Historical definition
Cydar is Jupiter.
Meaning
The definition supplies Jupiter and nothing more. Elsewhere the dictionary explicitly identifies Iupiter as tin, so the reader has a route from this unfamiliar word to the book’s metal vocabulary. That route depends on the second entry, rather than on a further claim printed here.
Use in the book
Calx Iovis names a spirit of tin, while Lato is described through copper and lapis calaminaris. These examples remind a reader to distinguish a planetary name for a metal from a preparation or combination involving it. Cydar itself does not describe a preparation.
