“We have from the sixth century [AD] a much more elaborate classification of the civilian part of [Byzantine] society into ten groups, namely: 1. The clergy; 2. The judiciary; 3. Counsellors (senators?); 4. Those concerned with finance; 5. Professional and technical; 6. Commercial; 7. Those concerned with the provision of raw materials; 8. Subordinates and servants; 9. The useless (in other words, the old, the infirm and the insane); 10. Entertainers (charioteers, musicians, actors).” – Cyril Mango, Byzantium: The Empire of New Rome
