The Corpus Hermeticum,
treatise by treatise

TL;DR

Seventeen short Greek treatises, not one book. They contradict each other in places, and that is the most useful thing about them. One entry each — plus the reason the numbering skips fifteen.

People say the Corpus Hermeticum as though it were a book with an argument. It is a collection: seventeen short Greek treatises, assembled by someone we cannot name, in an order nobody can justify, written across perhaps two centuries. They do not agree with each other. Treatise VII calls the body a tomb; treatise VIII says nothing that exists ever perishes. Both are in the corpus. Neither wins.

That disagreement is the single most useful fact about the collection, and the one most often smoothed away. What follows is the whole corpus, one entry each: the traditional title, what the treatise argues, and what is worth knowing about it.

I
Poimandres §
What it argues. The vision treatise: a divine mind reveals the origin of cosmos and man, and the ascent of the soul back through the planetary spheres.
What it does not settle. It reports a vision; it does not give a method. Nothing in it says how the ascent could be repeated by anyone else, or whether the revealing Mind is God or a distinct being.
The most read and the least typical. Most of what people mean by ‘hermeticism’ comes from this one text.
II
To Asclepius §
What it argues. On the incorporeal: motion, space and the question of what it means for God to be everywhere.
What it does not settle. It does not say which philosophical school it accepts. The argument uses Greek technical vocabulary without committing to a system, which is why later readers could claim it for several at once.
Technical and Greek-philosophical. Nothing Egyptian about it.
III
The Sacred Discourse §
What it argues. A compressed cosmogony — creation, the ordering of the elements, the task given to humankind.
What it does not settle. The text is damaged. Several sentences cannot be reconstructed with confidence, and translations differ on what they say — so any reading of the detail is partly editorial.
The shortest treatise, and textually the most damaged.
IV
The Mixing Bowl, or the Monad §
What it argues. God sends down a bowl of nous; those who choose to be baptised in it gain mind, those who do not remain merely alive.
What it does not settle. It does not say why some accept the bowl and others do not. The choice is asserted; its ground is not given.
The clearest statement in the corpus that understanding is elective, not universal.
V
That God is Both Invisible and Utterly Manifest §
What it argues. An argument from the order of the visible world to an unseen maker.
What it does not settle. It argues from the order of the world to a maker, but never shows why order requires a maker rather than being a property of things.
Closer to natural theology than to mysticism.
VI
That the Good is in God Alone §
What it argues. The good belongs to God; what humans call good is at best absence of evil.
What it does not settle. It does not explain how a world that is not good comes from a God who alone is. The conclusion is stated; the origin of the gap is not.
Flatly pessimistic about the world — and hard to square with treatise V.
VII
The Greatest Evil Among Men is Ignorance of God §
What it argues. A short, angry sermon: the body is a tomb, ignorance a drunkenness.
What it does not settle. It names the illness and prescribes nothing. No practice follows from it — which is worth noticing, given how often the corpus is sold as a practice.
The most Gnostic-sounding text in the corpus, and the usual exhibit for those who read hermetism as world-denying.
VIII
That Nothing That Is Perishes §
What it argues. Nothing is destroyed; what we call death is dissolution and change.
What it does not settle. ‘Nothing perishes’ is said of the whole. Whether the individual survives in any recognisable form is left open.
Directly contradicts the world-rejection of VII. The corpus does not resolve it.
IX
On Thought and Sense §
What it argues. How mind and perception work together, and why the pious understand what others cannot.
What it does not settle. It offers no test. Nothing inside the treatise distinguishes understanding from the confident feeling of having understood.
Contains the corpus’s working epistemology, such as it is.
X
The Key §
What it argues. A summary treatise gathering earlier themes: knowledge, ascent, the fate of souls.
What it does not settle. As a summary it restates rather than decides. Where the earlier treatises disagreed, it does not adjudicate between them.
Presented as a key to the others, which is itself evidence the collection was already being read as a set.
XI
Mind to Hermes §
What it argues. Mind instructs Hermes on eternity, cosmos, time and becoming — and tells him to make himself equal to God in order to understand God.
What it does not settle. It does not say how the instruction could be carried out, or what would count as having done it.
Home of the most audacious instruction in the corpus.
XII
On the Mind Shared §
What it argues. Mind is common to all; providence, necessity and fate are examined and ranked.
What it does not settle. The ranking of providence, necessity and fate is asserted rather than argued. Nor does it explain how a mind shared by everyone leaves room for anyone to be wrong.
The treatise that most resembles Stoic school teaching.
XIII
On Rebirth §
What it argues. The initiation text: Hermes leads Tat through palingenesia, the driving out of twelve torments by ten powers.
What it does not settle. It does not identify the twelve and the ten in any way that could be checked against something else. Whether such a rite was ever performed, or is a literary form, is not settled by the text.
The only treatise that reads like a rite rather than a lecture, and the one that most supports reading the corpus as a practice.
XIV
To Asclepius, Health of Mind §
What it argues. A letter arguing from the fact of making to the existence of a maker.
What it does not settle. The argument from making to a maker establishes nothing about the maker beyond the bare fact of having made.
Brief, and closer to an argument than a revelation.
XVI
Definitions of Asclepius to King Ammon §
What it argues. On the sun as demiurge, the ordering of daimons, and a warning that translating the text into Greek will destroy its force.
What it does not settle. It does not survive in the language it claims is proper to it, so its central warning cannot be tested from inside the text we have.
The warning is pointed: the text we read in Greek says Greek will ruin it.
XVII
(fragment) §
What it argues. A few lines on images and why likenesses of the incorporeal are not absurd.
What it does not settle. It is too short to carry a conclusion. Almost any reading of it is supplied by the reader rather than found in the fragment.
Too short to interpret safely. Often skipped.
XVIII
On the Soul Hindered by the Body §
What it argues. An encomium of kings, in rhetorical form.
What it does not settle. It does not mention Hermes and makes no claim to revelation. What it is doing inside this collection is unresolved.
Widely judged not to belong with the rest: no Hermes, no revelation, different register.

