Alchemy

An art of transformation in matter, in medicine and, by figure, in the soul — in Roman Egypt, the Arabic and Latin worlds and China, and among the chymists and modern practitioners who inherited it.

ἓν τὸ πᾶν — the All is One. The motto written inside the ouroboros of the Chrysopoeia of Cleopatra (Codex Marcianus graecus 299, a tenth- or eleventh-century copy of a far older figure).

The Great Work

'Its father is the Sun, its mother the Moon; the wind carried it in its belly; its nurse is the earth.' The Emerald Tablet speaks of the work's product as something begotten and nursed rather than made, and the alchemists' philosophical tree grows from the same habit of speech: the vessel is a womb and a garden before it is a pot.

From Zosimos and the Arabic masters to Paracelsus and the Rosicrucian emblem books, and to the laboratory work the archive's own guests keep: alchemy as bench practice, as a theory of matter, and as a language of inner change, held distinct.

  1. Alchemy is not one thing. It is a long family of practices and symbolic languages concerned with transformation in matter, medicine, soul, body, cosmos, and divine knowledge.

  2. Some alchemies are explicitly laboratory based; others are medical, cosmological, devotional, initiatic, or contemplative.

  3. This page separates major lineages while showing why they repeatedly converge around purification, death and rebirth, conjunction, tincture, medicine, and the perfected body.

Magnum Opus

The colours of the Work

The texts describe the work as a run of colours in the vessel, and they do not agree on how many. The Greek authors name four — melanōsis, leukōsis, xanthōsis, iōsis. From the fifteenth or sixteenth century most Latin texts run three, black, white and red; some set a green or a peacock's tail of many colours after the black; and the operations behind the colours are counted differently again, twelve in Ripley's Compound and two in the maxim solve et coagula. The four below are the Greek scheme in Latin dress.

The sources describe work on matter in a vessel, in language saturated with death, marriage and rebirth, and some of them — Petrus Bonus about 1330, the Aurora consurgens — read the stone in Christian figures. Reading the colours as stages of the psyche is a later move: Atwood in 1850, Hitchcock in 1857, Silberer in 1914, Jung in 1944. It is productive, but it belongs to the reception of alchemy rather than to its texts.

    Nigredo

    Greek melanōsis

    Operation putrefactio† (putrefaction)

    The matter is reduced, darkened and allowed to rot. Nothing can be recombined that has not first been undone.

    Named by Jung (CW 12 §333) after the Greek authors; not a headword in LSJ, so it is given here only in transliteration.

    † One text's pairing; Ripley counts putrefaction as the fifth of twelve gates, after calcination, solution, separation and conjunction.

    Albedo

    The Whitening

    Greek leukōsis

    Operation ablutio† (washing)

    What survived the rot is washed. The lunar stage: the pure separated from the impure, and in many texts a white stone or tincture that perfects base metal to silver.

    As for melanōsis: Jung's form; LSJ has only the cognate λεύκανσις, 'a growing white', from Aristotle.

    The Yellowing

    Greek ξάνθωσις (xanthōsis)

    No operation is consistently paired with it.

    The yellowing. In the Greek sequence a stage in its own right; from the fifteenth or sixteenth century most Latin authors drop it and run three colours to the red. Kept here because the band draws the older Greek scheme, not because it is the commoner. No operation is consistently paired with it.

  4. 04 in this scheme

    Rubedo

    The Reddening

    Greek ἴωσις (iōsis)

    Operation fixatio† (fixation)

    Spirit and body are wedded and fixed: the red stone or tincture, which perfects base metal to gold and, the texts claim, can be multiplied and projected. That the work and the worker here become one is the modern spiritual reading, not the claim of the texts this band describes.

    LSJ glosses iōsis 'refinement' and 'the making of a tincture'; Jung renders it 'reddening'. The Latin red takes its place in the sequence rather than translating it.

    † One series' pairing, as for the other two; Ripley's twelve gates include no fixation, and his last after the red are multiplication and projection.

Four round vessels in a row, black, white, yellow and red, labelled with their Latin and Greek names; beneath them five rows show the same work counted differently: three colours in most Latin texts, a green or a peacock's tail after the black in some, twelve operations in Ripley, and two words in the maxim solve et coagula.

