axiom of maria
The Axiom of Maria Prophetissa — 'One becomes two, two becomes three, and out of the third comes the one as the fourth' — occupies a position of unusual centrality in the depth-psychological corpus, functioning simultaneously as a historical artifact of Hellenistic alchemy, a structural principle of the psyche, and a condensed formula for the individuation process. Jung himself identified it as 'one of the central axioms of alchemy' and returned to it persistently across his major works, from Psychology and Alchemy through Mysterium Coniunctionis and Aion. Its principal psychological valence concerns the tension between the triad and the quaternity: three functions of consciousness versus the recalcitrant, undifferentiated 'inferior' fourth, whose integration constitutes psychic wholeness. Edinger's commentary tradition elaborates this structural reading with characteristic clarity, while von Franz situates the axiom within the alchemical opus proper, tracing its operative function in texts attributed to Maria Prophetissa herself. The formula resonates outward into the problem of the Trinity, the God-image, and the symbolic arithmetic underlying mandalas, the I Ching, and Pythagorean tetraktys. Throughout the corpus, it marks the site where number symbolism, unconscious compensation, and the religious imagination converge — a locus where theology, alchemy, and analytic psychology discover their shared grammar.
we come to one of the central axioms of alchemy, namely the saying of Maria Prophetissa: 'One becomes two, two becomes three, and out of the third comes the one as the fourth.'
Jung formally introduces the axiom as a central alchemical principle, embedding it at the structural heart of his psychological interpretation of alchemy.

the 'axiom of Maria Prophetissa' (the Jewess or Copt), it appears in modern dreams, and is also found in psychology as the opposition between the functions of consciousness, three of which are fairly well differentiated, while the fourth, undifferentiated, 'inferior' function is undomesticated, unadapted, uncontrolled, and primitive.
Edinger applies the axiom directly to the typological structure of consciousness, mapping the one-two-three-four progression onto the differentiated functions and the recalcitrant inferior function.

this text is an allusion to the Axiom of Maria which concerns the whole matter of four and three. There are several versions of the Axiom of Maria; one goes like this: One becomes two, two becomes three, and out of the third comes the One as the fourth.
Edinger explicates multiple versions of the axiom and anchors it to the alchemical symbolism of the four elements as a number-symbolic meditation on the three-four problem.

The enigmatic axiom of Maria runs: '… from the third comes the one as the fourth' — which presumably means, when the third produces the fourth it at once produces unity.
Jung uses the axiom to interpret the fairy-tale motif of the mutilated quaternity, arguing that the fourth element in reunion with the triad constitutes psychic wholeness.
, The Archetypes and the Collective Unconscious, 1959thesis
This number symbolism refers to the axiom of Maria: 'One becomes Two, Two becomes Three, and out of the Third comes One as the Fourth.' This axiom runs through the whole of alchemy, and is not unconnected with Christian speculations regarding the Trinity.
Jung asserts the axiom's pervasive structuring role throughout alchemy and draws its explicit connection to Christian Trinitarian speculation.

He thus exemplifies that strange dilemma which is posed by the problem of three and four — the well-known axiom of Maria Prophetissa. There is a classical Hermes tetracephalus as well as the Hermes tricephalus.
Jung links the axiom directly to the figure of Mercurius, whose simultaneous tri- and quadriform nature embodies the three-four dilemma the axiom encodes.

Here we meet, at any rate in veiled form, the dilemma of three and four alluded to in the opening words of the Timaeus.
Jung identifies the three-four dilemma — the structural core of the axiom — as latent in Plato's Timaeus, tracing the problem back to ancient cosmological thought.

although Mercurius, in many texts, is stated to be trinus et unus, this does not prevent him from sharing very strongly the quaternity of the lapis, with which he is essentially identical. He thus exemplifies that strange dilemma which is posed by the problem of three and four.
Jung uses Mercurius's paradoxical tri-unity and quaternary nature as a living illustration of the axiom's structural tension between threeness and fourness.

Here is the number four, within whose bounds the number three, together with the number two combined into One, fulfils all things, which it does in miraculous wise.
This passage from Dorn, cited by Jung, articulates the numerical progression of the axiom — four containing three, two, and one — as the summit of alchemical knowledge.

Foliate gold is called 'sand' or 'washed earth' by Maria Prophetissa (Olympiodorus in Alch. grecs, III, iv).
Von Franz cites Maria Prophetissa as a historical alchemical authority on specific material operations, grounding her legendary status in the primary Greek alchemical texts.
