This figure, often called Python, is an alchemical image of Mercurius before redemption—the inner dragon of the Work. It represents the soul in its divided, volatile state: part human, part beast, crowned with solar light it does not yet understand. The winged feet mark Mercurius as the mediator between worlds; the scaled body shows prima materia still bound to instinct and shadow; the three crowned heads signal the unresolved tension of Sun, Moon, and their coniunctio. This is the Exiled Prince at the beginning of the Royal Art: fallen into multiplicity, animated by desire and fear, surrounded by latent glory but lacking unity. In the Magnum Opus, Python is not an enemy to be slain but the very substance of transformation itself—the ego, the demiurgic force, the chaotic life-energy that must be purified, crucified, and transfigured. Only by descending into this Mercurial chaos does the Work begin. From this dragon will eventually arise the Stone, the Grail-bearing Knight, and the crowned King.
In the early stages of the journey, the Prince has not yet chosen the path, but the path has already begun to choose him. Upon the road he encounters a being that is not wholly other, yet not yet himself. It appears as a serpent with wings at its feet and three crowned heads burning with solar fire. This is Python Mercurius: the inner dragon of the Work, the soul in its divided, volatile state - part human, part beast, crowned with light it does not yet understand. The winged feet move swiftly between worlds but belongs fully to none. The three heads signal the unresolved tension of Sun, Moon, and Mercury This creature is the wanderer’s own self in a monstrous, primitive and differentiated stage. Here the he learns has his first encounter with the dragon that guards the treasure. From this volatile body and it’s strange and wild chaos will the Stone will be born and the Crown reclaimed. The Prince learns that the enemy is not without, but within his own mind and world. The serpent may later ascend but first it must be bound to the Cross of transformation, tempered by patience, and instructed by love. Until then it remains volatile, brilliant, and dangerous—poison and medicine in a single body. Only by remaining present to this chaos does the Great Work continue. The Prince does not flee the dragon. He studies its movement. He learns its language. He allows its fire to burn away illusion rather than consume the heart. From this mercurial storm the first true substance of the Work condenses.
“Python”. it represents a composite figure of Mercurius—specifically Mercurius in his chthonic, volatile, and transformative aspect.
It appears in multiple 16th–17th century alchemical manuscripts and printed emblem books, sometimes explicitly labeled Python, sometimes unnamed but clearly belonging to the same symbolic family.
In alchemy, Python signifies: The chthonic Mercurius The dragon aspect of the spirit The volatile soul-substance that both poisons and heals The serpent force that must be confronted, transformed, and integrated
This figure is a living hieroglyph of the spiritus mercurialis, shown in its pre-redeemed, chaotic, protean form.
The scaled torso indicates a serpentine, draconic nature. In alchemy, the dragon is not evil per se; it is prima materia in its raw, unconscious state.
The Dragon is th instinctual psychic energy, unconscious life force, and the raw soul prior to purification.
The human legs indicate that this force is already partially incarnated in the human being. This is Mercurius incarnatus—the spirit already walking in the world.
The winged sandals are unambiguous: this is Hermes / Mercury.
They signify: Speed, Volatility, Transcendence of fixed states, and The ability to move between worlds
This confirms that the entire figure is Mercurius, not a random monster.
The three serpentine necks rising from the body represent a triple manifestation of Mercurius.
Jung interprets this as a double quaternity condensed into a triadic form, where the fourth is implicit and unifying.
The three visible heads correspond to:
- Sol (gold, consciousness, spirit)
- Luna (silver, soul, reflection)
- Mercurius (the mediating coniunctio)
The solar faces above the heads indicate that even the dark, serpentine Mercurius contains latent solar light. The light is not yet integrated, but it crowns the chaos.
The small black cross attached to one solar head indicates Christianized alchemy.
It marks:
- the future crucifixion of Mercurius
- the necessity of sacrifice and death
- the transformation of Mercurius into Christ-Mercury
The iridescent wing with eye-like markings is the cauda pavonis, the Peacock’s Tail.
- the emergence of multiplicity
- the breaking of blackness
- the first appearance of color after nigredo
It appears between corruption and whitening. It is a threshold sign, not the end.
Its placement on the body shows that transformation is internal and ongoing, not yet stabilized.
This image is Mercurius as the inner dragon.
Carl Jung, "Psychology and Alchemy":
"PYTHON
The spiritus mercurialis and his transformations represented as a monstrous dragon. It is 2 quaternity, in which the fourth is at the same time the unity of the three, the unity being symbolized by the mystagogue Hermes. The three (above) are (left Lo right): Luna, Sol, and coniunctio Solis et Lune in Taurus, the House of Venus. Together they form Mercurius."
"Il Metamorfosi metallico et humano", c. 1564 by Giovanni Battista Nazari.
