A few questions about the Byzantine Emperors

[Byzantine Prince]

The term Byzantine was used by contemporary scholars some times to describe what we call today "Byzantine" empire. Priscus, for instance, uses the term "historia Vizantinae" (Ιστορία Βυζαντινή) in one of his works. Of course this term was confined in space and time and definitely was not accepted by anyone besides some scholars (the officials and public talked about "The Roman Empire" and that's it).

That is interesting. 'Byzantine' is not simply a made up term, it is there to describe the cradle of power of the Eastern Roman Empire. Even though the name of the city was changed, everyone knew what it really was. History cannot be fully erased.

Ah, btw the latter should read Αρχιεπίσκοπος Κωνσταντινουπόλεως, Νέας Ρώμης, Οικουμενικός Πατριάρχης

I bet they still use polytonic. You know those old-school priests.
