The claim
As above, so below. The cosmos is a single living whole in which every level corresponds to every other, and the human being is a microcosm containing the pattern of the whole.
What it held
In 1463 Cosimo de' Medici told Ficino to put aside Plato and translate a newly acquired Greek manuscript first. The Corpus Hermeticum was believed to be the work of Hermes Trismegistus, an Egyptian sage contemporary with or older than Moses, and therefore a witness to a primordial revelation that Plato had merely inherited.
That belief is what made the texts matter. If ancient Egyptian wisdom agreed with Christianity, then Christianity was confirmed from outside, and a Christian could study magic, astrology and alchemy as recovery of a lost knowledge rather than as heresy.
The consequences were substantial and mixed. Bruno's infinite universe and Campanella's cosmology come out of this. Newton's alchemical papers, which Keynes bought and read with astonishment, belong to it. So does a great deal of nonsense.
In 1614 Isaac Casaubon showed by philological analysis that the texts are late antique Greek, not ancient Egyptian — they quote the Septuagint and use vocabulary that did not exist earlier. The entire foundation collapsed, and the movement with it, though the influence had already been absorbed.
How it argued
Translation, commentary and correspondence-thinking — reading resemblance between levels as evidence of real connection.
What it was arguing against
Aristotelian scholasticism, and the separation of the human being from a cosmos assumed to be indifferent.
Where it disagreed with itself
How much Hermeticism contributed to the scientific revolution — Yates argued a great deal, and her thesis has been much attacked and never entirely dismissed.
Common misconceptions
That the texts are ancient Egyptian. They are Greek, from the second and third centuries CE, and the misdating is the single most consequential error in the history of European scholarship.
How it began
Ficino's translation for Cosimo de' Medici in 1463, made in preference to Plato because the manuscript was thought to be older.
What became of it
Ended as a serious intellectual position by Casaubon's dating in 1614, and continuing afterwards as an occult tradition rather than a scholarly one.
Lasting influence
Renaissance magic, Bruno, Paracelsian medicine, alchemy including Newton's, Freemasonry, and the whole modern Western esoteric tradition.
Why it still matters
It is the best case study in how a dating error can reorganise a culture's intellectual life, and in what happens when the error is corrected.
Put another way
A forged pedigree that gets the family into the room, where they then do real work.
Where to start
Yates, then the Corpus itself. Without the historical setting the texts read as fog.
The surprising bit
Newton wrote more on alchemy and Hermetic subjects than on physics. Keynes bought the papers at auction in 1936 and said that Newton was not the first of the age of reason but the last of the magicians.
In their own words
That which is above is like that which is below.
Man is a great miracle, a living thing to be worshipped and honoured.

The verdict
A misdated library that shaped two centuries of European thought and was demolished by one philologist.
