The Magus; or Celestial Intelligencer | A Complete System of Occult Philosophy

Books I–III | Natural Magic, Celestial Forces, and the Legacy of the Adepts

A cornerstone of Western occult tradition, The Magus by Francis Barrett is a masterful synthesis of magical philosophy, ancient science, and esoteric lineage. First published in 1801, this three-part compilation remains one of the most important and accessible grimoires in the English language—uniting wisdom from Agrippa, Paracelsus, and other ancient sources into a single, visionary system.

Book I – Natural Magic

Barrett begins with the fundamental principles of occult science: the hidden virtues of stones, herbs, animals, and elements. This section explores the correspondences between nature and spirit, alchemy, talismans, and the animating forces that bind the material and spiritual worlds.

Book II – Celestial Magic

Here, Barrett moves into astrology and the celestial mechanics that influence fate, character, and magical potency. He outlines planetary intelligences, star influences, magical squares, and ritual timing—presenting a complete system of astrological magic drawn from ancient and medieval traditions.

Book III – The Biographies of the Adepts

In this final volume, Barrett curates short biographies and bibliographies of the great magicians, philosophers, and alchemists of antiquity—Zoroaster, Hermes Trismegistus, Apollonius, Roger Bacon, Agrippa, Paracelsus, and many more. Their lives, works, and mysteries are preserved as a tribute to the lineage of magical wisdom.

Together, these three books form a complete esoteric education: from the secrets of nature and the heavens to the memory of those who carried the torch of hidden knowledge through the ages. This audiobook is a must-have for any student of the occult, ceremonial magic, or the Western mystery tradition.
