Meaning

Unctuous humidity and moist unctuous vapour are descriptions of the philosophical twofold Mercury. The adjective conveys an oily or rich moisture, but the passage's own definition is relational: unctuous humidity is sulphureous Mercury, Mercury with philosophical sulphur.

Use in the book

The expressions occur in the compact equivalence-chain of p. 54. They follow man and wife, working and suffering, Rebis, twofold Mercury and ensouled Mercury. The moist unctuous vapour is then called the proximate matter of all metals. These predicates unfold what the single natural subject contains; they do not direct the reader to replace it with an independently chosen oil or vapour.

The phrase is especially useful because it joins properties a bare rendering “Mercury” might conceal. Moisture is inseparable here from the sulphureous and ensouled character of the pair. The number two describes an internal complementarity, while “all metals” preserves the claimed universality of its generative relation.

The immediately following triad and elements confirm the setting. All these analyses remain in one natural subject. The humidity is consequently one descriptive route into the same constitution, not an additional ingredient outside it.

Translation in this edition

“Unctuous” preserves the material suggestiveness of vnctuosus. The source does not name a modern oily substance, and “vapour” should retain its place within the philosophical description.

Source note

The p. 54 wording is a definitional chain rather than a recorded sequence of laboratory observations.
