What are the Hermetica?
Hermetica is the collective name for everything written in the name of Hermes Trismegistus. It is a library and not a single book. One part consists of dialogues in which Hermes instructs a pupil about God, the cosmos and the soul; these include the Corpus Hermeticum, the Latin Asclepius, extracts preserved by the anthologist Stobaeus and texts that survive in Coptic and Armenian. The other part is practical: treatises on the stars, on plants and stones, on alchemy and on charms.
No ancient author assembled the whole, and no fixed list of its contents exists. What unites it is the name of Hermes used as a mark of authority, and a shared conviction that the visible world is bound together by hidden sympathies that a taught person can learn to read.

What sets Hermetica apart
Hermetica is a plural, and that is the point of the word. It gathers texts of very different kinds, written over several centuries by unknown hands, that have nothing in common but the teacher they name. A hymn to the one God and a list of plants ruled by the planets both qualify. The term therefore describes a shelf and makes no claim about a single doctrine, which is why scholars prefer it when they want to avoid implying a unified Hermetic system.
- Philosophical part: Corpus Hermeticum, Asclepius, Stobaeus extracts, Coptic and Armenian texts
- Technical part: works on astrology, alchemy, medicine and magic under the name of Hermes
- Main period: first to third century CE for the philosophical dialogues
- Classic study: A. J. Festugiere, La Revelation d'Hermes Trismegiste, 1944 to 1954
- English translation: Brian Copenhaver, Hermetica, 1992
Often mistaken for something else: Hermeticism is a teaching or movement; the Hermetica are the actual texts, including many that later Hermeticists never read.
The story behind Hermetica
The Greek texts were composed in Egypt under Roman rule, mainly between the first and third centuries CE, though some technical material is older. A. J. Festugiere drew the lasting distinction between learned and popular Hermetica in a four-volume study published from 1944 to 1954. Garth Fowden argued in The Egyptian Hermes (1986) that both kinds came from one milieu. Brian Copenhaver's English translation of 1992 took the word as its title.
Why Hermetica matters
The word stops a reader from mistaking one collection for the whole tradition, and shows how wide the name of Hermes was spread.
How to read Hermetica
Scholars and careful readers say Hermetica when they mean the texts themselves, and keep Hermeticism for the teaching or movement drawn from them.
Hermetica in practice: an example
A student who has read only the Corpus Hermeticum may be surprised to learn that an astrological herbal under the same name also counts as Hermetica.
Where readings of Hermetica go wrong
The attribution to Hermes is a literary convention; the real authors are unknown and wrote centuries later than the legend claims.
Sources and editorial method
This entry summarizes the tradition in the Almanac's own words; where no source is listed, it is an editorial summary rather than a primary text, and symbolic readings are named as the tradition's, not as fact.
The seven principles come from The Kybalion (1908), a modern book; the ancient Hermetic writings do not list them.

Common questions
What are the Hermetica?
They are the surviving writings attributed to Hermes Trismegistus: philosophical dialogues such as the Corpus Hermeticum and the Asclepius, together with practical works on astrology, alchemy and magic.
Is the Hermetica the same as the Corpus Hermeticum?
No. The Corpus Hermeticum is one collection of seventeen Greek treatises within the Hermetica. The wider term also covers the Asclepius, the Stobaeus extracts, Coptic and Armenian texts and the technical works.
How old are the Hermetica?
The philosophical texts date mostly from the first to the third century CE. Renaissance readers believed them far older, a view overturned by Isaac Casaubon in 1614.
