  Sun metaphor ... the photon as "god particle"
  "... the divine irradiation shines upon [all places in the universe] from the outside, just as the sun illuminates every object from without with his rays. Hence, as the light encompasses the objects that it illuminates, so also the power of the gods comprehends from without those that participate of it. In like manner, also, as the light of the sun is present in the air without being combined with it -- and it is evident that there is nothing left in the air when the illuminating agent is removed, although warmth is still present when the heating has entirely ceased -- so also the light of the gods shines while entirely separate from the objects illuminated, and, being firmly established in itself, makes its way through all existing things."
  
  “For truth is essentially coexistent with the gods as light is coexistent with the Sun.”
  What happens to truth when the sun burns out?

  Theurgy is the ritual practice of the ancients who believed in the divine One that transcends the earthly and materialistic as well as the metaphysical and profane. Pseudo Dionysius the Areopigate adapted these ritual beliefs for his brand of Christian Neoplatonism. This is all I can remember over the span of two undergraduate degrees.

  Really enjoyed this book. I wasn't sure if I would but it was a fascinating look into the beliefs of the ancient Greek world.
