menstruum mundi
The menstruum is the named medium associated with the sphere of Luna and said to have undergone repeated rectification.
- English renderings
- world’s menstruum
Meaning
Phrase.
The menstruum is the named medium associated with the sphere of Luna and said to have undergone repeated rectification. Its appearance follows the author’s explicit declaration of the limit of his experience. This position matters: the phrase participates in the continued explanatory account but should not erase that limitation. The historical term is preserved without identifying a modern chemical solvent or translating it into a recipe.

menstruum Mundi
Water as menstruum is the receptive medium in which generative processes occur and from which seed draws nourishment.
- English renderings
- menstruum of the world
Meaning
Phrase.
Water as menstruum is the receptive medium in which generative processes occur and from which seed draws nourishment. Air penetrates it and carries warm vapour through heat’s power. The term has technical solvent and reproductive associations, but the source itself identifies the world’s menstruum as water. Its occurrence does not authorize treating every later allegorical water as ordinary water.
