[INJECT: I apologise for the hiccup in Blogspot like 8-11 AM MST. I don't know what happened; I don't believe I was HAX0RD. Might be a DNS problem at Google.]
We're doubling-up today. I wish to discuss a source for the Paradise here Palladius' vol. 1.
Budge 1.45 talks one sancta Juliana, of Caesarea-in-Cappadocia. Juliana transmitted from Symmachus the "expositor" (= translator), a collection of... these things
.
Straightaway this supports Jerome and Eusebius that Symmachus was Christian, against Epiphanius.
On checking, the author of that Juliana anecdote seems to correct her: that the collection was in Origen's handwriting a little later (Origen had made enemies in his home Alexandria, whence he'd fled AD ~230). But we might posit a harmony: Origen 'an Symmachus. Origen had done the same for the Hexapla.
Chapter 1.34 itself concerns the time of Athanasius who only really gets going from AD ~320, laying the antiArius case before Nicaea. That chapter is here at 1.34 discussing a 20 year old virgin, nameless, who hid Athanasius from "Constantine the Less". Constantine II's full reign AD 337-40 is possible; the editor Budge prefers however Constantius II, who ruled the East earlier. She is 70 at the time of writing, and still won't divulge her name - suggesting the imperium of Valens, which seems (to me) early, for Palladius. Whoever was the author, he thereby makes the case for Juliana as this virgin's predecessor in True Faith.
As to the content of that collection, there is no way a man of Valens' imperium had met Juliana in the AD 240s. I note that 1.46 moves from Cappadocia to Galatia. So (pseudo?)Palladius is, I think, roaming the Anatolian hinterland looking for rare books and stories AD 360s.
I suggest, behind 1.35-46, Origen's abridgement of Symmachus geared toward holy women of lower Egypt, which Juliana - a holy woman elsewhere - commissioned. The Paradise collects much content about holy women, mostly virgins, from 1.34f; in here, besides the oral account commencing it, is lore interpolated from Hippolytus of Rome; but most is later and Egyptian.
