Etymology **Coniunctio** (Latin: conjunction) is alchemy’s name for the **union of unlike substances**; psychologically, the union of opposites and the birth of new possibilities. Related: *hieros gamos*; *unio mystica*; *coincidentia oppositorum*; Philosophers’ Stone. Distinct from mere compromise or from [participation mystique](https://www.descentpress.com/index/participation-mystique/) (undifferentiated merger). --- ## 2\. Plain summary **Coniunctio** is the inner marriage—when opposed natures meet in a way that can make something new. Alchemy pictured it as chemical combination, as Christ and Church (Sol and Luna), as sacred marriage. Jung reads it as an [archetype](https://www.descentpress.com/index/archetype/) of psychic relationship between unconscious factors, projected onto kings and queens, sun and moon, pairs of every kind. The fruit is often imaged as a child of greater wholeness. Because it is archetypal, it carries both poles: rebirth and death, gain and loss. Bringing it to consciousness redeems what was unconscious; identifying with it ([inflation](https://www.descentpress.com/index/inflation/)) or dissolving into it ([participation mystique](https://www.descentpress.com/index/participation-mystique/)) misses the work. It belongs with [individuation](https://www.descentpress.com/index/individuation/), the [transcendent function](https://www.descentpress.com/index/transcendent-function/), and living [symbol](https://www.descentpress.com/index/symbol/)s. **Examples (exhaustive house list for this Index lemma — common coniunctio-related figures and motifs named across Jung’s essays and standard Jungian lexica; not a claim that Jung’s CW contains only these):** alchemical union of unlike substances; marrying of opposites; birth of a new element / child of wholeness; a priori image in mental history; Christian sponsus/sponsa (Christ–Church, Sol–Luna); pagan hieros-gamos; marital union of mystic with God; unio mystica; coincidentia / complexio oppositorum; unus mundus; Philosophers’ Stone; archetype of psychic relationship between unconscious factors; innumerable symbolic projections (man/woman, King/Queen, Sol/Luna, etc.); rebirth and transformation within the psyche; positive and negative poles (death/loss and rebirth); redemption of unconscious part; relation to [transcendent function](https://www.descentpress.com/index/transcendent-function/); [anima](https://www.descentpress.com/index/anima/)/[animus](https://www.descentpress.com/index/animus/) as pair; [self](https://www.descentpress.com/index/self/) as goal of union; [mandala](https://www.descentpress.com/index/mandala/) as ordered container; [active imagination](https://www.descentpress.com/index/active-imagination/) staging of the pair. --- ## 3\. Academic elucidation In analytical psychology the coniunctio is the **archetypal image of the union of opposites**, drawn from alchemy and applied to psychic processes of relationship, transformation, and the birth of a more whole attitude. Lexica stress both its centrality in the alchemical opus and its bipolarity (death as well as rebirth). Descent Press keeps Sharp and Samuels in §4 so lexicon paraphrase never silently becomes Jung’s voice --- ## 4\. Lexicon **Sharp (1991)** > Coniunctio. Literally, “conjunction,” used in alchemy to refer to chemical combinations; psychologically, it points to the union of opposites and the birth of new possibilities. … The coniunctio is an a priori image… two sources in alchemy, one Christian, the other pagan. The Christian source is… Christ and the Church, sponsus and sponsa… The pagan source is… the hieros-gamos… the marital union of the mystic with God. (Sharp, 1991) **Samuels, Shorter & Plaut (1986)** > Coniunctio … An alchemical symbol of a union of unlike substances; a marrying of the opposites in an intercourse which has as its fruition the birth of a new element… Jung… identified \[it\] as the central idea of alchemical process… an archetype of psychic functioning… capable of innumerable symbolic projections… when it occurs, death and loss as well as rebirth are inherent in the experience. (Samuels, Shorter, & Plaut, 1986, pp. **35–36**) --- ## 5\. CW concordance — sample, not exhaustive > The coniunctio is an a priori image that occupies a prominent place in the history of man's mental development. If we trace this idea back we find it has two sources in alchemy, one Christian, the other pagan. The Christian source is unmistakably the doctrine of Christ and the Church, sponsus and sponsa, where Christ takes the role of Sol and the Church that of Luna. The pagan source is on the one hand the hieros-gamos, on the other the marital union of the mystic with God. > (Jung, 1946/1966, CW 16, p. 169, ¶355) > The idea of the coniunctio served on the one hand to shed light on the mystery of chemical combination, while on the other it became the symbol of the unio mystica, since, as a mythologem, it expresses the archetype of the union of opposites. > (Jung, 1946/1966, CW 16, p. 169, ¶354) > The factors which come together in the coniunctio are conceived as opposites, either confronting one another in enmity or attracting one another in love. > (Jung, 1955–1956/1970, CW 14, p. 3, ¶1) > The coniunctio oppositorum in the guise of Sol and Luna, the royal brother-sister or mother-son pair, occupies such an important place in alchemy that sometimes the entire process takes the form of the hierosgamos and its mystic consequences. > (Jung, 1946/1966, CW 16, p. 200, ¶401) --- **See also:** [unus-mundus](https://www.descentpress.com/index/unus-mundus/); [participation mystique](https://www.descentpress.com/index/participation-mystique/); [transcendent function](https://www.descentpress.com/index/transcendent-function/); [symbol](https://www.descentpress.com/index/symbol/); [opposites](https://www.descentpress.com/index/opposites/); [anima](https://www.descentpress.com/index/anima/); [animus](https://www.descentpress.com/index/animus/); [self](https://www.descentpress.com/index/self/); [individuation](https://www.descentpress.com/index/individuation/); [mandala](https://www.descentpress.com/index/mandala/); [archetype](https://www.descentpress.com/index/archetype/); [active imagination](https://www.descentpress.com/index/active-imagination/); [inflation](https://www.descentpress.com/index/inflation/). ## References Jung, C.