Metallic doctrine

Three principles, seven metals

Beneath the colour sequence sits the theory the colours were about: what bodies are made of, and which bodies the art recognised — and, beside it, the astral doctrine that set each metal under a planet, in pairings that took centuries to settle.

Sources Olympiodorus, commentary on Aristotle's Meteorologica, preserving Proclus' commentary on the Timaeus, on the metals (Stüve, CAG XII.2, 1900); Eng. in T. Taylor, The Fragments that Remain of the Lost Writings of Proclus (1825)Origen, Contra Celsum, VI.22H. C. Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

  • Sulphur

    sulphur

    The combustible, active principle: what burns, and what gives a body its colour and its particular nature. Male, hot, dry. In the older two-principle theory — first stated in the Arabic Secret of Creation and the Jabirian corpus, which recast Aristotle's two exhalations — sulphur and mercury are the two from which every metal is compounded.

    Sources Sirr al-khaliqa (The Secret of Creation), ascribed to Balinas, Arabic, by the early 9th centuryAristotle, Meteorologica, III.6, 378a15–b6

  • Mercury

    mercurius

    The volatile, fusible principle: what flows, vaporises and carries. Female, cold, moist. Philosophical mercury is expressly not common quicksilver; the texts belabour the point.

    Sources L. Abraham, A Dictionary of Alchemical Imagery, Cambridge, 1998, s.v. 'Mercurius'

  • Salt

    sal

    The fixed, incombustible principle: the ash that remains after burning, the ground of a body's solidity. As a third principle it is Paracelsus's addition (Opus paramirum, 1531) to a sulphur–mercury theory some seven centuries old; as a class of substances, salts were in al-Razi's laboratory long before.

    Sources Paracelsus, Opus paramirum, 1531, Book IAbu Bakr al-Razi, Kitab al-Asrar, classification of substances

Sulphur and mercury are the older pair; salt is Paracelsus’s third. The trio is a theory of composition, not a restatement of the four colours — the sources do not map one onto the other.

  1. Saturn

    Lead

    plumbum

    Soft, heavy, dull, quickly filmed over by air: the basest of the seven, and Saturn's. In the texts it is the metal of the nigredo and of melancholy; that it is 'the' starting matter of the work is a modern simplification, since every author names the first matter differently.

    Sources CRC Handbook of Chemistry and Physics, densities of the elementsTopic dossier, glossary, 'Prima materia'

  2. Jupiter

    Tin

    stannum

    Soft, white, low-melting; it cries audibly when bent, and alloyed with copper it makes bronze. Jupiter's in the settled list; Celsus gives tin to Aphrodite and Proclus to Hermes.

    Sources Origen, Contra Celsum, VI.22Olympiodorus, commentary on Aristotle's Meteorologica, preserving Proclus' commentary on the Timaeus, on the metals (Stüve, CAG XII.2, 1900); Eng. in T.

Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

  3. Mars

    Iron

    ferrum

    Hard and martial, and the only one of the seven that rusts red: its crocus martis, the 'saffron of Mars', makes it Mars's in colour as well as in temper. Celsus' ladder gives iron to Hermes.

    Sources Origen, Contra Celsum, VI.22H. C. Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

  4. Sol

    Gold

    aurum

    The fixed and incorruptible body: it does not tarnish and survives the fire. Quicksilver takes it into amalgam, and the aqua regia first described in the Latin Geber corpus about 1300 dissolves it. Not a stage of the work but its end.

    Sources pseudo-Geber, De inventione veritatis, c. 1300

  5. Venus

    Copper

    cuprum

    Warm-coloured, ductile, and green when it weathers; verdigris is its signature. The name runs back to aes cyprium, the metal of Cyprus — Venus's island.

    Sources Pliny the Elder, Natural History, XXXIV.2

  6. Mercury

    Quicksilver

    argentum vivum

    The only metal liquid at ordinary heat, and so the hinge between body and spirit. It came to Mercury late: Celsus gives Hermes iron and Proclus tin. The sources insist their philosophical mercury is not the apothecary's quicksilver.

    Sources Origen, Contra Celsum, VI.22Olympiodorus, commentary on Aristotle's Meteorologica, preserving Proclus' commentary on the Timaeus, on the metals (Stüve, CAG XII.2, 1900); Eng. in T.

Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

  7. Luna

    Silver

    argentum

    The second perfect metal: white, ductile, tarnishing but never rusting. Goal of the lesser work, argyropoeia, as gold is of chrysopoeia.

    Sources L. Abraham, A Dictionary of Alchemical Imagery, Cambridge, 1998, s.v. 'luna'

The pairing moved

Three lists, side by side and not joined: the planet–metal pairing was a tradition that moved. Cells where a metal differs from the settled list are washed in gold.

“A ladder with seven gates, and at its top an eighth gate.”

κλῖμαξ ἑπτάπυλος, ἐπὶ δ᾿ αὐτῇ πύλη ὀγδόη

Origen, Contra Celsum, VI.22 — Ed. Koetschau (1899). The ladder: lead–Kronos, tin–Aphrodite, bronze–Zeus, iron–Hermes, an alloy 'of mixed coinage'–Ares, silver–Moon, gold–Sun.

H. C. Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

A three-column table of planets and metals. Celsus' ladder: Kronos lead, Aphrodite tin, Zeus bronze, Hermes iron, Ares a mixed alloy, Moon silver, Sun gold. Proclus: Saturn lead, Jupiter electrum, Mars iron, Sun gold, Venus copper, Mercury tin, Moon silver. The settled list: Saturn lead, Jupiter tin, Mars iron, Sun gold, Venus copper, Mercury quicksilver, Moon silver.

The metal and the planet came to share one sign because the planets were held to rule the metals, and in Proclus to bring them to birth in the earth. The pairing itself moved: Celsus' ladder gives iron to Hermes and tin to Aphrodite, Proclus gives tin to Hermes and electrum to Zeus, and the familiar seven — quicksilver for Mercury, tin for Jupiter — settle only later.

Agrippa, De occulta philosophia libri tres (1533), I.23–29 (the things under the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury)

Metals were understood to form in the earth from two exhalations, Aristotle's vaporous and smoky, which Arabic theory recast as mercury and sulphur; the art's defenders claimed only to do quickly what nature did slowly. Avicenna, the great transmitter of that theory, denied the conclusion — the artisans of alchemy, he wrote, cannot change the species of metals — and the Latin schools argued over art and nature for four centuries. Metals isolated later (antimony, bismuth, zinc) never joined the seven: the scheme is cosmological, not empirical.

Saturn, then the Sun three places on, then the Moon, Mars, Mercury, Jupiter, Venus: Saturday to Friday. Celsus' ladder, read downward, gives the same order.

Chronology

How to read the chart

Each period is drawn to its extent on one shared axis, so a three-hundred-year epoch runs three times the length of a hundred-year one. The boundaries are conventional rather than exact: a bar marks where the surviving evidence sits, not the year a tradition began or stopped. The empty stretches are part of the record — but a gap here means this dossier holds nothing in that interval, not that nothing happened in it.

  1. 1st–4th century

    Not a void. In the Greek East the tradition continues as commentary — Synesius, the alchemical Olympiodorus, and Stephanos of Alexandria, who lectured on the sacred art at Constantinople under Heraclius. This dossier simply holds no entry for it.

    8th–10th century

    Not a void. Avicenna, the great transmitter of the theory that metals form from sulphur and mercury, denies in the Shifa' (c. 1020s) that the art can change one species of metal into another, and al-Tughra'i (d. 1121) writes the defence. In al-Andalus the Rutbat al-hakim on alchemy and its twin the Ghayat al-hakim (Picatrix) on astral magic, of contested date — tenth or eleventh century — set the two arts side by side. Latin Europe has craft recipes — Theophilus' On Divers Arts — but no alchemy until the translators arrive.

    Rosicrucian and spiritual readings

    Alchemical language is put to work on initiation and Christian regeneration — and, by the same people, at the bench. The word of the period is chymistry and it does not distinguish alchemy from chemistry: Starkey, writing as Eirenaeus Philalethes, is the most read alchemical author of the age and Boyle’s correspondent, and Newton leaves over a million words of alchemical manuscript.

  7. Gap · 1700 – 1850 · 150 yearsAbout this gap

    Not a void. The eighteenth century sorts chymistry into chemistry and alchemy — Étienne-François Geoffroy's paper on the frauds of the philosophers' stone (1722) is an early sign — while Hermetic alchemy flourishes in the Aurea catena Homeri (1723), among the Gold- und Rosenkreuzer from the 1750s, and in Dom Pernety's Dictionnaire mytho-hermétique (1758). Lavoisier's Traité élémentaire (1789) gives chemistry the elements that make transmutation a different question.

