Meaning
The philosophical Athanor is the named furnace of the two constructive preparations. Khunrath also refers to his own Athanor “with the unburnable wick.” The treatise identifies its role and points to another work, but supplies no design, construction dimensions, fuel regime or working temperature. The name’s presence demonstrates technical content without making the book an equipment manual.
Use in the book
The first occurrence central to the argument is on page 95. Silver or gold has been reduced through the first matter and sown into its field; seed and field are then described as coagulated, fixed and incerated together in a philosophical Athanor. The parenthesis recommending Khunrath’s own apparatus is modestly phrased: it would not be unsuitable. It is not an assertion that only his furnace can perform the work.
Page 98 names the Athanor again in the metal-free universal preparation. Here putrefaction, coagulation, fixation and inceration bring the catholic matter to its more-than-perfect condition. The same apparatus-name therefore serves both roads, whose distinction depends upon their materials and timing of specification rather than upon two different furnace types.
The margin at that page refers the reader to Khunrath’s treatise on the philosophical Athanor. This is an authorial cross-reference, not an instruction contained in the present book. Its existence here cannot establish the contents, completion or publication history of the referenced work without further evidence.
The Athanor should also not be mistaken for the only laboratory object mentioned in the treatise. Earlier pages discuss glasses, while the warning against deceptive performances speaks of instruments and work-tackle. Khunrath can be explicit about the site and means of work while withholding the quantitative and material particulars needed to reproduce it. The unburnable wick remains a claimed identifying feature of his apparatus, not a safe technical specification that can be reverse-engineered from this phrase.
Places to read
- 1599 p. 95The special preparation occurs in a philosophical Athanor; Khunrath names his own unburnable-wick version.
- 1599 p. 98The universal preparation also takes place in the philosophical Athanor.
- 1599 p. 98 · marginA separate treatise on the philosophical Athanor is cited.
Translation in this edition
The unburnable-wick phrase occurs on page 95. The supplied Introduction associates it with page 98, where the separate tract is mentioned; the primary page locations should be kept distinct. “Athanor” is retained because expanding it into a particular reconstructed furnace would exceed the text.
Source note
The possessive “my” belongs to the parenthetical apparatus on page 95. It should not be generalized so that every occurrence of “philosophical Athanor” is made an explicit reference to Khunrath’s own design.
