The rhombus represents fire and water coming together to form Earth associated with the 4 sides of this geometrical shape. It is the story of Genesis set in stone. It is an expression of divine art and wisdom realised in material form. It tells us about the cosmic origins of our planet and humanity.
The rhombus is like a source of inspiration that the pyramid builders could feel around themselves.
It could be a metaphor for both what we see in the layout of the pyramids as there are symmetries and patterns in the locations where they have been built. And it can be associated to the parallel layout of stars in constellations like Cancer.
The rhombus contains the Golden Ratio, universal harmony that is found in all things. It is as if the Bulgarian pyramid builders had captured cosmic harmony and set it in stone.
At the megalithic sites of Rozovets we find several granite stones in different locations that have been molded into the form of a rhombus.
At the Double Pyramid of Bania we found a rhombus shaped megalith with a skewer hole in the middle.
