Ordo Aurum Solis ("Order of the Gold of the Sun") is a Hermetic and Theurgic order founded in England in 1897 by George Stanton and Charles Kingold. It is a vehicle of the Ogdoadic Tradition, itself an important element of the Western Mystery Tradition. Ordo Aurum Solis is best known through the published works of two of its past Grand Masters, Vivian Godfrey and Leon Barcynski. Better known by their pseudonyms, Melita Denning and Osborne Phillips, the husband and wife team together authored many books (some reappearing in newer editions) that cover different aspects of magical practice, such as the Llewellyn Practical Guide to Astral Projection and Llewellyn Practical Guide to Creative Visualization, as well as their seminal work (reprinted in three volumes) outlining the philosophy and practices of Ordo Aurum Solis: The Magical Philosophy.
Despite a few similarities to the Hermetic Order of the Golden Dawn, some of its descendants, various Thelemic orders, and other groups stemming from the Rosicrucian revival of the 19th century, Ordo Aurum Solis represents a distinct and unique system of magical philosophy and practice based on the Ogdoadic Tradition
The Ogdoadic Tradition stems from the Mediterranean mystery religions of ancient Greece as well as the Theurgic practices of the priesthoods of Ptolemaic Egypt. Its signature symbol is the Eight-pointed Star of Regeneration, an emblem signifying the Regeneration of the Soul and Divine Inspiration. Its philosophy and practices appear in the works of early Hermetists and the teachings of the Neoplatonic schools of Alexandria, Apamea, and Athens in Late Antiquity. According to its initiates, the father-figure of the Tradition is Hermes Trismegistus.
