Episode 75: The Chaldæan Oracles

[Another SHWEP field-recording. Special thanks to the Dublin police-department and the seagulls for soundtrack]

[Corrigendum: we describe Porphyry’s de regressu animæ as extant; it is sadly extant only in fragments cited in Latin by St. Augustine]

The Chaldæan Oracles weren’t Chaldæan, nor were they oracles in the traditional sense – they were something else entirely. This hexameter poem, surviving only in fragments, outlines a Platonistic metaphysics incorporating an ineffable first principle (the Father, a.k.a. ‘the Abyss’), a complex hierarchical reality with a demiurgic Nous, and a number of crazy intermediate beings (time-deities like the Aiôn, iunges, synocheis, teletarchai, daimones au go-go, and much more). The Chaldæan universe is a densely-populated place full of immaterial and quasi-immaterial entities with both metaphysical and personal character: the gods are principles, the principles are gods.

Better still, this poem also gave mysterious details as to the ritual practices available for the adept to navigate this forest of entities in the quest for ascent and immortalisation: the Chaldæan Oracles are, in fact, the locus classicus of the ancient practice of theurgy, ritual practices (many of them familiar from magical texts found among the Greek Magical Papyri) reframed with philosophic/metaphysical significance. ‘Magic’ isn’t just for making girls fall in love with you or cursing your enemies any more; now it has the highest possible goals – the philosophic ascent and salvation of the soul. Philosophic understandings of the importance of ritual would never be the same.

We discuss questions of authorship, the Nachleben of the Oracles – in Late Platonism, selected early Christian thinkers, and beyond – and the metaphysics/mythology of the Oracles. In the following episode we discuss the ritual practices outlined in the text for navigating this strange mythic/metaphysical landscape.

We use the translations of Majercik throughout the episode): Our first quote, fr. 1, on the ‘certain intelligible’, is from Damascius Dub. I, 54, 14-26, quoting Iamblichus’ work on Chaldæan Theology.The first god ineffable: fr. 37. ‘He’ has ‘wombs’: frr. 4, 28.
