《罗马帝国衰亡史》的开头：
On the death of that emperor his testament was publicly read in the senate. He bequeathed, as a valuable legacy to his successors, the advice of confining the empire within those limits which nature seemed to have placed as its permanent bulwarks and boundaries; on the west the Atlantic Ocean; the Rhine and Danube on the north; the Euphrates on the east; and towards the south the sandy deserts of Arabia and Africa.

似乎与明太祖朱元璋划定朝鲜、日本、安南等为不征之国异曲同工？
