  Dionysius, or Pseudo-Dionysius, as he has come to be known in the contemporary world, was a Christian Neoplatonist who wrote in the late fifth or early sixth century CE and who transposed in a thoroughly original way the whole of Pagan Neoplatonism from Plotinus to Proclus, but especially that of Proclus and the Platonic Academy in Athens, into a distinctively new Christian context.
