At a Glance

  • The wordA medium is something intervening or assisting between two subjects. Here its role is to make their otherwise impossible union possible.
  • In the bookIn the third lesser way, damaged sulphur must be strengthened so that fixed salt and volatile spirit can unite. The same assistant becomes harmful if it ascends at a later stage.
  • In this edition“Medium” is retained, together with “sulphurous” and “bituminous.” The printed “Copavian” and “Italian” are not silently converted into named substances.
  • A place to readLesser VI–VII and XVI–XVII (1690, pp. 65–66, 71–72), where the necessary help and its later limit are both explicit.

Meaning

Medium names a function before it supplies an identification. The third lesser way begins with a fixed vegetable salt and its own volatile sulphurous spirit, available, according to the author, from an ordinary chymist. Their mere availability does not mean that they are ready for the philosophical union. The purest sulphur, containing the soul, has suffered harm during unphilosophical preparation. The sulphurous medium is introduced because this damage prevents the two subjects from being joined inseparably (VI).

The author then describes a plant-derived, sulphurous and bituminous matter, obtained from a plant living or dead and known in several parts of the world. “Copavian” is preferred, followed by “Italian” (VII). These descriptions are more specific than a wholly unnamed assistant but less specific than a securely identified modern material. The lexicon should preserve exactly that degree of knowledge.

Use in the book

The explanation links soul, body and spirit in a causal order. By strengthening the soul, the medium makes body and spirit capable of perfect union. VII then describes the same help in terms of the fixed salt: its pores and atoms are dilated, and it is fortified so that it can receive its own spirit. The bodily image of opening and the language of restoring the soul are not separate alternative accounts offered by the text. They are coordinated descriptions of the preparation’s claimed receptivity.

The following aphorisms make this receptivity a vulnerable condition. The medium is involved in imbibition and saturation; repeated motion assists its entry into the body (VIII–IX). The opened salt is liable to inappropriate determination from another subject (X). If saturation does not occur within the author’s stated interval, the reader is told to suspect a mistaken understanding of the salt, a mistaken understanding of the medium, or faulty management of the imbibitions (XI). The distinction among these possible causes matters: failure does not automatically identify a single wrong ingredient.

At XIV the strengthened sulphurous spirit enters the prepared salt’s pores and facilitates volatilisation and union. The medium’s decisive service has therefore been to make an initial condition possible. XVI insists that it must not ascend during the subsequent distillations. Before spiritualisation, its cooperation is indispensable; as the work proceeds, its cooperation in that ascent would subvert the operation. This is not an inconsistency to be removed by deciding that the medium is always good or always bad. The author assigns it a changing role across stages.

XVII makes its unwanted ascent a sign of excessive heat. The problem is not that the medium has ceased to be sulphurous, nor that it was unnecessary from the beginning. The wrong heat carries forward what should no longer accompany the union. The article thus provides an unusually clear local example of a wider reading rule: a material’s value depends on where it belongs in the process. A helper may enable conjunction without belonging to the final conjunction in the same way as the subjects it helped unite.

In this edition

The edition retains “Copavian” and leaves “Italian” equally unspecific; note 94 explains why no modern botanical identification is inserted. “Feculent parts” at VII becomes “foul parts,” describing what the author says must be removed, not naming an analytical constituent. At XVI the modern reading omits the source’s repeated “to” in “to to them both” while preserving the important contrast between earlier and later cooperation. The note on that aphorism expressly guards the medium’s changing role.

Historical forms and local uses:

sulphureous Medium [printed English phrase] — The assisting material needed for union in the third lesser way, but not to ascend with the united product. (Vegetable Elixir · Aphorism VI; Vegetable Elixir · Aphorism XVI)

bituminous Matter [printed English phrase] — The plant-derived material said to strengthen the salt and make reception of its spirit possible. (Vegetable Elixir · Aphorism VIII)

Copavian [English printed form] — The author’s preferred kind or provenance of the medium, retained without settled modern identification. (Vegetable Elixir · Aphorism VII)

Italian [English printed form] — The second preference named for the medium, without a specific modern substance being identified. (Vegetable Elixir · Aphorism VII)
