A place to read. The historical definition below, 1650 dictionary, unnumbered definition page 25; facsimile PDF page 353.

Historical Definition

Henricus rubeus is the colcothar of vitriol.

Meaning

The definition leads to Colcothar rather than describing a person suggested by the name. Its vitriol qualifier belongs to the material identification. No separate recipe or property is supplied under this heading.

Use in the Book

Colcothar is defined as calcined vitriol or the caput mortuum of oil of vitriol. Sal Calcotharinum is a salt made from that material. The cross-references distinguish the named residue from a salt subsequently associated with it. Henricus rubeus belongs to the first naming relationship.

Places to Read

Colcothar. Vitriol named through calcination or through the residue of its oil.

Sal Calcotharinum. A salt derived from vitriolic colcothar.
