Now the Gauls led by Constantine specially venerated the Solar Wheel. This had sometimes six and sometimes four spokes, {image "solarwheel1.gif"} or {image "solarwheel2.gif"}, and the warriors of their native land had long been in the habit of wearing a representation of the same upon their helmets. It is therefore not improbable that even before the date of the alleged vision when marching upon Rome, some such symbol formed the standard of Constantine's army. Anyhow, that the worthy Bishop Eusebius was, like other enthusiasts, liable to be at times carried by his enthusiasm beyond the limits of veracity, or else was the victim of imperial mendacity, is evident. For Eusebius tells us in the _Life of Constantine_ he wrote after the death of his patron, that the night after this miraculous "cross" and motto were seen in the sky above the Sun, the Christ appeared to Constantine, and, showing the Gaulish general the same sign that had been seen in the sky, directed him to have a similar symbol made, under which his army--an army, be it remembered, of Sun-God worshippers--should march conquering and to conquer![34] All that is really likely to have happened is that Constantine, wishing to encourage his troops, bade them rally round a standard on which was represented the sacred Solar Wheel venerated by the Gauls; and that as with this as a rallying point Constantine and his Gauls became masters of Rome, the symbol we are discussing became a Roman--and therefore, later on, upon the establishment of our faith as the State Religion of the Roman Empire, also a _Christian_--symbol. And a loop seems to have been sooner or later added to the top of the vertical spoke of the Gaulish symbol, so that Christians could accept it as a Monogram of Christ; as has already been hinted, and as will be demonstrated further on. A noteworthy point is that we have two accounts of Constantine's alleged vision of the Christ, and that they do not quite agree. The Bishop of Caesarea's account is, that the night after the Emperor--then only ruler of Gaul--and all his soldiers saw the "cross" and motto above the meridian sun, the Christ appeared to Constantine "With the same sign which he had seen in the heavens, and commanded him to make a likeness of that sign which he had seen in the heavens, and to use it as a safeguard in all engagements with his enemies."[35] But the author of _De Mortibus Persecutorem_, a work said to have been written during the reign of Constantine, and attributed to Lactantius, refers to the alleged vision as follows:-- "Constantine was admonished in his sleep to mark the celestial sign of God on the shields, and thus engage in battle. He did as he was commanded, and marked the name of the Christ on the shields by the letter X drawn across them with the top circumflexed. Armed with this sign his troops--"[36]
