If the empire had been afflicted by any recent calamity, by a plague, a famine, or an unsuccessful war; if the Tiber had, or if the Nile had not, risen beyond its banks; if the earth had shaken, or if the temperate order of the seasons had been interrupted, the superstitious Pagans were convinced that the crimes and the impiety of the Christians, who were spared by the excessive lenity of the government, had at length provoked the divine justice.
Edward Gibbon, The Decline and Fall of the Roman Empire
