Rendered Faithfully for the Modern Seeker

Summa Perfectionis, or “The Sum of Perfection,” is widely regarded as the most influential alchemical treatise of the Latin Middle Ages. Attributed to the legendary Geber (Jābir ibn Ḥayyān)—an 8th-century polymath whose name became synonymous with practical alchemy—this work became the foundational blueprint for countless philosophers, mystics, and early scientists across Europe and the Islamic world.

In this edition, drawn from a carefully corrected Vatican manuscript, the reader is invited into a world of fire and transformation, subtle vessels and sublime theory. With striking clarity, the text reveals the precise methods, materials, and spiritual orientations of the alchemical art as understood by its most revered master.

This is not a symbolic fantasy, nor is it a scholarly-critical edition. It is a faithful rendering of the original Latin, presented in accessible, contemporary English—preserving the structure, tone, and intent of the source, while offering clarity for modern readers. Technical and initiatory in nature, the work carries both practical detail and hidden spiritual meaning.


This edition includes:

• The complete text of the Summa Perfectionis Magisterii
• The original preface from the Vatican edition
• Appended treatises including the Book of Investigation, the Testament of Geber, and more
• Translation notes, modern formatting, and restored structure

Whether you are a scholar of Hermeticism, a practitioner of esoteric arts, or a curious reader drawn to the roots of Western mysticism, this work is essential. Its influence echoes through Paracelsus, Isaac Newton, and the Rosicrucians. It is not merely a book—it is a cornerstone of the alchemical canon.
