First published in 1906 as part of Thrice Greatest Hermes , G. R. S. Mead’s translation of the Corpus Hermeticum remains a cornerstone of Hermetic literature and Western esoteric tradition. The Hermetic writings, attributed to the legendary sage Hermes Trismegistus, were composed in Greek between the first and third centuries CE and preserved as dialogues of divine wisdom. They explore the nature of God, the creation of the cosmos, the workings of the divine intellect, and the path of the human soul toward enlightenment and immortality. For centuries, the Hermetic texts were regarded as sacred wisdom, influencing philosophers, mystics, and scientists alike. During the Renaissance, thinkers such as Marsilio Ficino and Giordano Bruno believed they were reading the most ancient theology, older even than Plato and Moses. These writings shaped the study of alchemy, magic, astrology, and mystical philosophy, providing a foundation for Rosicrucianism and later occult traditions. Mead’s edition was the first comprehensive and reliable English translation, making the Hermetica accessible to both scholars and spiritual seekers. Mead was not only a classical scholar but also a Theosophist deeply engaged with comparative religion and the study of Gnosticism. His translation and commentary situate the Hermetic writings within their cultural setting in late antiquity, where Egyptian religion, Greek philosophy, Jewish mysticism, and early Christianity intersected. The result is a body of work that bridges the gap between ancient theosophy and modern seekers of hidden wisdom. This edition of the Corpus Hermeticum is indispensable for readers of Hermetic philosophy, esoteric traditions, Gnosticism, Neoplatonism, and mysticism. It belongs beside the Divine Pymander , the Gnostic gospels, the writings of Plotinus, and the alchemical treatises of Paracelsus. For students of philosophy, religion, or the occult, it provides essential context for the development of Western thought. For practitioners and seekers, it remains a living guide to spiritual rebirth, divine knowledge, and the mystery of the cosmos. More than a historical text, Mead’s Corpus Hermeticum continues to inspire, challenge, and illuminate across the centuries.
