The Chaldaean Oracles of Zoroaster presents the enigmatic body of theurgic poetry traditionally associated with Zoroaster and the Chaldaean sages, a corpus surviving chiefly through fragments and testimonia preserved by later Neoplatonists. Its densely symbolic style—invoking divine intellect, cosmic fire, emanation, and ritual ascent—belongs to the late antique synthesis of Persianizing religious authority, Greek metaphysics, and sacramental practice. Rather than a continuous narrative, the work offers aphoristic revelations whose obscurity is integral to its vision: knowledge is achieved through purification, contemplation, and participation in the divine order. Its literary and intellectual afterlife extends from Porphyry and Iamblichus to Byzantine commentators and Renaissance Platonists, who treated it as a foundational document of ancient wisdom. The anonymity surrounding this title is itself historically significant. The oracles were attributed in antiquity to Zoroaster, but modern scholarship generally connects their composition with Julian the Theurgist and his circle in the second century CE. Their authors or transmitters worked within an era fascinated by recovering primordial revelation, and they shaped older Iranian-sounding traditions through the conceptual vocabulary of Platonism. The resulting text reflects the religious experimentation and philosophical ambition of the Roman imperial world. This volume will reward readers interested in Neoplatonism, comparative religion, esotericism, and the history of Western metaphysics. It is best approached not as transparent doctrine, but as a challenging poetic-theological artifact whose images illuminate how late antiquity imagined the soul's return to its transcendent source.
