Episode 76: The Chaldæan Oracles and Theurgy

[As in the last episode, all quotations are from the translation of Majercik (1989), and fragment numbers correspond to the edition of des Places (2003). Thanks to wikipedia for the above image.]

In this episode we look primarily at the fragments of the Oracles, seeing what we can piece together of the ritual practices outlined therein. Inevitably, a lot of comparative material is used from later Platonist theurges, since they tell us a lot more about theurgy (or their idea of theurgy) than the surviving fragments of the Oracles do. It is unclear how much of the material discussed in this episode was considered ‘theurgic’ in antiquity, but it is clear that all of it was discussed in the Oracles.

We break the subjects discussed down into headings:

  • Preliminaries (purification and stuff like that),
  • Invocations (κλῆσις, the summoning of a god or daimôn, the question of an esoteric corpus of Chaldæan voces magicæ, the fascinating figure of the δοχεύς, and the rites of binding and loosing),
  • Stuff (magical paraphernalia, especially the Wheel of Hekate, which may be the same thing as the iunx),
  • σύστασις (a practice attributed to the Chaldæans in a few sources, but well-known from the Greek magical papyri, which probably involved linking the soul of the practitioner with other powers such as daimones or souls of the dead to boost his power),
  • Scrying and Epiphany (we look at the extraordinary types of visions a Chaldæan practitioner can expect to see),
  • τελεστική (animation of statues, with some discussion of why a theurge might want an animated statue about the place)
  • ἀναγωγή (the practice of ascent of the soul, the reference to loosing the soul through inhaling in a comparative context with the Mithrasliturgie [see the following episode for more on this text], and the question of what the Chaldæan symbola and synthemata are), and
  • ἀπαθανατισμόs, Immortalization of the Soul (some introductory discussion of theories of lower and higher souls, toward a model of ancient immortalisation, which would seem to be the end-goal of theurgic ascent).

[Note: for an example of how theurgy plays out in modern, avant-garde esoteric saxophone composition, check out our interview with Randall Hall.]
