Western Esotericism
Hermeticism
This guide helps you get your bearings in Hermeticism before you start exploring the interactive timeline, framework graph, and concept maps.
Before You Dive In
- Hermeticism is based on the Corpus Hermeticum, a set of Greek-Egyptian texts (2nd–3rd century CE) attributed to Hermes Trismegistus — a legendary fusion of the Greek Hermes and Egyptian Thoth.
- The tradition had two major lives: the original late-antique writings, and a massive Renaissance revival after Marsilio Ficino translated the Corpus Hermeticum in 1463, believing it was older than Moses.
- Start with the core idea: the human being is a microcosm reflecting the macrocosm ("as above, so below") — this principle connects Hermetic philosophy to alchemy, astrology, and natural magic.
- Academic study of Hermeticism was transformed by Frances Yates's "Giordano Bruno and the Hermetic Tradition" (1964), which argued that Hermeticism was central to the Scientific Revolution — a claim still debated.
- Modern scholarship (Wouter Hanegraaff, Antoine Faivre) treats Hermeticism as part of "Western esotericism," a legitimate field of intellectual history, not a fringe curiosity.
Key Terms to Know

"As above, so below"The principle of correspondence between macrocosm (universe) and microcosm (human being) — from the Emerald Tablet.

Common Confusions
Thinking Hermeticism is ancient Egyptian religion — the texts are Greco-Egyptian, written in Greek during the Roman period, blending multiple traditions.
Confusing Hermeticism with hermeticism (lowercase) meaning "sealed" or "airtight" — the word derives from the same root but the philosophical tradition is specific.
Assuming Hermeticism is purely mystical — the texts contain sophisticated philosophical arguments about mind, matter, and the nature of God that engage with Platonism and Stoicism.

2012How to Use the Interactive View
1
Explore the timeline
Open the interactive view and scan the framework timeline. Which frameworks came first? Which ones overlap? Where are the big transitions?
2
Read the articles
Click into individual frameworks to read what each one claims, where it came from, and how it relates to its neighbors.
3
Check the concept map
See how the key ideas within a framework connect. This is useful for figuring out what to learn first and what depends on what.
4
Test yourself
Take the quiz for any framework you've read about. It's a quick way to find out whether you actually understood the core ideas or just skimmed them.
