Historical Definition
Calx Veneris is verdigris.
Meaning
The definition gives the intended material directly. It is more reliable to follow that explicit identification than to translate the planetary name in isolation and stop there. Almizadir and Ziniar provide other routes into the verdigris vocabulary.
Chrysocolla is described as a green earth like verdigris, which is a resemblance rather than the same direct equation. Comparing the entries makes the difference between “is” and “like” useful. Their shared colour language does not, by itself, establish identical material composition.