"Hear, sit, and understand what I say; and know that I will speak to you about that which many seek and few find, that which many call unknown, but few know. Listen, and you will understand how far you are from the truth. I am the Hen and the fierce Dragon that devours and recreates itself in time. By resurrecting through myself, I kill death and yet do not die. I nourish myself from my own body and heal myself by biting; the poison is sweet. Without me, life is impossible, but with me, life is not burdensome. I will show you the head of the Basilisk, which consumes its tail. From black, it is made red; from hatred, it becomes love; from poison, it becomes medicine. I am the eternal nature of this principle, and without me, the art of wisdom cannot be attained.
Many have tasted my bitterness, yet in it lies sweetness, because biting is the medicine. In the high mountains of the world, I find my rest and repose. In the plains of the earth and the streams of fire, I make my dwelling. In water, I slumber and am reborn. I give to the wise but deny the ignorant. Those who understand my mysteries will inherit wisdom. Those who do not, I leave to shadows.
Thus, the Hen becomes the Rooster, and the Rooster is united with the Hen. The Egg is born, but it is not just an egg. It is born of fire, nourished by wisdom, purified through its journey. This egg, our egg, holds the mystery of the wise. Once broken, it becomes a new life. What is inside cannot be known without effort; for the journey is long, and the key is knowledge.
After much suffering and effort, I saw the great wonders hidden within. There appeared two women sitting upon three columns. One wore white, the other saffron. Each held a crowned child at her breast—one crowned in gold, the other in silver. Their radiance outshone the Sun and the Moon, and I was struck with wonder.
These children grew before my eyes, rising with joy and wisdom. They surpassed all earthly things and illuminated the entire sky. My senses failed to comprehend such divine joy.
I continued on my journey, where I encountered salt brighter than crystal, glowing like the heavens. Within the salt, a figure of Hercules of Egypt appeared, holding a club and bow beneath an arch with the inscription:
"MULTI PER DIVERSA. HUC PERVENERVNT ITINERA."
("Many have reached this place through different paths.")
At the base, I saw the figure of Cerberus, the three-headed dog. At first calm, he grew fierce, forcing me to flee. My path led me to the summit of a high mountain, where I could go no further. There, I heard voices proclaim: "Through suffering, wisdom will be revealed."
Overcome with fatigue, I wept. My tears became a prayer for understanding. At that moment, a hieroglyphic tablet appeared, covered in symbols of animals and divine mysteries. I understood that only a purified soul could unlock their meaning. My journey continued inward, toward deeper truths.
At the final stage of my journey, I reached the royal halls of the King. The noble Maiden, who guided me, granted me entry into the celestial court. From the throne burst forth a radiant light, and at its base flowed a river of crystal-clear water, reflecting the brilliance of heaven.
The Maiden spoke softly: "This is the place where the faithful spirit finds its eternal home. Here begins the wisdom of the philosophers, those who wrote and composed their truths in perfect harmony. Soon, something of this will come to light."
With her words, I understood that this was the culmination of the journey. The mysteries of the philosophers had been revealed, and through trials and effort, the soul was enlightened.
IL FINE (THE END)"
I am the poison-dripping dragon, who is everywhere and can be cheaply had. That upon which I rest, and that which rests upon me,will be found within me by those who pursue their investigations in accordance with the rules of the Art. My water and fire destroy and put together; from my body you may extract the green lion and the red. But if you do not have exact knowledge of me, you will destroy your five senses with my fire. From my snout there comes a spreading poison that has brought death to many. Therefore you should skil- fully separate the coarse from the fine, if you do not wish to suffer utter poverty. I bestow on you the powers of the male and the fe- male, and also those of heaven and of earth. The mysteries of my art must be handled with courage and greatness of mind if you would conquer me by the power of fire, for already very many have come to grief, their riches and labour lost. I am the egg of nature, known only to the wise, who in piety and modesty bring forth from me the microcosm, which was prepared for mankind by Almighty God, but given only to the few, while the many long for it in vain, that they may do good to the poor with my treasure and not fasten their souls to the perishable gold. By the philosophers I am named mercurius; my spouse is the [philosophic] gold; I am the old dragon, found everywhere on the globe of the earth, father and mother,young and old, very strong and very weak, death and resurrection, visible and invisible, hard and soft; I descend into the earth and ascend to the heavens, I am the highest and the lowest, the lightest and the heaviest; often the order of nature is reversed in me, as re- gards colour, number, weight, and measure; I contain the light of nature; I am dark and light; I come forth from heaven and earth; I am known and yet do not exist at all by virtue of the sun's rays all colours shine in me, and all metals. I am the carbuncle of the sun, the most noble purified earth, through which you may change copper, iron, tin, and lead into gold. - Aurelia occulta, Jung, Alchemical Studies.
