Byzantium
edit- Roderick Beaton, The Greeks [1], page 289:
In the language of today, the Greek-speaking Roman Empire after the death of Heraclius in 641 had turned into the Byzantine. Out of this process a new Greek civilisation was emerging.
- Arnold Toynbee, The Greeks and their heritages [2], page 80:
In Byzantine Greek parlance, Rhomaioi cam to mean, not Latin-speaking Romans, but Greeks who were Eastern Orthodox Christians.
