The Six Keys of Eudoxus - Tarl Warwick - Bog

The Six Keys of Eudoxus is a short but important manuscript within alchemy. Ascribed to an ancient philosopher, it dates to the Renaissance and describes a simplistic set of methods by which alkahest and the philosopher's stone can be made. Combining practice with theory, it is meant to make the process of alchemy easier for the student, so many similar materials being so highly symbolic and richly veiled with metaphor.
