Hermeticism
The Greek, Latin, Coptic and Arabic writings ascribed to Hermes Trismegistus, and the traditions that read them.
The Hermetic writings are not one book but a library assembled across centuries, attributed to a teacher who may never have lived. What they share is a conviction that the cosmos is intelligible, and that the mind reading it is of the same order as the thing read.
Orientation
Reading Hermeticism

The Krater
Corpus Hermeticum IV: God filled a great basin with Nous, sent it down, and had a herald cry to the hearts of men — immerse yourself, if you can. Baptism not in water but in mind, proclaimed to every heart and received by those who understood the proclamation.
From the Greco-Egyptian treatises and the technical Hermetica to Ficino's Florence, Casaubon's redating and the Kybalion — the archive's Hermetic conversations, kept apart from the modern principles that borrowed the name.
Hermeticism names the traditions descending from Greek writings attributed to Hermes Trismegistus — the thrice-greatest — composed mainly in Roman Egypt between the first and third centuries CE, where the scribe-god Thoth had long been read as Hermes.
The corpus is usually divided in two, after Festugière: philosophical Hermetica on God, cosmos, mind, and rebirth, and technical Hermetica of astrology, medicine, alchemy, and talismans — the astrological strand older than any philosophical treatise. Garth Fowden showed that the two shade into each other: one Greco-Egyptian milieu, one cosmos of sympathies, and a path that leads from practical knowledge of the world to knowledge of God.
This page keeps the ancient corpus, the Arabic transmission, the Renaissance revival, and the modern receptions distinct, because most confusions about 'Hermeticism' come from silently blending them into one continuous institution.

Corpus Hermeticum XIII
The ten and the twelve
The thirteenth treatise of the Corpus is a rite written as a dialogue. Tat reminds his father of a promise: Hermes had told him that no one can be saved before rebirth, and that he would teach it when Tat was ready to become a stranger to the world. What follows is not an argument but an initiation performed on the page — instruction, silence, the arrival of the powers, a hymn.
At its centre is a piece of arithmetic. Twelve tormentors of matter hold the embodied self, ignorance first and malice last; ten powers of God drive them out — knowledge, joy, self-control, steadfastness, justice, sharing, truth, the good, life and light. Seven are matched one to one; with truth the good is filled up and the rest fly off together. The decad, the treatise says, is what gives birth to soul.
Sources Corpus Hermeticum XIII, 'Hermes to his son Tat: a secret discourse on the mountain, on rebirth', 1Corpus Hermeticum XIII, 'Hermes to his son Tat: a secret discourse on the mountain, on rebirth', 7–9; 10; 12
The frame
Father, son, and the mind of sovereignty
Hermes teaches; Tat, his son, asks and receives. Asked for the hymn of the powers, Hermes says that Poimandres, 'the mind of sovereignty', handed down to him no more than what is written, knowing that he could understand the rest by himself. The father–son frame is the convention of the Hermetic dialogues; here it carries the weight of a lineage.
“Poimandres, the mind of sovereignty, handed down to me nothing more than what is written.”
ὁ Ποιμάνδρης, ὁ τῆς αὐθεντίας νοῦς, πλέον μοι τῶν ἐγγεγραμμένων οὐ παρέδωκεν
Corpus Hermeticum XIII, 15
The order of the rite
Corpus Hermeticum XIII in the order it happens: not an argument but an initiation, with a silence at its centre and a hymn at its end.
The Greek Greek of W. Scott, Hermetica I (Oxford, 1924); section numbers of Nock–Festugière (Budé, 1945) and Copenhaver (1992).
Step 1: The request
Tat recalls that Hermes, speaking in riddles, had said no one can be saved before rebirth, and had promised to hand the teaching on when Tat was ready to become a stranger to the world. Tat says he is ready.
In the treatise’s words
“No one can be saved before rebirth.”
μηδένα δύνασθαι σωθῆναι πρὸ τῆς παλιγγενεσίας
Corpus Hermeticum XIII, 1
Step 2: Womb, seed and sower
Asked from what womb and what seed one is reborn, Hermes answers: wisdom in silence is the womb, the seed is the true good, the sower is the will of God; the one born is 'a god, child of God'. And this kind, he says, is not taught: God brings it to remembrance when he wills.
In the treatise’s words
“This kind, my child, is not taught.”
τοῦτο τὸ γένος, ὦ τέκνον, οὐ διδάσκεται
Corpus Hermeticum XIII, 2 — The opening answer ('wisdom … in silence') is read differently by Scott and by Nock–Festugière, so its Greek is not quoted here.
Step 3: Hermes' own report
Hermes cannot describe the birth; he can only report it. He has passed out of himself into an immortal body, and is no longer coloured, tangible or measurable: he has been born in mind.
In the treatise’s words
“I am not now what I was.”
καί εἰμι νῦν οὐχ ὁ πρίν
Corpus Hermeticum XIII, 3
Step 4: What is true
Tat, bewildered, asks what is real. Hermes answers with a run of negations: what is not troubled, not bounded, without colour or shape, unchanging, naked, shining, grasped only by itself — the good.
Corpus Hermeticum XIII, 5–6
Step 5: The instruction
The method is three imperatives. Draw it into yourself and it will come; will it and it happens; still the senses of the body, and the birth of divinity will take place. Then: purify yourself of the irrational tormentors of matter.
In the treatise’s words
“Draw it into yourself, and it will come; will it, and it happens. Leave the senses of the body idle, and the birth of divinity will be.”
ἐπίσπασαι εἰς ἑαυτόν, καὶ ἐλεύσεται· θέλησον, καὶ γίνεται. κατάργησον τοῦ σώματος τὰς αἰσθήσεις, καὶ ἔσται ἡ γένεσις τῆς θεότητος.
Corpus Hermeticum XIII, 7
Step 6: The tormentors named
Tat is surprised to have tormentors within him. Not a few, Hermes answers, and terrible: twelve, with many more beneath them, which through the senses force the human being chained in the prison of the body to suffer.
In the treatise’s words
“… from the irrational tormentors of matter.”
ἀπὸ τῶν ἀλόγων τῆς ὕλης τιμωριῶν
Corpus Hermeticum XIII, 7
Step 7: Silence
Hermes commands silence — the holy silence of a rite, not a pause in a lesson.
In the treatise’s words
“Be silent now, my child, and keep a holy silence.”
λοιπὸν σιώπησον, ὦ τέκνον, καὶ εὐφήμησον
Corpus Hermeticum XIII, 8
Step 8: The powers come
Hermes calls the powers one by one, and the tormentors leave as each arrives — the figure below. The verbs are those of an exorcism: driven out, thrust away, fled.
In the treatise’s words
“Rejoice now, my child, being purified by the powers of God.”

