When I was in Ephesus the tour guide never once mentioned Greek or any reference to Byzantium. It was Lydians, Romans, Romans Lydians all the time. When I asked about that omission, she replied that that the "yunanis" and "romans" (meaning Byzantium) had contributed to the "rich fabric" of culture of Turkey. Of course never once was the significance of Christianity in Ephesus ever mentioned.
They have yet to find the icons. :-)
Neither did the Greek-speaking Roman citizens who lived in the eastern part of the Roman Empire. It was Western scholars in the 18th century who gave the name Byzantium to that part of the Roman Empire that survived in the eastern Mediterannean after the western part of the empire collapsed due to the invasions of Germanic tribes.
Perhaps the name change was intended to distinguish between the remaining Roman Empire in the east and the Holy Roman Empire that was established in the West by the Germanic kings. But as someone pointed out long ago, the Holy Roman Empire established by Charlemagne (roughly France and Germany, and greately reduced in size after his death) was neither Holy, nor Roman, nor an Empire.
But Byzantium also carries associations related to the word byzantine, meaning complex intrigue, cunning, and devious. This may be an unfair way of thinking about the Byzantine Empire.
Byzantium and the Holy Roman Empire are so ingrained in the diction of West Europeans and Americans that we are forced to use the terms or else risk being misunderstood. Obviously your Turkish guided didn't understand the Western usage or choose to ignore it.
Of course never once was the significance of Christianity in Ephesus ever mentioned.
That is rather unfortunate, particularly if the tourists were primarily Christian. But then the Turks did a rather thorough job of converting their Christian slaves to Islam, as well as slaughtering those Christians who refused to surrender as slaves. Did the guide mention that?