Where they disagree

The collection is usually read as if it had one doctrine. It does not, and the disagreements are not subtle. Four are worth holding in mind, because almost every popular summary of ‘hermetic teaching’ quietly picks one side and drops the other.

Is the world evidence of God, or is it the problem? V argues from the order of the visible world towards its maker. VI holds that the good is in God alone and that what people call good here is at best the absence of evil. Both positions are in the same collection.
Is the body a tomb, or is nothing ever lost? VII preaches that the body is a tomb and ignorance a drunkenness. VIII holds that nothing that is ever perishes. Neither treatise acknowledges the other.
Is mind given to all, or to those who choose it? XII says mind is common to all. IV has God send down a bowl of mind, in which some are baptised and others are not.
Is understanding taught, or undergone? IX and XIV argue. XIII stages something closer to a rite. The corpus never says which of these it is.

Scholarship has long described these as an optimist and a pessimist strand — the distinction is associated above all with Festugière’s study of the 1940s and 50s. Later work has questioned how cleanly the collection divides that way, and the safer statement is the plain one: this is an anthology, not a system, and it was never edited into agreement.

Why there is no treatise XV

The numbering runs I–XIV, then jumps to XVI. Nothing is lost. Early modern editions filled the fifteenth slot with an entry from the Suda, a tenth-century Byzantine encyclopedia, plus three excerpts preserved by Stobaeus. Later editors recognised that this material did not belong and removed it — but kept the numbering, so that references in the older scholarship would still work. The gap is a scar from a correction, not a missing text.

What the corpus is not

It is not the whole of ancient hermetic literature. The Asclepius survives separately in Latin, the Stobaean fragments preserve treatises that did not make the collection, and the Nag Hammadi codices produced Coptic hermetica nobody had seen for centuries. The corpus is the part that survived by being copied, which is not the same as the part that mattered most.

Fair questions

Why seventeen and not eighteen?

The numbering runs I–XIV and XVI–XVIII. Treatise XV was removed as spurious, and editors kept the gap so older references would still resolve.

Which treatise should I read first?

I, Poimandres — but knowing that it is the least typical of the collection. Read XIII next if you want the practice, VIII if you want the argument.

Are these translations?

No. These are summaries of what each treatise argues. For the texts themselves in English, Copenhaver (1992) is the standard; the Greek is in Nock and Festugière.
