Libellus de Alchimia

Libellus de Alchimia, attributed to Albertus Magnus, is a seminal exploration of medieval alchemical practices, reflecting a blend of observational precision and philosophical inquiry. Translated into English from the Borgnet Latin by Sister Virginia Heines, a chemist with a deep appreciation for historical science, this text offers readers a rare glimpse into the scientific landscape of the late thirteenth and early fourteenth centuries. Whether penned by Albert himself or an admirer of his methods, the treatise exemplifies the didactic style associated with his works. It aims to provide practical guidance to alchemists while embedding their pursuits within a framework of ecclesiastical wisdom, opening with the assertion that "All wisdom is from the Lord God."

This meticulously organized text unfolds across fifty-seven concise chapters, addressing both theoretical and practical aspects of alchemy. It introduces readers to the tools, techniques, and materials of the medieval alchemical laboratory, from sublimation and calcination processes to the elusive quest for the philosopher's stone. Remarkably devoid of magical incantations, the work emphasizes experimentation and empirical observation, reflecting Albertus Magnus' broader contributions to natural science. While the conclusions may not align with modern scientific understanding, Libellus de Alchimia foreshadows significant discoveries and embodies the earnest pursuit of knowledge that characterized its time. This translation not only preserves the historical charm of the original but also illuminates its relevance to the evolution of scientific thought.
