At a Glance

The word. An iron or steel preparation named through crocus vocabulary.

A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 13; facsimile PDF page 341.

Historical Definition

Calx Martis is crocus of steel or iron.

Meaning

The historical definition offers steel and iron as the material family and crocus as the prepared identifying term. It does not state a single procedure or modern composition. Preserve both material alternatives, rather than choosing one merely because a later recipe is more familiar.

The neighbouring Calx compounds show why the complete name matters. Each has its own gloss, and their products should not be collapsed into one generic ash. A passage describing the preparation, colour or treatment of iron can clarify the particular crocus intended.

Places to Read

Hadid. A dictionary name for iron.

Calx Iovis. A tin-related calx name glossed as a spirit.

Calx Solis. Gold distinguished by calcination.
