Elemental Symbols in Triangles:
• These 4 triangles represent the 4 elements of fire, earth, water and air
• Fire is South, Air is East, Water is West and Earth is north
• These triangles are extracted portions of the 6-sided star
The Greeks were proposed that the universe was composed of 4 physical elements.
They also believed in a fifth element, which was the spirit. (The spirit element is also known as aether, or quintessence.)
In visual symbolism, the spirit is sometimes shown as circle. Other times it is shown as occupying the fifth point of a 5-pointed star with the other 4 elements.
These 4 triangular element symbols were created by alchemists when they created their symbolic language to record their efforts.
