- The wordA region is a place or sphere in an ordered account of Nature. Here it is not a geographical location disclosed by coordinates.
- In the bookThe region of light is the universal meeting place where descending Ideas acquire bodies. Its alternative name, the night of the body, makes the threshold between brightness and material obscurity visible.
- In this edition“Region of light” and “night of the body” translate Regio Lucis and Nox Corporis without making either name cancel the other.

Meaning
Vaughan’s region gathers a group of apparently unlike places: meadow, garden, mountain and meeting place. They are introduced as names used by different philosophical authorities, not as stages on a literal itinerary (p. 125 · Passage 1). The term’s most direct explanation is functional. It is where Ideas descending from the bright world to the dark world are incorporated. “Incorporated” here means given bodily existence; it does not mean that previously independent institutions are combined.
Calling the region universal does not mean that it is unimportant where influences are received. Precisely where and how reception takes place becomes Vaughan’s test of competing claims to knowledge (p. 126). Universality concerns its relation to the whole range of generated things. Secrecy concerns the difficulty of recognising it. A universal principle can be everywhere relevant without being obvious to the person who merely possesses its name.
Use in the book
The region’s immediate setting is the account of Pan, Proteus and Mercury. After making universal Nature the source of particular creatures, Vaughan asks about the birth of Mercury and its place (p. 124 · Passage 1; p. 124 · Passage 2). The new section therefore addresses a question generated by the preceding explanation: if the universal subject interprets all particulars, where does that mediating subject belong? The “region” is introduced to answer this, not simply to embellish the work with another mysterious title.
The answer first comes as a short Latin oracle attributed to Zoroaster. Powers associated with Ideas leap up through shining worlds; beneath them lies a primal meadow (p. 124 · Passage 3). Vaughan’s following explanation takes that meadow as the philosophers’ known place. He relates it to the garden and mountain of the seven metals attributed to Flamel, but does not establish these names by independent description. The lexicon should preserve the chain of attribution: an oracle as Vaughan receives it, his explanation, then further names offered as corroboration.
At p. 125 · Passage 1 light and night become paired names for one region. It is called light’s region by one authority and the body’s night by the Kabbalist. The pairing is comprehensible because the place is a threshold of embodiment. Viewed through the powers arriving there, it is connected with light; viewed through the obscurity of bodily reception, it is night. This is an interpretation of Vaughan’s sequence, not an explicit definition of two separate geographical zones. He himself says the terms are apt and moves directly to incorporation.
The passage next distinguishes the condition of spirits in heaven from their condition after descent into the elemental womb (p. 125 · Passage 1; p. 125 · Passage 2). Above the moon they contract no impurities; in matter they acquire the stain Vaughan calls original leprosy. This creates a tension within the region’s promise. Embodiment makes powers accessible within the natural world, yet reception also exposes them to corruption. The region is not simply a heaven insulated from material danger. It is where the relation between celestial source and material condition becomes decisive.
Agrippa’s cited explanation makes the relation more precise. Influence is good in its higher course but becomes base when received in a baser subject (p. 126). Vaughan develops this as corruption. The place of reception cannot therefore be separated from the quality of what receives. Knowing the existence of heavenly powers would not yet explain their altered earthly effects. A theory that overlooks the recipient overlooks the very mediation the region names.
This is why the subsequent satire of astronomers and natural philosophers belongs to the argument, rather than merely interrupting it. Vaughan asks them to establish where influences are received and to prove their presence in the elements by experience (p. 126). He contrasts diagrams and syllogisms with a magical art that claims to put influences in the hands (p. 127 · Passage 1). His standard is strikingly tangible even when the objects are called invisible. The source reports his claim; it does not supply independent verification that such demonstration occurred.
The invitation to enter the region’s treasures then leads immediately to the universal subject and the two mineral seeds (p. 127 · Passage 1). Thus the region is both a cosmological meeting place and a way of organising a promised disclosure. It links the earlier universal source to the later account of elemental composition and living reduction. To read it only as a landscape of mystical escape would miss the return to bodies; to read it as a plainly named chemical location would miss the deliberate reserve.

In this edition
At p. 125 · Passage 1 Pratum becomes “meadow,” while the Latin oracle’s “primal meadow” at p. 124 · Passage 3 is given in its own newly translated verse. The repeated meadow imagery should not obscure that these are different textual voices: quoted oracle and Vaughan’s commentary. The modern rendering of “Rendezvous” as “meeting place” similarly clarifies a function without supplying a physical address.
“Night of the body” keeps the genitive in Nox Corporis. Replacing it by “dark body” would turn a relation into a property of a single object and blur why it can share a referent with “region of light.” “Embodied” renders “incorporated” explicitly. Together these choices make the passage intelligible while leaving open what Vaughan does not name: the determinate natural subject or location he thinks the qualified practitioner can discover.
Historical forms and local uses: Principale pratum — primal meadow beneath the ascending powers in the cited oracle (p. 124 · Passage 3); Regio Lucis — region of light: the secret universal place of incorporation (p. 125 · Passage 1); Nox Corporis — night of the body: another perspective on that same mediating region (p. 125 · Passage 1); Pratum — meadow of the Ideas (p. 125 · Passage 1); Rendezvous of all Spirits — meeting place where descending Ideas become embodied (p. 125 · Passage 1); Region of Light — region to be known through the magicians’ claimed demonstration (p. 127 · Passage 1).
Rendezvous
The military or social word for an appointed meeting place is applied to all spirits at the point of incorporation. It stresses convergence: many arriving powers share a reception. The modern “meeting place” is explanatory, but the historical word also preserves the vividness of Vaughan’s gathering image.
Historical forms: Rendezvous — meeting place for the spirits (p. 125 · Passage 1).

Incorporate — incorporated
Ideas become “incorporated” as they descend into the dark world. The participle marks the passage into body, not the extinction of their relation to their source. The next sentences explain the cost of this reception: spirits acquire the impurities of the elemental matrix. That consequence is stated at p. 125 · Passage 2.
Historical forms: incorporated — given bodily existence (p. 125 · Passage 1).

Treasure — Treasures
The reader is invited to enter the region’s treasures before the universal subject appears. The word links knowledge to the sanctuary and treasury imagery used elsewhere without identifying the treasure simply as gold. What is promised here is understanding invisible things and their natural reception.
Historical forms: Treasures — hidden knowledge or powers associated with the region (p. 127 · Passage 1).