Figures

  1. Zosimos of Panopolis

    fl. c. 300

    One of the earliest major alchemical authors, blending craft procedure with visionary symbolism. Our only real source for several earlier practitioners.

  2. Maria the Jewess

    1st–3rd century

    Known chiefly through Zosimos, who cites her as a technical authority; Olympiodorus and the Arabic tradition cite her too. The tribikos and kerotakis are described as hers, and the water bath still carries her name — balneum Mariae, bain-marie.

  3. Ge Hong

    283–343

    The Baopuzi neipian, c. 317-320, is the fullest early account of Chinese external alchemy: elixirs, ingredients, and the transcendents who took them.

  4. Jabir ibn Hayyan tradition

    8th–10th century

    A vast Arabic corpus by many hands, influential for theories of balance, elixir, and metallic transformation. Not the author of the Latin Summa perfectionis.

  5. Abu Bakr al-Razi

    865–925

    Physician and alchemist, Latin Rhazes. His Kitab al-Asrar classifies substances, apparatus, and procedures with the allegory largely stripped out — the closest thing the tradition has to a laboratory manual. Not Fakhr al-Din al-Razi.

17 more figures (of 22)

  1. Zhang Boduan

    d. 1082

    The Wuzhen pian, 1075, founds the southern neidan lineage and is the point at which internal alchemy becomes a systematic discourse rather than a reading of older elixir texts.

  2. Paracelsus

    1493/94–1541

    Recast alchemy as medicine: the tria prima, the archeus, the doctrine of signatures, preparation over Galenic prescription. His influence is largely posthumous, through printings from the 1560s to the Huser edition of 1589-91.

  3. Michael Maier

    1568–1622

    Physician to Rudolf II and the most inventive of the Rosicrucian-era emblematists. Atalanta fugiens (Oppenheim, 1617) sets fifty emblems against fifty fugues for three voices.

  4. Thomas Vaughan

    1621–1666

    Wrote as Eugenius Philalethes: a Welsh writer on spirit, nature, and the first matter, and the publisher of the first English Fama and Confessio in 1652, with a preface of his own; whether the translation is his is uncertain. Routinely confused with Eirenaeus Philalethes, who was George Starkey.

  5. George Starkey

    1628–1665

    Harvard-trained, wrote as Eirenaeus Philalethes, and was the most widely read alchemical author of the later seventeenth century. Boyle's correspondent and Newton's source.

  6. Mary Anne Atwood

    1817–1910

    A Suggestive Inquiry into the Hermetic Mystery (1850) is the founding text of the reading that alchemy was never really about matter. Her father bought back and burned the edition; the argument survived him.

  7. Julius Evola

    1898–1974

    Italian Traditionalist. La tradizione ermetica (1931) reads alchemy as an initiatic path and a doctrine of inner sovereignty rather than a laboratory art.

  8. Avicenna (Ibn Sina)

    980–1037

    Gave the Latin world the theory that metals form in the earth from sulphur and mercury — and the denial that the art can change one species of metal into another. Attached to Aristotle's Meteorologica in Alfred of Sareshel's Latin, his verdict set the terms of the debate over art and nature.

  9. Roger Bacon

    c. 1220–c. 1292

    Distinguished a speculative alchemy, the theory of how things are generated from the elements, from an operative alchemy that makes better metals and medicines than nature does, and saw in the second a key to the prolongation of life.

  10. John of Rupescissa

    c. 1310–c. 1366

    Franciscan prophet who, imprisoned at Avignon, wrote On the Consideration of the Fifth Essence (c. 1351-52): distilled spirit of wine as a medicine — the hinge between alchemy and the distilled remedies Paracelsus inherited.

  11. George Ripley

    d. c. 1490

    Augustinian canon of Bridlington whose Compound of Alchemy (1471), dedicated to Edward IV, sets out the work as twelve gates from calcination to projection; the Ripley Scrolls that bear his name are later picture-texts.

  12. Heinrich Khunrath

    1560–1605

    Leipzig physician whose Amphitheatrum sapientiae aeternae (1595; 1609) engraves prayer and laboratory work in one hall, the oratory beside the furnace.

