Constantinople - \'New Rome\'?

[Macedon]

The term "Nea Rome" in TLG appears about 400 times (!) in official and unofficial contexts. It was certainly used officially and I very often found it as part of religious titles where it appears as "office (episcopos/archepiscopos/patriarch etc) of Constantinople (,) New Rome"

"πατριάρχης Κωνσταντινουπόλεως νέας Ῥώμης"

"Ἀθανάσιος ἐλέω Θεοῦ ἀρχιεπίσκοπος Κωνσταντινουπόλεως Νέας Ῥώμης καὶ οἰκουμενικὸς πατριάρχης"

"Παρθένιος ἐλέω Θεοῦ ἀρχιεπίσκοπος Κωνσταντινουπόλεως Νέας Ῥώμης καὶ οἰκουμενικὸς πατριάρχης"

" τῶν πρεσβείων τῆς ἁγιωτάτης ἐκκλησίας Κωνσταντινουπόλεως Νέας Ῥώμης"

often there is a comma between C and NR but I would not see it as a means of differentiation.

"Φώτιος, ἐπίσκοπος Κωνσταντινουπόλεως, νέας Ῥώμης"

(of course I can give you sources guys, but I do not see there is a point at the moment, there are really too many.)

As for the Instanbul question, it is my opinion that because there was a lot of Dorian spoken in the area (they differentiated between Doric and Ionian pronunciation even during the Byzantine times, it is not true that everyone talked "koine Greek"), it would often be "eis tan poli" (tan instead of ten) that would read "is tan poli".
