Meaning

A proba is a displayed proof or trial; the tinging-man is the person who undertakes to exhibit it. Khunrath distinguishes the apparent result, its genuine production, possession of the agent, and knowledge of how to prepare that agent. These are four different evidential questions, even when a spectator sees only one performance.

Use in the book

Pages 155–1562 attack the inference that anyone who transmuted must recognize Magnesia and possess the Art. Some performers, Khunrath alleges, obtained tinctures by unphilosophical means; their art lasted only as long as the supply. The same passage separately mentions dishonest projections that spectators mistook for upright demonstrations. The first case does not require the second: within Khunrath's account, a person may produce a genuine effect with an agent he cannot make, or may merely deceive the audience.

The proposed test therefore extends beyond the spectacle. Such people, he says, never prepared the Stone again despite opportunity, whereas Bernard did so four times in old age. This is a claim made in the text, not an independently verified record of those unnamed careers. Page 157 also asks that one judge the bird by its song: hear whether the performer's explanation agrees with Nature. A true Philosopher should not shrink from that examination. The demand complements rather than replaces attention to observed performance.

Pages 158–1602 3 address a more specific claim, that raw matter already transmutates lastingly and thereby proves itself the true subject. Khunrath rejects it because the required regeneration, more-than-perfecting, and other qualification have not occurred. If raw matter sufficed, the elaborate preparation described by the Philosophers would be pointless. The conclusion is practical caution: on page 161 spectators are told to watch the demonstrator's quick hand movements, instruments, and other equipment, and are referred to the warning appended to the German Confessio. The treatise offers vigilance and distinctions, not a catalogue of techniques for imitating fraud.

Places to read

1599 p. 155Successful transmutation is denied automatic authority concerning recognition and preparation.
1599 p. 156Unphilosophical acquisition of tinctures is distinguished from fraudulent projections, and repeat preparation becomes a criterion.
1599 p. 157The performer's speech must be judged at Nature's touchstone rather than the display trusted alone.
1599 p. 158The particular claim that still raw matter can already transmute is introduced as a false boast.
1599 p. 160The necessary sequence of preparation answers that boast.
1599 p. 161The spectator is warned to watch hand movements, instruments, and equipment and directed to the Confessio warning.

Translation in this edition

The translation's 'got by practice' for erpracticiret on page 156 can mislead if heard as diligent laboratory practice; the context makes the acquisition discreditable. Likewise tinge is not always a claim of true transmutation: page 126 explicitly uses it for ordinary colouring of wood or skin. The local qualification transmutatoriè matters.

Source note

The primary comparison with Bernard's four preparations occurs on page 156, not page 155. A claim about the inability of unnamed tingents to repeat preparation remains Khunrath's allegation, even though repeatability is a clear criterion in his reasoning.
