At a Glance
- The wordMinerals are one of the three highest kinds of compound. Metals receive special consideration because the author attributes to them a concealed principle and qualified kind of life.
- In the bookThe text distinguishes ordinary existence from life in the proper sense, then explains why metals, especially perfect ones, occupy an exceptional position within the mineral class.
- In this edition“In some measure” and “especially” prevent the qualified account of metallic life from becoming an unconditional claim about every stone or mineral.
- A place to readCanons 154–156 together with 172–174, where ordinary stones, gems, and metals receive different accounts.
Meaning
The vocabulary begins with a class, Mineralia, and a privileged group within it, Metalla. Canon 154 places minerals, plants, and animals in a hierarchy of existence. Canon 155 then states the received view that minerals merely exist rather than live, before allowing a qualified attribution of life to metals. The local question is what kind of activity or hidden principle justifies that qualification.
Life’s concealed presence is distinguished from currently observable motion. A hard body can restrict a formal spirit, so that the absence of outward activity does not, on the author’s account, prove the absence of all formative power. Conversely, not every mineral receives the same excellence simply by being dense or enduring.
Use in the book
Canon 154 gives minerals generation in earth, plants roots in earth and water, and animals birth and feeding in earth, water, and air. Air is nevertheless the principal life-food of all. The classification therefore does not assign each class a sealed region with no communication from the others. It describes dominant modes of existing and developing within Nature’s general exchange of powers.
Canon 155 introduces the qualified case for metals. The first reason is reproductive analogy: their generation involves a kind of intercourse and the mingling of male and female seeds, identified as sulphur and mercury. Circulation, purification, fermentation, and subtle mixture describe Nature’s long preparation of the metallic body. The lexicon need not convert that conceptual sequence into a procedure; what matters for the argument is the analogy between metallic formation and the joining of generative powers in living beings.
Canon 156 supplies a second reason. Especially in perfect metals, an implanted fire from heaven lies concealed as a life-principle. The hard rind dulls its activity, and the author compares it to an enchanted treasure. Release is associated with philosophical dissolution and the artist’s subtle ingenuity, after which the concealed spirit is said to unfold through a movement of growth. This is a claim about the latent possibilities attributed to the metal, not an ordinary observation that every metal visibly reproduces on its own.
The later comparison with other mineral bodies sharpens the distinction. Canon 172 portrays ordinary rocks and stones as formed more by the external cooking of earth and water than by a true elemental mixture. Their form is feeble and they are insensible. Canon 173 expressly says precious stones and gems require a different account: their bodies are imagined as pure enriched dew and their forms as deriving from heavenly and solar sources. The formula of “congealed tears” is the author’s poetic description of celestial influence, not a claim to a separate substance named tears.
Canon 174 returns to metals with the apparent paradox of subtle formation and gross result. Their extremely fine mixture produces an unusually compact, heavy, motionless body. Yet repeated natural refinement makes that matter receptive to the Sun’s and heavens’ resources, especially in perfect metals. Nature is again a potter preparing a body worthy of an excellent form. The greater density of the result does not imply a cruder formation process.
The closing prison image restates the distinction between restricted operation and absent power. Formal spirits remain enclosed within a hard rind until liberated by what the author calls the philosophers’ fire. Its promised culmination belongs to the text’s alchemical horizon. It should not be generalized into a verified method or identified without evidence with ordinary combustion. Across these passages the lexical point is a graded account of existence: ordinary stones, gems, and metals are compared by formation, mixture, receptivity, and the range of their formal powers.

Translation in this edition
Canon 155’s creduntur is “are believed,” introducing the received classification, while dici possint permits a qualified alternative. vitâ quodammodo praedita means endowed with life “in some measure,” and canon 156’s potissimùm singles out perfect metals especially. Neither term should disappear in a summary. In canon 174 the description of body as motionless coexists with the presence of formative spirits; this is the author’s distinction between confinement and nonexistence. The terms “philosophical dissolution” and “philosophers’ fire” are retained as historical vocabulary without supplying a chemical identification or actionable recipe.
