geometric shapes, ratios and proportions. It ascribes to them a holy significance.
The shapes and ratios of Sacred Geometry can be found in the study of nature. Common examples include the nautilus shell, which forms a logarithmic spiral, and the regular hexagonal shapes found in beehives. Similar geometric ratios can be found in the human body, as evidenced in Leonardo Da Vinci’s famous Vitruvian Man sketching.
In Medieval Europe, churches and religious buildings were designed and constructed in keeping with the shapes and ratios believed to be divinely inspired. Much art of the period also made use of Sacred Geometry’s holy ratios and proportions. This was thought to bring the worshiper closer to God.
Sacred Geometry can also be found in Hindu teachings and many Hindu temples are laid out in accordance with geometric rules thought to have religious connotation. Islamic scriptures and holy sites also make significant use of geometric patterns.
The European Renaissance was when the principles of Sacred Geometry came to the fore, with a treatise written by Leon Battista Alberti, describing an idealized church building designed through use of Sacred Geometry. Modern-day visitors to Rome, in Italy, can see many examples of Sacred Geometry in the churches and temples from this period.
