The Mirror of Alchemy

"The Mirror of Alchemy," attributed to Roger Bacon, is a compact medieval treatise that summarizes key alchemical doctrines and procedures in a practical, didactic style. Historically significant within the Latin alchemical tradition, it offers readers an accessible account of elemental theory, the preparation of substances, and the broader philosophical aims of alchemy.

Texts attributed to Roger Bacon, the 13th-century English philosopher and Franciscan friar, became important in later occult and magical traditions, especially in alchemical, astrological, and experimental writings circulated under his name. Although many such works are pseudepigraphic, the Bacon attribution helped confer authority on a substantial body of esoteric literature.
