The Mirror of Alchimy

A compilation of alchemical treatises sets out definitions of the art, explains its two basic principles—mercurial and sulfurous substances—and presents a theory of how metals arise and aspire toward gold. It offers procedural guidance for selecting and preparing the matter for a philosopher’s stone or elixir, includes commentary on the Smaragdine Table and allied aphorisms, and contains a discursive essay on the relation between art and nature alongside practical chapters on laboratory operations such as decoction, fixation, purification, and methods for transmutation.
