In accordance with the same principles he ordered a complete destruction of the remains of the idolatrous shrines, that our posterity might be saved from the sight of even a trace of the ancient error, this being the motive which he expressed in the edict published on the subject. Of this good seed sown he is ever reaping the fruits, for he has the Lord of all on his side. So when Rhoïlas, Prince of the Scythian Nomads, had crossed the Danube with a vast host and was ravaging and plundering Thrace, and was threatening to besiege the imperial city, and summarily seize it and deliver it to destruction, God smote him from on high with thunderbolt and storm, burning up the invader and destroying all his host. A similar providence was shewn, too, in the Persian war. The Persians received information that the Romans were occupied elsewhere, and so in violation of the treaty of Peace, marched against their neighbours, who found none to aid them under the attack, because, in reliance on the Peace, the emperor had despatched his generals and his men to other wars. Then the further march of the Persians was stayed by a very violent storm of rain and hail; their horses refused to advance; in twenty days they had not succeeded in advancing as many furlongs. Meanwhile the generals returned and mustered their troops.
