While consecration is an important kind of ritual (or element of complex rituals), it only begins to be thoroughly theorized by philosophers late in antiquity. The two most important figures in this connection are the Neoplatonists Iamblichus and Proclus. However, their viewpoint must not be mistaken for the only perspective on how consecration functioned. Many non-theoretical sources, as well as the theories found in later philosophers, imply quite different understandings of the practice and its effects.
