The Corpus Hermeticum,
treatise by treatise
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 §
The vision treatise: a divine mind reveals the origin of cosmos and man, and the ascent of the soul back through the planetary spheres.
The most read and the least typical. Most of what people mean by ‘hermeticism’ comes from this one text.
II
To Asclepius §
On the incorporeal: motion, space and the question of what it means for God to be everywhere.
Technical and Greek-philosophical. Nothing Egyptian about it.
III
The Sacred Discourse §
A compressed cosmogony — creation, the ordering of the elements, the task given to humankind.
The shortest treatise, and textually the most damaged.
IV
The Mixing Bowl, or the Monad §
God sends down a bowl of nous; those who choose to be baptised in it gain mind, those who do not remain merely alive.
The clearest statement in the corpus that understanding is elective, not universal.
V
That God is Both Invisible and Utterly Manifest §
An argument from the order of the visible world to an unseen maker.
Closer to natural theology than to mysticism.
VI
That the Good is in God Alone §
The good belongs to God; what humans call good is at best absence of evil.
Flatly pessimistic about the world — and hard to square with treatise V.
VII
The Greatest Evil Among Men is Ignorance of God §
A short, angry sermon: the body is a tomb, ignorance a drunkenness.
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 §
Nothing is destroyed; what we call death is dissolution and change.
Directly contradicts the world-rejection of VII. The corpus does not resolve it.
IX
On Thought and Sense §
How mind and perception work together, and why the pious understand what others cannot.
Contains the corpus’s working epistemology, such as it is.
X
The Key §
A summary treatise gathering earlier themes: knowledge, ascent, the fate of souls.
Presented as a key to the others, which is itself evidence the collection was already being read as a set.
XI
Mind to Hermes §
Mind instructs Hermes on eternity, cosmos, time and becoming — and tells him to make himself equal to God in order to understand God.
Home of the most audacious instruction in the corpus.
XII
On the Mind Shared §
Mind is common to all; providence, necessity and fate are examined and ranked.
The treatise that most resembles Stoic school teaching.
XIII
On Rebirth §
The initiation text: Hermes leads Tat through palingenesia, the driving out of twelve torments by ten powers.
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 §
A letter arguing from the fact of making to the existence of a maker.
Brief, and closer to an argument than a revelation.
XVI
Definitions of Asclepius to King Ammon §
On the sun as demiurge, the ordering of daimons, and a warning that translating the text into Greek will destroy its force.
The warning is pointed: the text we read in Greek says Greek will ruin it.
XVII
(fragment) §
A few lines on images and why likenesses of the incorporeal are not absurd.
Too short to interpret safely. Often skipped.
XVIII
On the Soul Hindered by the Body §
An encomium of kings, in rhetorical form.
Widely judged not to belong with the rest: no Hermes, no revelation, different register.
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.
