Coelum Terrae

Magnesia

An inherited name for the philosophical subject. Red and white magnesia refer to appearances discussed in the description of the chaos. Neither the modern magnesium element nor an ordinary commercial substance should be substituted solely because the names resemble one another. See the historical passage.

Matrix

A receptive place or condition in which a seed can be held and developed. The word draws on the womb but extends to universal Nature and the place where spirits become embodied. Its meaning must be read with the particular scale of the argument. See the historical passage.

Medicine

The perfected subject Vaughan and his authorities describe as restoring corrupted natures. The quoted five-gate account distinguishes an earlier universal medicine from a final operation directed to metals. These therapeutic powers are historical claims, not assurances supplied by the edition. See the historical passage.

Mercury

A shifting philosophical name for the universal or mediating subject, linked to water, interpretation, motion and generation. Vaughan sometimes compares it with common quicksilver but does not thereby erase the distinction between a philosophical principle and an ordinarily named metal. See the historical passage.

Middle Nature

An intermediate substance or condition linking extremes. Water mediates between an originating darkness and formed creatures in one argument; later, shared elemental qualities explain local mediations. The word middle names a relation rather than one unchanging material identity. See the historical passage.

Natural Fire

Heat or active power understood through Nature’s living operations. Vaughan also distinguishes an externally prepared fire from the inward fire of chaos. A reader must ask which relation is meant instead of assuming that every mention names the same flame. See the historical passage.

Nature

The created order, its productive power, or the personified teacher who speaks through cited philosophical voices. Nature’s freedom and delight in varied forms supply Vaughan with a model of action independent of fashionable approval. These senses cooperate without being identical. See the historical passage.

Negative Theology

Speech about the divine source that refuses to define it by the properties of created things. Vaughan’s discussion of nothing invokes this approach; its nothing is not the simple nonexistence he expressly rejects. See the historical passage.

Patient

That which receives an action. The universal patient is first matter, created by the universal agent and receptive to its pattern. The historical term is not restricted to an ill person receiving medical care. See the historical passage.

Projection

The fifth gate in the extended testimony voiced by Nature, said to concern metals. It follows knowledge of the matter, preparation, fire and multiplication. The word is historical technical vocabulary here, rather than a modern psychological diagnosis. See the historical passage.

Putrefaction

A form of corruption or opening placed before a new generation. Vaughan’s account requires an appropriate natural dissolution of the compound, distinguished from violent destruction. Its place in a larger sequence is essential to its meaning. See the historical passage.

Quintessence

A fifth or sustaining essence. Vaughan criticises the name when it obscures the spirit of the living God, yet later calls the spirit of peace the true eternal quintessence. His use is deliberately theological and context-dependent. See the historical passage.

Reduction

A bringing back. The text contrasts destructive reduction into elemental extremes with a vital reduction into the middle seed from which a body was formed. The same general word can therefore name opposed outcomes. See the historical passage.

Region of Light

The secret universal region where descending ideas or spirits receive embodiment, described through a meadow, garden and bodily night. Vaughan tells readers to seek experiential knowledge of it; the text does not supply an independently established geographical location. See the historical passage.

Seed

The generative composition drawn by Nature from the elements, historically also called sperm. It is neither the separate elements nor the completed creature. Vaughan uses the relation across scales, so the word is not always restricted to human or plant reproduction. See the historical passage.

Sulphur

A philosophical term for an active, fiery or colouring principle in several descriptions, including the red and white sulphurs whose union depends on suitable heat. Its referent cannot be assumed to be common brimstone at every occurrence. See the historical passage.

Virgin Milk

An inherited name for the thick white water associated with the philosophical subject. It appears both in Vaughan’s personification and in the authorities’ lists of names. The maternal image participates in an argument about nourishment and generation. See the historical passage.
