But that story, when sifted to the bottom, according to the common version of it, will be found to be based on a delusion--a delusion, however, into which so good a man as Milner has allowed himself to fall. Milner's account is as follows: "Constantine, marching from France into Italy against Maxentius, in an expedition which was likely either to exalt or to ruin him, was oppressed with anxiety. Some god he thought needful to protect him; the God of the Christians he was most inclined to respect, but he wanted some satisfactory proof of His real existence and power, and he neither understood the means of acquiring this, nor could he be content with the atheistic indifference in which so many generals and heroes since his time have acquiesced. He prayed, he implored with such vehemence and importunity, and God left him not unanswered. While he was marching with his forces in the afternoon, the trophy of the cross appeared very luminous in the heavens, brighter than the sun, with this inscription, 'Conquer by this.' He and his soldiers were astonished at the sight; but he continued pondering on the event till night. And Christ appeared to him when asleep with the same sign of the cross, and directed him to make use of the symbol as his military ensign." Such is the statement of Milner. Now, in regard to the "trophy of the cross," a few words will suffice to show that it is utterly unfounded. I do not think it necessary to dispute the fact of some miraculous sign having been given. There may, or there may not, have been on this occasion a "dignus vindice nodus," a crisis worthy of a Divine interposition. Whether, however, there was anything out of the ordinary course, I do not inquire. But this I say, on the supposition that Constantine in this matter acted in good faith, and that there actually was a miraculous appearance in the heavens, that it as not the sign of the cross that was seen, but quite a different thing, the name of Christ. That this was the case, we have at once the testimony of Lactantius, who was the tutor of Constantine's son Crispus--the earliest author who gives any account of the matter, and the indisputable evidence of the standards of Constantine themselves, as handed down to us on medals struck at the time. The testimony of Lactantius is most decisive: "Constantine was warned in a dream to make the celestial sign of God upon his solders' shields, and so to join battle. He did as he was bid, and with the transverse letter X circumflecting the head of it, he marks Christ on their shields. Equipped with this sign, his army takes the sword." Now, the letter X was just the initial of the name of Christ, being equivalent in Greek to CH.
