Ignis leonis

Elements principles and the natural world · A Chymical Dictionary

At a Glance

The word. A fire name directly identified with the element.

In the book. Ignis Persicus is a burning ulcer, and Ignis pruinus adeptus is a prepared quintessence of vitriol.

A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 26; facsimile PDF page 354.

Historical Definition

Ignis leonis is the element of fire itself.

Meaning

The definition supplies an explicit elemental identification. It does not name a particular furnace, fuel or medicinal preparation. “Itself” emphasises that the gloss directs the reader to the element rather than explaining the phrase through a separate product.

Use in the Book

Ignis Persicus is a burning ulcer, and Ignis pruinus adeptus is a prepared quintessence of vitriol. These neighbouring fire names have different subjects. Exact qualification is therefore essential: the shared opening Ignis does not make all three expressions refer to the same kind of thing.

Places to Read

Elementum. The elemental domain described through corruption, transience and change.

Ignis Persicus. A medical condition named through burning heat.

Ignis pruinus adeptus. A vitriolic quintessence qualified by rectification with tartar.