The tent from the zodiac (XIII.12): twelve from the circle, yielding to the decad. A passage Scott brackets as a later addition. Step 9: The new being
Tat, made new, sees not with the eyes but with the activity of mind, and speaks as one no longer confined anywhere.
In the treatise’s words
“I am in heaven, in earth, in water, in air; I am in animals, in plants; in the womb, before the womb, after the womb; everywhere.”
ἐν οὐρανῷ εἰμι, ἐν γῇ, ἐν ὕδατι, ἐν ἀέρι· ἐν ζῴοις εἰμί, ἐν φυτοῖς· ἐν γαστρί, πρὸ γαστρός, μετὰ γαστέρα· πανταχοῦ
Corpus Hermeticum XIII, 11 — Scott adds a verb after the last word; it is omitted here.
Step 10: What rebirth is
Hermes gives the definition only after the event: rebirth is no longer to picture oneself in the body that has three dimensions.
In the treatise’s words
“This is rebirth, my child: no longer to picture oneself in the body extended in three dimensions.”
αὕτη ἐστὶν ἡ παλιγγενεσία, ὦ τέκνον, τὸ μηκέτι φαντάζεσθαι εἰς τὸ σῶμα τὸ τριχῆ διαστατόν
Corpus Hermeticum XIII, 13 — Words as transmitted; Scott moves the sentence earlier and brackets εἰς.
Step 11: The hymn of the powers
Tat asks for the hymn of praise that Hermes had said he would hear from the powers on reaching the Ogdoad, as Poimandres foretold. Hermes gives the secret hymn: all nature is called to listen, and then the powers within him are named again, in the same order as they came — knowledge, joy, self-control, justice, sharing, truth, the good, life and light — each to sing through him. Tat ends by offering a hymn of his own.
In the treatise’s words
“Powers within me, sing to the One and the All.”
αἱ δυνάμεις αἱ ἐν ἐμοί, ὑμνεῖτε τὸ ἓν καὶ τὸ πᾶν
Corpus Hermeticum XIII, 18 — In the hymn's roll of the powers steadfastness falls in a lacuna in Scott's text.
The decad · XIII.10–12
Why ten can expel twelve
When the decad arrives, a birth in mind is put together; it drives out the twelve, and by this birth we are made gods.
Corpus Hermeticum XIII, 10 — As printed by Nock–Festugière and translated by Copenhaver. Scott deletes the clauses naming the decad and the twelve; the Greek is therefore not quoted.
Tat asks how twelve tormentors of darkness can be driven out by ten powers. Hermes answers that the bodily 'tent' was put together from the zodiacal circle, twelve in number; the twelve come in pairs, united in action and not to be told apart — recklessness cannot be parted from anger — and so they yield to ten powers, that is, to the decad.
Corpus Hermeticum XIII, 11–12 — Scott brackets XIII.11c–12 as a later addition; Nock–Festugière and Copenhaver print it. 'Anger' is Nock–Festugière's reading; Scott prints ὁρμῆς, 'impulse'. The treatise ties the twelve to the zodiac as a whole and never assigns a tormentor to a sign.
ἡ γὰρ δεκάς, ὦ τέκνον, ἐστὶ ψυχογόνος
“For the decad, my child, gives birth to soul. Life and light are united, and the unit contains the decad, as the decad the unit.”

