Emerald Tablet

Definition

The Emerald Tablet is a short Hermetic text attributed to Hermes Trismegistus: a dozen lines carrying the sentence popularly condensed to as above, so below and a compressed account of the alchemical Great Work. It surfaces first in Arabic, and Latin Europe read it as alchemy's founding charter.

Primary source

Tis true without lying, certain & most true. That which is below is like that which is above & that which is above is like that which is below to do the miracles of one only thing

— Tabula Smaragdina, fol. 2r, the English translation in Newton's Keynes MS. 28 (undated in the manuscript), King's College, Cambridge; normalized transcription, The Chymistry of Isaac Newton, Indiana University. Open-access copy

Deep Understanding

In fewer than a dozen lines the Tablet lays out a whole worldview: the unity of all things, the correspondence between planes of existence, and the methodology of transmutation. The sentence quoted above, in the English translation preserved in Newton's Keynes MS. 28, is the one that became the Hermetic Principle of Correspondence. Note what it actually says. It is not a claim that the two planes are identical. It is a claim that each is like the other, and that the likeness is there to do the work of one only thing.

Newton's manuscript matters for a second reason. The Tablet is usually met as an ancient curiosity, quoted in the voice of antiquity. His copy carries it in English, with the Latin on a later folio and a Latin commentary after it — the man who wrote the Principia kept this text in his working papers. Whatever the Tablet is, it was not a museum piece to the people who built mechanics.

The earliest known version appears in Arabic texts of the eighth century; the tradition itself claims far greater antiquity, and no manuscript supports that claim. It passed into Latin in the twelfth century and became the foundational text of medieval European alchemy.

The Tablet does not stop at correspondence. It describes an operation: the separation of the subtle from the gross, the ascent from earth to heaven and the descent back again, force gathered through repetition. Read as chemistry it is nearly useless, which is part of why it survived — every generation could read its own work into it.

Often confused with

The Kybalion: a 1908 book that systematises the Tablet's correspondence into seven principles, where the Tablet itself names none. Hermetic Principles: that later system of seven, not the Tablet's own content. Hermes Trismegistus: the legendary author the text is attributed to, where this is the text.

In Practice

Hold the condensed form, as above, so below, as a diagnostic rather than a slogan. When something in the outer life is out of true, look for the inner state it is like. Then do the harder half, which the Tablet insists on and most readings drop: the descent. The line has the thing ascend to heaven and come back down to receive the force of what is above and below. An insight that stays up there is half an operation.
