Theurgia, or the Mysteries of Egypt

Attributed here to Iamblichus, this work belongs to the Neoplatonic tradition of theurgy, the ritual means by which the soul seeks union with divine powers. Its historical importance lies in its defense of sacred rites and symbolic correspondences, and readers will find discussions of ritual practice, divine mediation, and the spiritual structure of the cosmos.

Iamblichus (c. 245–c. 325 CE) was a late antique Neoplatonist philosopher whose writings profoundly influenced later mystical and theurgical traditions. His work On the Mysteries is a key text for understanding ancient theurgy, ritual practice, and the philosophical defense of divine communion.
