IV. THE CLASSICAL & IMPERIAL WORLD — c.200 BCE – 500 CE
How many
No organised body; a foundational current in Western esotericism, alchemy, Rosicrucianism and modern occultism.
Who began it
Attributed to Hermes Trismegistus, thrice-great Hermes, a fusion of Greek Hermes and Egyptian Thoth, presented as an ancient Egyptian sage. He is not historical; the texts are Greek compositions of the Roman period written by unknown authors.
What it is for
To know God, the cosmos and the self as a single connected order, and thereby to be reborn during this life.
What it worships
A supreme God, called Nous or the One, from whom the cosmos proceeds. Also the planetary powers and the Egyptian gods in philosophical dress.
What it holds
As above, so below — the famous formula from the Emerald Tablet, asserting correspondence between macrocosm and microcosm. Humanity is uniquely dual, divine in mind and mortal in body, and can ascend by knowledge. The cosmos is good and alive, not a prison — which is the sharp dividing line between Hermeticism and Gnosticism, despite their surface similarity. The Asclepius contains a famous lament for Egypt, mourning a coming age when the gods will leave and the land will be full of tombs.
What it does
Contemplation and instructed dialogue between master and pupil. A rebirth experience described in the thirteenth treatise. Astrology, alchemy and the animation of statues (in the Asclepius) — the practical side that the Renaissance seized on. There was no church, no clergy and no congregation; transmission was teacher to student.
After death
Ascent through the seven planetary spheres, surrendering at each the vice that sphere imparted — greed to one, deceit to another — until the soul enters the eighth sphere purified and finally becomes part of God. The Poimandres treatise describes this in detail. It is the same structure as Gnostic ascent, without the hostility to the world.
Its texts
The Corpus Hermeticum, seventeen Greek treatises, chief among them Poimandres. The Asclepius, surviving in Latin. The Emerald Tablet, an Arabic-transmitted alchemical text. Nag Hammadi also yielded Hermetic material, confirming its Egyptian setting.
Its branches
Philosophical Hermetica; technical Hermetica (astrology, alchemy, magic); Renaissance Hermeticism; modern Hermetic orders.
Of note
Casaubon's redating in 1614 is one of the earliest triumphs of historical-critical textual scholarship, and it killed a tradition's credibility with a philological argument rather than a theological one.
Its timeline
- c.100–300 CE The Greek Hermetica composed in Roman Egypt.
- c.700–1000 CE Transmission and elaboration in Arabic; the Emerald Tablet appears.
- <strong>1460 CE</strong> A monk brings a Greek manuscript of the Corpus Hermeticum to Florence. Cosimo de' Medici orders Ficino to stop translating Plato and translate this first, believing it older and more authoritative.
- 1471 CE Ficino's Latin translation printed; Hermeticism becomes central to Renaissance thought.
- 1614 CE Isaac Casaubon demonstrates on linguistic grounds that the texts are Roman-era Greek, not ancient Egyptian. The intellectual prestige collapses almost overnight.
- 1600 CE Giordano Bruno burned in Rome; his Hermetic commitments were part of the case.
- 1614–17 Rosicrucian manifestos; the esoteric line continues underground.
- 1888 Hermetic Order of the Golden Dawn founded, reviving the label.