  13. Jan Baptist van Helmont

    1580–1644

    Flemish physician who made chymistry experimental — the willow-tree experiment, the word 'gas' — while reporting that he had seen projection with his own eyes; his Ortus medicinae (1648) shaped Starkey and Boyle.

  14. Robert Boyle

    1627–1691

    The Sceptical Chymist (1661) attacks both the Aristotelian elements and the Paracelsian principles, yet Boyle pursued transmutation all his life and in 1689 saw the old statute against 'multiplying' gold repealed.

  15. Isaac Newton

    1642/43–1727

    Spent some thirty years on alchemy and left over a million words of manuscript on it; Dobbs's Foundations of Newton's Alchemy (1975) made the papers a subject.

  16. Fulcanelli

    fl. 1926–1930

    Pseudonymous author of Le Mystère des cathédrales (1926), which reads Gothic sculpture as a hermetic book, and Les Demeures philosophales (1930); his identity is unsettled.

  17. Frater Albertus (Albert Riedel)

    1911–1984

    Founder of the Paracelsus Research Society at Salt Lake City and author of The Alchemist's Handbook (1960), the manual of the modern revival of plant spagyrics.

Source texts

  1. Physika kai mystika

    Greco-Egyptian, 1st-2nd c.

    The earliest substantial alchemical text, written under the name of Democritus by an author known only as pseudo-Democritus. Recipes for dyeing, gilding, and the imitation of gold and silver, framed as revealed secrets.

  2. Leiden Papyrus X and the Stockholm Papyrus

    Greco-Egyptian, 3rd-4th c.

    Two Greek recipe collections from Thebes. No theory and no allegory: craft procedures for dyeing, gilding, and imitating gems and precious metals. The bench floor under everything else on this list.

  3. Zosimos fragments

    Greco-Egyptian

    Visionary and technical treatises, surviving chiefly in the Byzantine Greek alchemical collection (Marcianus gr. 299, Paris gr. 2325 and 2327), with a substantial Syriac collection and a large Arabic tradition, the Muṣḥaf al-ṣuwar ('Book of Pictures') among it. The Authentic Memoirs are edited by Mertens (1995).

  4. Tabula smaragdina

    Arabic, by the 9th c.; Latin from the 12th

    The Emerald Tablet. Not by Hermes Trismegistus and with no recovered Greek original: its earliest known text sits inside the Arabic Sirr al-khaliqa ascribed to Balinas. Fourteen lines that European alchemy read as its whole programme. It does not contain the phrase solve et coagula.

  5. Turba Philosophorum

    Latin, 12th c., from a lost Arabic original

    A staged dialogue of pseudo-Presocratic philosophers, and the hinge on which Arabic alchemical vocabulary entered Latin Europe.

12 more source texts (of 17)

  1. Summa perfectionis

    Latin, later 13th c.

    Circulates under the name Geber and is not by Jabir ibn Hayyan; there is no Arabic original. Newman's 1991 critical edition argues for Paul of Taranto. The most rigorous corpuscular theory of matter the tradition produced.

  2. Rosarium philosophorum

    Latin, 15th c.; woodcuts printed 1550

    The compilation is fifteenth-century; the twenty woodcuts that made it famous — coniunctio, death, the returning soul — belong to the illustrated Frankfurt printing of 1550. Jung's 1946 commentary is on that image series, not on the medieval text.

  3. Aurora consurgens

    Latin, 15th c.

    Circulates under the name of Thomas Aquinas; the ascription is spurious. A commentary that reads the Song of Songs and the Sapiential books as alchemy, leaning on the Latin Senior. Von Franz's edition defends the Aquinas attribution; that defence has not been accepted.

  4. Chymische Hochzeit Christiani Rosencreutz

    Rosicrucian, 1616

    Published anonymously at Strasbourg. Johann Valentin Andreae later described it as a ludibrium — a piece of play. Read as initiatic allegory ever since, which may be the joke's most durable result.

  5. Zhouyi cantong qi

    Chinese alchemy

    Ascribed to Wei Boyang and traditionally dated 142 CE; the received text is layered and the ascription legendary. Waidan and neidan commentators read the same lines as external elixir and as internal refinement, and both readings have long lineages.

