Of the tyranny of Eugenius and the victory won through faithby the Emperor Theodosius
In this manner the peace of the churches was secured by the most religious emperor. Before the establishment of peace he had heard of the death of Valentinianus and of the usurpation of Eugenius and had marched for Europe.
At this time there lived in Egypt a man of the name of John, who had embraced the ascetic life. Being full of spiritual grace, he foretold many future events to persons who from time to time came to consult him. To him the Christ-loving emperor sent, in his anxiety to know whether he ought to make war against the tyrants. In the case of the former war he foretold a bloodless victory. In that of the second he predicted that the emperor would only win after a great slaughter. With this expectation the emperor set out, and, while drawing up his forces, shot down many of his opponents, but lost many of his barbarian allies.
When his generals represented that the forces on their side were few and recommended him to allow some pause in the campaign, so as to muster an army at the beginning of spring and out-number the enemy, Theodosius refused to listen to their advice. “For it is wrong,” said he, “to charge the Cross of Salvation with such infirmity, for it is the cross which leads our troops, and attribute such power to the image of Hercules which is at the head of the forces of our foe.” Thus in right faith he spoke, though the men left him were few in number and much discouraged. Then when he had found a little oratory, on the top of the hill where his camp was pitched, he spent the whole night in prayer to the God of all.
About cock-crow sleep overcame him, and as he lay upon the ground he thought he saw two men in white raiment riding upon white horses, who bade him be of good cheer, drive away his fear, and at dawn arm and marshal his men for battle. “For,” said they, “we have been sent to fight for you,” and one said, “I am John the evangelist,” and the other, “I am Philip the apostle.”
After he had seen this vision the emperor ceased not his supplication, but pursued it with still greater eagerness. The vision was also seen by a soldier in the ranks who reported it to his centurion. The centurion brought him to the tribune, and the tribune to the general. The general supposed that he was relating something new, and reported the story to the emperor. Then said Theodosius, “Not for my sake has this vision been seen by this man, for I have put my trust in them that promised me the victory. But that none may have supposed me to have invented this vision, because of my eagerness for the battle, the protector of my empire has given the information to this man too, that he may bear witness to the truth of what I say when I tell you that first to me did our Lord vouchsafe this vision. Let us then fling aside our fear. Let us follow our front rank and our generals. Let none weigh the chance of victory by the number of the men engaged, but let every man bethink him of the power of the leaders.”
He spoke in similar terms to his men, and after thus inspiring all his host with high hope, led them down from the crest of the hill. The tyrant saw the army coming to attack him from a distance, and then armed his forces and drew them up for battle. He himself remained on some elevated ground, and said that the emperor was desirous of death, and was coming into battle because he wished to be released from this present life: so he ordered his generals to bring him alive and in chains. When the forces were drawn up in battle array those of the enemy appeared by far the more numerous, and the tale of the emperor's troops might be easily told. But when both sides had begun to discharge their weapons the front rank proved their promises true. A violent wind blew right in the faces of the foe, and diverted their arrows and javelins and spears, so that no missile was of any use to them, and neither trooper nor archer nor spearman was able to inflict any damage upon the emperor's army. Vast clouds of dust, too, were carried into their faces, compelling them to shut their eyes and protect them from attack. The imperial forces on the other hand did not receive the slightest injury from the storm, and vigorously attacked and slew the foe. The vanquished then recognised the divine help given to their conquerors, flung away their arms, and begged the emperor for quarter. Theodosius then yielded to their entreaty and had compassion on them, and ordered them to bring the tyrant immediately before him. Eugenius was ignorant of how the day had gone, and when he saw his men running up the hillock where he sat, all out of breath, and showing their eagerness by their panting, he took them for messengers of victory, and asked if they had brought Theodosius in chains, as he had ordered. “No,” said they, “we are not bringing him to you, but we have come to carry you off to him, for so the great Ruler has ordained.” Even as they spoke they lifted him from his chariot, put chains upon him, and carried him off thus fettered, and led away the vain boaster of a short hour ago, now a prisoner of war.
The emperor reminded him of the wrongs he had done Valentinianus, of his usurped authority, and of the wars which he had waged against the rightful emperor. He ridiculed also the figure of Hercules and the foolish confidence it had inspired and at last pronounced the sentence of right and lawful punishment.
Such was Theodosius in peace and in war, ever asking and never refused the help of God.
