Currently, we think of Alchemy as the precursor of chemistry, but it was a multidisciplinary practice that in its time had much in common with astrology, chemistry, medicine, and mysticism. References date to the 3rd century CE, in Egypt and Greece, with its most notable development in Alexandria, expanding toward China and central Europe; its peak expression in our continent was from the 13th to the 17th century. At first it was generally a chemical process in which the production of gold was sought, and it was not until its arrival in Europe that it transformed into a chemical-philosophical process. The church considered it a heretical practice, and the alchemists, to protect themselves, hid it under an amalgam of symbols, and to ensure their survival they carved them in stone, essentially in cathedrals, so that to the uninitiated it represented only an artisanal process. What truly interested the alchemists was the sequence of the process itself, for according to the doctrine of similar, the transformation of ordinary metals into gold was seen as a path to the Great Work, i.e., the passage of the spirit from ignorance to illumination. For this they referred to the possession of the Philosopher's Stone. This stone, for them, was not a physical object; it was a metaphor for the inner potential of the alchemist and the understanding of the purpose of the Work to achieve the final Robis. Grillot de Givry referred to the Philosopher's Stone: “You will not obtain the stone until you are perfect, and you will never be perfect if you seek the stone for the riches that accompany it.” The description of the process is too long and complex to summarize here, but the aim was to spiritually attain what they called Robis, or the primal being of creation before its fall, the Androgyne Adam that represented the original unity of masculine and feminine principles before the divine punishment. Human perfection can only be found in the divine image of its Creator. Adam and Eve would be nothing more than the result of a rupture or deification, where the primordial Adam became Adam and Eve. When Genesis tells us that Eve was created from Adam’s rib, it means that the human being was originally undifferentiated and that he constantly seeks this lost unity or endowment.
