At a Glance
- The wordMetempsychosis ordinarily concerns transmigration of souls; Vaughan deliberately assigns it to the last transmutation performed with the elixir or qualified medicine.
- In this bookHe says that the word has caused errors concerning the soul, then claims that Pythagoras applied it only to magic’s secret performances. This exclusivity is Vaughan’s assertion, not an established biographical fact supplied by the edition (p. 95 · Passage A).
- In this editionThe technical name is retained. “Qualified Medicine” becomes “tempered medicine,” connecting this paragraph to the preceding bodily fermentation.
- A place to read1651, p. 95, read immediately after the account of descent on pp. 94–95 (pp. 94–95 · Passage A; p. 95 · Passage A).
Meaning
The entry’s chief distinction is between a received soul-related sense and Vaughan’s claimed operative sense. He does not merely add a metaphorical comparison to a discussion of reincarnation. He states that metempsychosis signifies the final transmutation in the secret art and gives the qualified medicine as its agent. The paragraph thus appropriates the word to the sequence he has just explained (p. 95 · Passage A).
“Last” is consequential. Spiritual fermentation multiplies tinctures; bodily descent tempers the completed medicine; metempsychosis names the concluding application of the tempered product. Treating the three as interchangeable names for any transformation would remove the ordering that his late polemic seeks to establish (pp. 93–94 · Passage A–p. 95 · Passage A).
Use in the book
The preceding account explains why the agent has two names here. In its less bodily condition, the medicine is described as a subtle, moist fire. Incorporation brings it to a portable dust, which Vaughan calls the Arabian elixir. “Elixir” and “qualified medicine” therefore point to the moderated condition suited to the last transmutation, rather than supplying two unrelated ingredients (pp. 94–95 · Passage A; p. 95 · Passage A).
Vaughan’s remark about Pythagoras carries a strong polemical ambition. The word has occasioned errors about the soul, he says, but Pythagoras applied it only to magical performances. The “only” should remain visible as part of his assertion. It cannot be detached from its speaker and offered as a reliable account of every Pythagorean teaching. The supplied note explicitly distinguishes the ordinary soul-related sense from Vaughan’s exclusive interpretation (p. 95 · Passage A).
The historical paragraph goes on to claim a conversion of quicksilver into gold that will pass the royal test without diminution. The lexicon need not reproduce the source’s ratio or directions to explain the claim. What matters for the vocabulary is that this is the final action of the prepared elixir, and that the test is invoked as the proposed result’s endurance under assay. The supplied edition does not independently demonstrate the transformation or specify the test’s method (p. 95 · Passage A).
This deliberately narrow usage contrasts with the broader transmutation of the regeneration section. There Vaughan connects change to salvation and resurrection; here he gives a terminal operation of the magical medicine. The juxtaposition should neither turn the final claim into a purely spiritual allegory nor make the salvation paragraph an ordinary metals recipe. Vaughan wants the natural and religious registers to communicate, while still naming different immediate objects and results (pp. 92–93 · Passage A; p. 95 · Passage A).

In this edition
The edition preserves “metempsychosis” rather than replacing it with “transmigration,” which would conceal Vaughan’s deliberate reassignment. It renders “Qualified Medicine” as “tempered medicine,” keeping the connection with the moderation described in the previous paragraph. “Royal test” is left at the level the source supports: testing or refining gold, with no method specified in this passage (pp. 94–95 · Passage A; p. 95 · Passage A).
Historical forms and local uses: Metempsychosis, Vaughan’s name for the last transmutation; Qualified Medicine, the tempered agent used at the final stage; Test Royall, the asserted test of the resulting gold; last Transmutation, the final use of the qualified medicine.
Qualified medicine
Qualified Medicine. The tempered medicine or elixir used in the last transmutation Vaughan calls metempsychosis. The qualification is the reduction of intensity described in the preceding bodily fermentation. It does not mean a medicine clinically tested or certified for therapeutic use.

Royal test — Test Royall
Test Royall. The test Vaughan says the claimed gold will pass without diminution. It functions as a standard of the asserted transformation’s adequacy, but the passage does not specify an assay procedure. The lexicon preserves the claim’s role without treating the transformation as independently demonstrated.
