I often wondered what they thought about who pseudo-Denys really was. Here's the answer:
"Of course, I don’t believe that the writer of The Divine Names, Mystical Theology, etc. is a Pseudo-Dionysios 5th Century writer coming from historical textual criticism from 19th century German scholars, but rather St. Paul’s actual convert in Acts as we hymn in the liturgy. That’s a seperate matter though, but it is an important one.
Photios"

I guess he must have taught Proclus then, or else close textual parallels are purely coincidental. And yet its us latins that have been corrupted by Platonism.
