Famous quotes containing the word corps:
“Ce corps qui s’appelait et qui s’appelle encore le saint empire romain n’était en aucune manière ni saint, ni romain, ni empire. This agglomeration which called itself and still calls itself the Holy Roman Empire was in no way holy, nor Roman, nor an empire.”
—Voltaire [François Marie Arouet] (1694–1778)
