Emperor Justinian I assigned to five sees, those of Rome , Constantinople , Alexandria , Antioch and Jerusalem , a superior ecclesial authority that covered the whole of his empire. The First Council of Nicaea in 325 reaffirmed that the bishop of a provincial capital, the metropolitan bishop, had a certain authority over the bishops of the province.  But it also recognized the existing supra-metropolitan authority of the sees of Rome, Alexandria and Antioch,  and granted special recognition to Jerusalem.   
In 1995, an established journal of classical scholarship, Classics Ireland , published punk musician's Iggy Pop 's reflections on the applicability of The Decline and Fall of the Roman Empire to the modern world in a short article, Caesar Lives , (Vol. 2, 1995) in which he noted "America is Rome. Of course, why shouldn't it be? We are all Roman children, for better or worse... I learn much about the way our society really works, because the system-origins - military, religious, political, colonial, agricultural, financial - are all there to be scrutinised in their infancy. I have gained perspective."
