Meaning

Crocus literally names saffron, but in these metallic contexts it names a coloured preparation rather than the plant. The accompanying metal or planetary designation specifies the relation: Mars for iron, Venus for copper, Sun for gold. The word alone does not establish an identical modern composition for each product, nor does “crocus” guarantee an identical process.

Use in the book

Book V first treats crocus through the mortification of iron and steel. It gives two preferred approaches and evaluates the second as partly superior and less costly in labour and expense. A following paragraph acknowledges other materials that also yield crocus, but excludes those routes from medicine and assigns them only to alchemy. The important lexical point is that a shared product-name does not erase differences of process or permitted use within the author's system.

The copper discussion calls burnt copper crocus of copper and later uses the name crocus of Venus. This pairing joins an ordinary metal name, a planetary name and a preparation name. The author again compares alternatives and strongly prefers the one just described. Those judgments should remain attributed to him; they are not modern recommendations.

Gold's crocus appears in a list of arcana rather than receiving a full local description. It belongs beside gold's tincture, quintessence, resin, vitriol and sulphur. The author refers elsewhere for much of that material, then treats two arcana said to have been omitted. The references to other books do not make those books part of the present evidence. Finally, the marginal label “crocus of Lead” accompanies a paragraph about a yellow lead preparation. Its colour helps explain the naming field, but it should not be turned into a claim that every crocus is the same shade. Historical margins add useful terminology without supplying an independent chemical identity.

Translation in this edition

Note 40 explains the saffron-derived preparation name and distinguishes it from the culinary plant. Note 44 records loose punctuation around the alternative extraction associated with wine spirit. English Mars, Venus and Sun names must remain linked to their named metals without suppressing the source's planetary language.
