Iamblichus’s De Mysteriis

Record summary

Iamblichus’s De Mysteriis presents a defense of Egyptian and Chaldean theurgy against Porphyry, explaining ritual symbols, divine descent, possession-like phenomena, prayer, and the soul’s ascent. It is especially relevant to comparisons involving visionary states because it distinguishes divine manifestation from ordinary imagination and argues that ritual efficacy depends on the gods rather than human technique alone. The work is philosophical-theological argument, not a neutral case report. Its authorship, date, manuscript history, and terminology are well studied, but interpretation of its experiential claims remains contested. This is an AI-recalled lead.
