Historical definition

Ilech crudum is a composition of the first matter of the three first principles.

Meaning

The phrase connects a composition with first matter and with three first principles. The entry does not name the principles in this sentence, but the dictionary’s Iliaster definition explicitly lists Sulphur, Mercury and Salt. That parallel supplies an internal guide to the terminology.

“Composition” should remain visible. The text is speaking about a relation of constituent principles, rather than simply using Ilech crudum as another unqualified name for any first matter.

Use in the book

Ilech primum receives the shorter gloss first principle. Ilech magnum concerns a medicine’s ascendant or star, while Iliaster introduces a fourfold account alongside the three principles. Keeping these definitions distinct allows the reader to follow the change in scale and qualification across related names.

In this edition

The modernised definition retains the compressed historical construction. It does not impose a modern list of chemical ingredients upon the three principles.
