Historical definition

Cauda vulpis rubicundi is minium of lead.

Meaning

The historical definition supplies a direct material anchor for the figurative name. It identifies the substance through minium and lead rather than leaving the image open to unrestricted symbolism. The entry does not explain why the tail expression was chosen or state a process.

Calx Saturni gives minium under another qualified name, while Azemasor records minium or cinnabar as alternatives. Linking these entries helps a reader compare names while preserving the different certainty and scope of each equation.
