Gilbert Keith Chesterton,
The New Jerusalem — Chapter X: The Endless Empire
(1920)
“ In the East the civilisation lived on, or if you will, lingered on; in the West it died and was reborn. But for a long time, it should be remembered, it must have seemed to the East merely that it died. The realms of Rome had disappeared in clouds of barbaric war, while the realms of Byzantium were still golden and gorgeous in the sun. The men of the East did not realise that their splendour was stiffening and growing sterile, and even the early successes of Islam may not have revealed to them that their rule was not only stiff but brittle. ”
