If alchemy had a central story, it would be a love story. A King and a Queen, the Sun and the Moon, meet, undress, immerse themselves together in a bath, unite, die and are reborn as a new being. This is the coniunctio, the conjunction, the operation many authors consider the heart of the entire Work. Understanding it means understanding why alchemical texts speak of marriages so often.
What is united
The coniunctio is the union of two opposite principles. In the language of the treatises they take different names depending on the context:
| Active principle | Receptive principle |
|---|---|
| Sun | Moon |
| King | Queen |
| Sulphur | Mercury |
| Fixed | Volatile |
| Gold | Silver |
| Fire | Water |
These are not random lists: each pair describes the same relationship from a different angle. Sulphur is the principle that fixes and colours, mercury the one that flows and transforms. The Sun is hot and shines with its own light, the Moon is cold and reflective. The coniunctio brings them into a new relationship in which neither prevails.
The wedding as an image
Why marriage, of all things? Because it is the human experience in which two different realities remain themselves and together generate something neither could produce alone. Alchemists found in this image the most natural way to describe chemical union and, at the same time, a greater mystery.
Illustrations often show the sequence almost theatrically: the King and Queen join left hands, sometimes with a bird descending between them; then they enter a basin naked; finally they embrace. The water of the bath is the solvent that prepares them for union by removing their garments, that is, their outer impurities.
Death after the wedding
One detail always surprises those reading these sequences for the first time: after the union the couple dies. The two bodies lie in a tomb and putrefy. This is the nigredo that follows the conjunction. Authentic union is not a happy, motionless point of arrival but the beginning of a transformation that requires the end of earlier forms. Only after death does the soul return and the double being, the Rebis, is born.
A literary story
The theme of the alchemical wedding also had a literary life. At the beginning of the seventeenth century an allegorical tale appeared in Germany, the Chymical Wedding of Christian Rosenkreutz, in which the protagonist, by now an elderly man, is invited to a royal wedding that unfolds over seven days, amid trials, deaths and resurrections. The work belongs to the season of the Rosicrucian manifestos, but its plot draws directly on the images of the coniunctio.
The three degrees of union
A sixteenth-century alchemist, Gerhard Dorn, proposed a reading that became very influential in the twentieth century, above all thanks to the studies of Carl Gustav Jung. According to Dorn the conjunction takes place in three degrees:
- Mental union: the soul unites with the spirit, detaching itself from the rule of bodily passions. It is a moment of recollection and clarity.
- Union with the body: spirit and soul, now united, return to the body. Knowledge does not remain abstract but becomes embodied in concrete life.
- Union with the world: the being thus unified recognises itself as part of the original unity of the cosmos, which Dorn calls unus mundus, the one world.
This scheme shows clearly that the coniunctio is not a single act but a path. First you separate, then you reunite at a higher level.
The coniunctio in inner work
Read in an inner key, the conjunction concerns the relationship between different parts of oneself. Everyone carries a side that acts and a side that receives, a side that decides and a side that listens. Often these sides are at war or ignore each other. The coniunctio suggests three concrete steps:
- Recognise the two principles: give each a name, without judging which is better.
- Undress them: remove the masks each one presents, that is, automatic reactions and defences.
- Accept transformation: union changes both, and something of the old balance will have to die.
The same scheme also sheds light on human relationships: an authentic bond neither fuses two people into one nor leaves them separate, but transforms them both.
In short
- The coniunctio is the union of two opposite principles, such as Sun and Moon, sulphur and mercury.
- The texts portray it as a wedding between King and Queen, followed by death and rebirth.
- Gerhard Dorn described three degrees: mental union, union with the body, union with the world.
- Inwardly it invites you to integrate your polarities, accepting that union transforms them.