A caution
Nag Hammadi Codex VI,6
Beyond the eighth
A second Hermetic initiation survives only in Coptic, in Nag Hammadi Codex VI: the Discourse on the Eighth and the Ninth. A father again leads his son, now past the eighth sphere toward the ninth, through prayer and a vision that cannot be put into words, to a hymn sung in silence. Read together, the two treatises suggest that Hermetic teaching ended in rites, not in doctrines.
The Discourse on the Eighth and the Ninth (Nag Hammadi Codex VI,6), 52.1–63.32 — After the translation of J. Brashler, P. A. Dirkse and D. M. Parrott, in D. M. Parrott (ed.), Nag Hammadi Codices V,2–5 and VI (Leiden, 1979). The last sentence is this page's reading.

- Hermetic Texts as Initiatory Manuals54:05The Seven Sages, Socrates, Plato, and the Hermetic CurrentThe Discourse on the Eighth and the Ninth read as a manual of initiation, with an entry, an invocation, a lecture and a climactic moment in which the higher enters the lower — the shape CH XIII also has — and the Hermetic documents as 'not really discursive … priestly in nature' (55:09). The comparison with Masonic and Golden Dawn ritual is the speaker's.
- Initiation, Teacher-Student Dynamic & Divine Union1:13:30The Seven Sages, Socrates, Plato, and the Hermetic CurrentThe father who leads his son in prayer and chant, has the vision himself, and finds that it transcends words: the Eighth and Ninth again, and the teacher–pupil frame CH XIII shares. (In the chapter just before, 'Poimandres & the Shepherd of Men', Tat is suggested as Poimandres' interlocutor; in CH XIII.15 Hermes says that Poimandres handed down to him no more than what is written.)
- Mystical Nature of Hermetic Writings52:16The Seven Sages, Socrates, Plato, and the Hermetic CurrentFather and son in the Hermetic dialogues read as teacher and apprentice, god and priest, all at once, with the mind of God as the Poimandres' subject; these writings are 'not Socrates in the agora arguing' but 'very very mystical' (53:35).
- Archons as Prison Guards, Teachers, and Planetary Forces35:11Wind, Forms, The Aether, Anamnesis, and th Heptagram WithinNames Corpus Hermeticum XIII (37:40) and then turns to Porphyry's On What Is Up to Us and to 'a vice and a virtue from each planet'. CH XIII gives a different scheme: twelve tormentors tied to the zodiac as a whole, ten powers of God, and no planets.

The Making of Gods
The Asclepius' most dangerous sentence: as the Father makes the heavenly gods, so man makes the gods of the temples — statues ensouled, conscious, foreknowing. Augustine quoted it at length and gave four chapters of the City of God to refusing it (VIII.23–26), which is one measure of how seriously it was taken.

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.

Between the schoolmen and Ficino the Latin Hermes is never lost: Nicholas of Cusa quotes Hermes Trismegistus on the names of God in On Learned Ignorance (1440), and about 1460 a monk, Leonardo of Pistoia, brings a Greek manuscript of the treatises from Macedonia to Florence for Cosimo de' Medici.
1463 – 1614
The Renaissance revival
Cosimo de' Medici has Ficino translate the Corpus before Plato; printed in 1471, the Pimander runs through edition after edition, and Hermes is read as the most ancient theologian.
Fixed points
1614
Casaubon's redating
Isaac Casaubon shows on philological grounds that the Greek of the Corpus is post-Christian. Hermes' claim to primeval antiquity collapses in learned Europe — without ending Hermetic practice in alchemical and Rosicrucian circles.
Note
17th–19th century
1614 – 1888
Underground continuities
The word 'Hermetic' migrates toward alchemy and secrecy; Rosicrucian manifestos, Hermetic compendia, and Masonic legend keep the figure at work beneath official learning.
Fixed points
1888 – 1908
The occult revival claims the name
The Hermetic Order of the Golden Dawn fuses Hermetica, Kabbalah, and ceremonial magic into one curriculum; The Kybalion popularizes seven 'Hermetic' principles that are modern New Thought rather than the ancient corpus.
20th century–present
1924 – present
Scholarly recovery
Critical editions and the Nag Hammadi finds re-situate the Hermetica in Roman Egypt, read as Greco-Egyptian teaching rather than either primeval revelation or mere forgery.
Fixed points

Lodovico Lazzarelli
1447–1500
Poet and Hermetist who translated the remaining treatises and wrote the Crater Hermetis, the revival's most devotional text.
Isaac Casaubon
1559–1614
Philologist whose dating of the Corpus ended its claim to primeval antiquity and redrew the tradition's history.
G. R. S. Mead
1863–1933
Theosophical scholar whose Thrice-Greatest Hermes carried the corpus into the occult revival's hands.

Zosimus of Panopolis
fl. c. 300

Abu Ma'shar
787–886
Baghdad astrologer whose account of three Hermeses — antediluvian, Babylonian and Egyptian — shaped the Arabic and Latin Middle Ages' picture of Hermes.
Francesco Patrizi
1529–1597
Philosopher whose Nova de universis philosophia (1591) printed the Hermetica and proposed them, with the Chaldean Oracles, to replace Aristotle in the schools.
