Meaning
Gradus can mean a step in an ordered process or a degree of intensity. Book Seven uses both senses: seven principal stages of transmutation and differentiated degrees of fire. Their relation is practical, but they are not identical lists. The ladder supplies the literal image behind the ordered-stage sense; graduari and graduatum describe intensification or controlled adjustment. A reader should therefore ask whether a passage counts operations, ranks qualities, or regulates heat.
Use in the book
The first paragraph allows more than seven named operations while restricting the principal stages to seven. Subsidiary procedures are comprehended under calcination, sublimation, solution, putrefaction, distillation, coagulation, and tincture. This qualification makes the number classificatory: the appearance of extra operations elsewhere does not by itself contradict the sevenfold scheme.
Putrefaction exposes a more difficult ordering. It would deserve to be first because of its efficacy, yet is fourth in the sequence demanded by the mystery. The chain and ladder comparisons insist that changing the order destroys the work. Importance, explanatory priority, and position in the prescribed sequence therefore must not be confused. The captive released by a broken chain and the climber falling from a broken ladder dramatize dependence between steps.
Degrees of fire form a separate practical ordering. Book Seven describes several heat sources and media, each with its characteristic operation; Book Eight specifies four degrees within vegetable distillation. Book Eight also provides an expanded catalogue of separation procedures. These local classifications serve different purposes and should remain distinct rather than being forced into a universal seven-item chart. Across the discussions, knowing a degree means knowing what a given condition does to a particular material, not merely memorizing a number or assigning a modern temperature.
Places to read
- Book 7 · Transmutations · Passage 1Latin“septem praecipui” Seven are principal; other operations are subordinated to them.
- Book 7 · Transmutations · Passage 5Latin“sicut articuli in catena aut gradus in scala” Chain and ladder explain why sequence matters.
- Book 7 · Transmutations · Passage 14Latin“quilibet gradus peculiarem habet operationem” Degrees of fire have different effects.
- Book 8 · Separation · Passage 35Latin“quatuor gradus Ignis” The fourfold count is local to distillation.
Translation in this edition
“Stage” and “degree” differentiate local senses of the same Latin word. No measured temperature scale is supplied. The book’s classifications are preserved as historical operational distinctions.
