After such a vision, it is useless to relate any others: they are all a species either of knavery or folly. Visions of the first kind are under the province of justice; those of the second are either visions of diseased fools, or of fools in good health. The first belong to medicine, the second to Bedlam.
VISION OF CONSTANTINE.
Grave theologians have not failed to allege a specious reason to maintain the truth of the appearance of the cross in heaven; but we are going to show that these arguments are not sufficiently convincing to exclude doubt; the evidences which they quote being neither persuasive nor according with one another.
First, they produce no witnesses but Christians, the deposition of whom may be suspected in the treatment of a fact which tended to prove the divinity of their religion. How is it that no Pagan author has made mention of this miracle, which was seen equally by all the army of Constantine? That Zosimus, who seems to have endeavored to diminish the glory of Constantine, has said nothing of it, is not surprising; but the silence appears very strange in the author of the panegyric of Constantine, pronounced in his presence at Trier; in which oration the panegyrist expresses himself in magnificent terms on all the war against Maxentius, whom this emperor had conquered.
Another orator, who, in his panegyric, treats so eloquently of the war against Maxentius, of the clemency which Constantine showed after the victory, and of the deliverance of Rome, says not a word on this apparition; while he assures us, that celestial armies were seen by all the Gauls, which armies, it was pretended, were sent to aid Constantine.
This surprising vision has not only been unknown to Pagan authors, but to three Christian writers, who had the finest occasion to speak of them. Optatianus Porphyrius mentions more than once the monogram of Christ, which he calls the celestial sign, in the panegyric of Constantine which he wrote in Latin verse, but not a word on the appearance of the cross in the sky.
Lactantius says nothing of it in his treatise on the "Death of Persecutors," which he composed towards the year 314, two years after the vision of which we speak; yet he must have been perfectly informed of all that regards Constantine, having been tutor to Crispus, the son of this prince. He merely relates, that Constantine was commanded, in a dream, to put the divine image of the cross on the bucklers of his soldiers, and to give up war: but in relating a dream, the truth of which had no other support than the evidence of the emperor, he passes, in silence over a prodigy to which all the army were witnesses.
Further, Eusebius of Cæsarea himself, who has given the example to all other Christian historians on the subject, speaks not of this wonder, in the whole course of his "Ecclesiastical History," though he enlarges much on the exploits of Constantine against Maxentius. It is only in his life of this emperor that he expresses himself in these terms: "Constantine resolved to adore the god of Constantius; his father implored the protection of this god against Maxentius. Whilst he was praying, he had a wonderful vision, which would appear incredible, if related by another; but since the victorious emperor has himself related it to us, who wrote this history; and that, after having been long known to this prince, and enjoying a share in his good graces, the emperor confirming what he said by oath—who could doubt it? particularly since the event has confirmed the truth of it.
"He affirmed, that in the afternoon, when the sun set, he saw a luminous cross above it, with this inscription in Greek—'By this sign, conquer:' that this appearance astonished him extremely, as well as all the soldiers who followed him, who were witnesses of the miracle; that while his mind was fully occupied with this vision, and he sought to penetrate the sense of it, the night being come, Jesus Christ appeared to him during his sleep, with the same sign which He had shown to him in the air in the day-time, and commanded him to make a standard of the same form, and to bear it in his battles, to secure him from danger. Constantine, rising at break of day, related to his friends the vision which he had beheld; and, sending for goldsmiths and lapidaries, he sat in the midst of them, explained to them the figure of the sign which he had seen, and commanded them to make a similar one of gold and jewels; and we remember having sometimes seen it."
