Meaning
A signature is a mark by which something about a natural thing becomes intelligible. The treatise uses signatura sparingly and in two distinct settings: the finished Stone's ruddy diadem and the reading and observation of natural things. Neither occurrence by itself supplies a full catalogue of signatures or a method for identifying the unnamed matter.
Use in the book
Page 55 calls the Stone's most ruddy diadem the signature of highest perfection. The phrase concludes the numerical and operative account in which the one subject contains the Philosophers' one, two, three, and four and yields a real physical ten. The visible mark therefore belongs to the account of completion and perfection. It should not be transferred without qualification to the raw matter or treated as an isolated colour that proves success.
The second occurrence stands in the margin of page 136. Khunrath is explaining how true Philosophers can know the Art before fully completing it: diligent reading and sound understanding of truthful books, theosophical contemplation and meditation, and observation of natural workings in the great world and the laboratory. 'Hither belongs the signature of natural things' attaches signature to this complex of practices. It names something to be considered within educated observation, rather than a shortcut that cancels reading, judgement, or divine illumination.
The restriction becomes clear beside pages 71–7323, where blackness and peacock's-tail colours are explicitly denied sufficient evidential force. Many preparations can exhibit similar colours. A sign must therefore be understood in relation to its subject and to the natural account of what has happened to it. The red diadem can be called a signature in Khunrath's affirmative description without licensing the inference that every red product is the Stone. The two passages illustrate the book's larger rule: resemblance is not recognition until its grounds are supplied.
Places to read
- 1599 p. 55The most ruddy diadem is called the signature of highest perfection at the close of the one-through-ten account.
- 1599 p. 72Colour alone is a fallible sign because many other preparations display similar appearances.
- 1599 p. 136 · marginThe signature of natural things is assigned to the account of reading, contemplation, and observation in the body text.
Translation in this edition
The supplied edition retains Signature, preserving the recognizable Latin term while leaving its particular object to the passage. Its modern note explains a general doctrine of signatures; the primary margin here states only that signature belongs to the process being described. A detailed claim about how every thing displays its virtue would need evidence beyond these two occurrences.
Source note
The supplied Introduction mentions a separate work associated with natural signatures. That bibliographical statement is editorial background; this article's account of the term rests on the two occurrences in the 1599 treatise.
