Hermetic Seal of Light (Quintessence)

This symbol, often referred to as the synthesis of alchemy or the Hermetic Seal, hearkens back to ancient Pythagorean philosophy, wherein the square, circle, the and the triangle are the emblems of the material body, the soul, and the spirit, the three elements believed to be necessary for alchemical transformation.

Alchemically, these are Mercury, Salt, and Sulfur. In Atalanta Fugiens, the alchemical text illustrated below, it is written, “Make of man and woman a circle; thence a square; thence a triangle; form a circle, and you will have the Philosopher’s Stone,” a hidden geometrical formula for creating an octave and a golden rectangle.
