Meaning

Projection is the application of the prepared metallic medicine upon lower metals. It is an act directed upon a material, whereas transmutation names the change alleged to follow. Khunrath’s distinction is explicit in the syntax of page 160: projection upon the lower metals, transmutation into the upper. Neither is simply another word for fermentation.

Use in the book

Page 89 connects philosophical projection with more-than-perfected silver or gold. The principle that like begets like requires silvern or golden determination, while the qualification “more-than-perfected” denies that ordinary metal already has the needed efficacy. Page 91 repeats the relation as the production of like fruits out of lower metals with the help of Art.

In the second road, page 100 orders the operations carefully. Fermentation first raises metals into the higher condition; projection then allows them to multiply their kind in a moment. A description of a projected material is therefore incomplete unless one also asks how it was prepared and from what ground it came.

The later polemic complicates the evidential value of a visible projection. Pages 155–1562 distinguish having a tincture from knowing its matter and preparation; a person might display a transmuting work only for as long as his supply lasted. The passage also expressly sets dishonest projections aside as a further problem. It does not claim that every display is fraudulent, but it refuses to make a display alone proof of the operator’s philosophical knowledge.

Pages 158–161234 target a more specific boast: that still-raw matter already produces lasting transmutation. Khunrath counters with the labour required to attain the wonder-working Stone and warns the onlooker to attend to handlings and instruments. The operation-name must consequently be read with its qualifications. “Projection” can identify a genuine application within the doctrine, an improperly interpreted performance, or a deceitful display; the mere report of a casting-on does not decide which.

Places to read

  1. 1599 p. 89Projection depends upon more-than-perfected silver or gold.
  2. 1599 p. 91Like fruits are said to be produced from lower metals in philosophical projection.
  3. 1599 p. 100Projection follows fermentation and effects multiplication of kind.
  4. 1599 p. 156Possession of a tincture and dishonest projections are distinguished from knowledge of preparation.
  5. 1599 p. 160Projection upon lower metals is grammatically distinguished from transmutation into upper metals.
  6. 1599 p. 161The spectator is warned to inspect the performer’s handlings and apparatus.

Translation in this edition

“Projection” is retained rather than rendered as a vague “transmutation.” The explanatory “casting-on” clarifies the act without supplying instructions for quantities, materials or handling. The epistemic limits of performance belong to the reading of the word, not to a modern demonstration that any reported metallic change actually occurred.

Source note

The contrasts upon/into on page 160 are load-bearing: they distinguish the operation’s target from its proposed result. A translation that makes both clauses simply “changing metals” loses this precision.
