Book excerpt: This volume examines the discussion of the Chaldean Oracles in the work of Proclus, as well as offering a translation and commentary of Proclus’ Treatise On Chaldean Philosophy. Spanu assesses whether Proclus’ exegesis of the Chaldean Oracles can be used by modern research to better clarify the content of Chaldean doctrine or must instead be abandoned because it represents a substantial misinterpretation of originary Chaldean teachings. The volume is augmented by Proclus’ Greek text, with English translation and commentary. Proclus and the Chaldean Oracles will be of interest to researchers working on Neoplatonism, Proclus and theurgy in the ancient world.
