Episode 141: Brian Alt on Sacred Materials, Divine Names, and Subtle Physiology in Iamblichean Theurgy

We explore the practical side of Iamblichean theurgy with Brian Alt. The discussion follows the title of Alt’s PhD thesis – Correspondences and Invocations: Sacred Materials, Divine Names, and Subtle Physiology in Iamblichus – in exploring the De mysteriis looking at three main thematic clusters: divine materials and occult properties, the theory of effective/divine language, and Iamblichus’ theory of the soul-vehicle/subtle body.

Expect a wide-ranging discussion, exploring many parallels between Iamblichean rituals and those found in Greek ritual papyri and Hermetica, and making a strong case for much more genuinely-Egyptian material in the De mysteriis than is normally credited in scholarship. Lovers of addressative ritual will find much to love in this interview.

Interview Bio:

Brian P. Alt is an independent teacher and researcher specializing in ancient languages, the intersections of philosophy and religion in Græco-Roman Egypt, and the history of magic. His PhD (2020) focused on Iamblichean theurgy and its interaction with Greco-Egyptian ritual practice. His forthcoming book on the Græco-Egyptian magical papyri (PGM) will be available to pre-order soon on the InterlinearMagic.com website.