  6. Paracelsian corpus

    Medical alchemy

    A broad and unstable body of genuine, disputed, and outright spurious works, printed and reprinted from the 1560s. The pseudo-Paracelsian layer is large and was commercially useful.

  7. The Compound of Alchemy

    English, 1471

    George Ripley's verse treatise for Edward IV: the work as twelve gates — calcination, solution, separation, conjunction, putrefaction, congelation, cibation, sublimation, fermentation, exaltation, multiplication, projection.

  8. Amphitheatrum sapientiae aeternae

    German, 1595; enlarged 1609

    Heinrich Khunrath's engraved theosophy, whose fourth plate sets the oratory and the laboratory in one hall.

  9. Theatrum chemicum

    Latin anthology, Ursel 1602; Strasbourg 1613-1661

    The great collection of Latin alchemical treatises, six volumes in its final form; Jung's chief quarry.

  10. Musaeum hermeticum

    Latin anthology, Frankfurt 1625; enlarged 1678

    Shorter treatises with their emblems, Lambspring and Basil Valentine among them.

  11. Splendor solis

    German, illuminated manuscripts from 1531-32

    Twenty-two paintings of the work: kings, vessels and planetary triumphs. The London copy (Harley 3469) is dated 1582.

  12. Mutus liber

    French, La Rochelle, 1677

    The 'wordless book': fifteen plates of a man and woman at the furnace, with almost no text.

Glossary

The vocabulary this dossier uses, with the register each definition belongs to. Terms the archive has spoken about link into transcript search; terms treated more fully on this page point there instead.

Prima materiaOperative
The undifferentiated starting matter of the work. Named by dozens of cover-terms across the corpus and identified with a different substance by nearly every author; the concealment is deliberate. Search
Solve et coagulaOperative maxim
Dissolve and fix: shorthand for separation, purification, and renewed coagulation. A late crystallisation of a much older pair, ubiquitous in modern occultism, and not — despite frequent claims — a phrase from the Emerald Tablet. Search
NigredoColour stage
Blackening. Putrefaction: the matter is reduced and allowed to rot. Melanosis in the Greek sequence. The colours of the Work
AlbedoColour stage
Whitening. Ablution: what survived the rot is washed and the pure separated from the impure. Leukosis; the lunar stage, and in many texts the white tincture that transmutes to silver. The colours of the Work
CitrinitasColour stage
Yellowing. Xanthosis in the Greek four-colour sequence; most Latin texts drop it and run three colours to the red. The colours of the Work
11 more terms (of 16)
RubedoColour stage
Reddening. Fixation: body and spirit are wedded and the red stone or tincture completed, which perfects base metal to gold. Its place in the Greek sequence is held by iosis, which LSJ glosses 'refinement' and 'the making of a tincture'. The colours of the Work
SpagyricLaboratory / medical
A plant or mineral medicine prepared by separation, purification, and recombination. Paracelsus's coinage, from the Greek for to separate and to gather. Search
AlkahestLaboratory / contested
The universal solvent: a reagent supposed to reduce any body to its first matter without being altered itself. Paracelsian in origin and pursued as a literal laboratory goal, above all by van Helmont and by Starkey, who spent years on it and did not find it. Search
ChymistryHistoriographical
The period's own word, covering what later centuries split into alchemy and chemistry. Seventeenth-century authors did not recognise the division; it was made in the eighteenth and read backward onto them. Search
Cauda pavonisColour stage
The peacock's tail: a play of many colours on the matter as the black gives way, read as a sign that the work is going well. The colours of the Work
ViriditasColour stage
Greenness: in a few texts a stage between the black and the white; never general. Search
AthanorLaboratory
The alchemists' slow furnace, a tower fed from the side to keep an even heat for weeks. The name is the Arabic al-tannur, 'the oven'. Search
ProjectionOperative
The last operation: a little of the stone cast on molten base metal to transmute it. Ripley's twelfth gate. Search
Tria primaParacelsian
Sulphur, mercury and salt: Paracelsus's three principles — what burns, what fumes, and what remains as ash. Three principles, seven metals
CohobationLaboratory
Redistillation: the distillate poured back on its residue and distilled again, over and over — the 'fixing of the volatile' at the bench. Search
ChrysopoeiaGreek
Gold-making; with argyropoeia, silver-making, the Greek names for the two goals of the metallic art, as in the Chrysopoeia of Cleopatra. Search
