The symbol {image "monogram4.gif"} frequently occurs upon the coins of Valeus (A.C. 364-378). And upon one coin of this Emperor we see the letter P surmounting a cross; surrounded by the legend _Gloria Romanorum_. Upon a coin of Valentinianus II. we see Victory holding a round object surmounted by a cross, the legend being _Victoria Augustorum_. On the coins of Theodosius I. (A.C. 378-395) we find representations of the Emperor holding a round object surmounted by a Phoenix, and of the Emperor holding a round object surmounted by a Victory; as also of Victory holding a round object surmounted by a cross. This Emperor Theodosius I., better known as Theodosius the Great, after securing sole control of the Roman Empire brought about the final disruption of the world-wide dominions of Rome by bequeathing them in two portions to his sons Arcadius and Honorius; the elder, Arcadius, becoming Emperor of Constantinople and the East, while the younger, Honorius, became Emperor of Rome and the West: A.C. 395. Less than a century later, _viz._, between the years A.C. 475 and 480, the Western Empire was finally extinguished by Odoacer; the Eastern Empire surviving it nearly a thousand years, lasting as the latter did from the partition in A.C. 395 to the capture of Constantinople by Mahomet II. in A.C. 1453. It was, as stated in a previous chapter, upon the coins of an Emperor of the East, _viz._, Theodosius II., that the first example occurs of a representation of an Emperor holding a round object surmounted by a cross; though, as has been noted, instances of Victory carrying an object so surmounted had previously occurred. And it need only be added that the symbols {image "monogram3.gif"} and {image "monogram4.gif"}, often the centre of a circle or surrounded by a circular wreath of bay or laurel, continually occur upon the coins of the Eastern Empire, the symbol {image "asterisk.gif"} frequently, and the undisguised solar wheel, {image "solarwheel1.gif"} upon the coins of Eudoxia, Theodosius II., Leo I., and others. The evidence of the coins of the Roman Empire given in this and the two preceding chapters, coupled with the too-often forgotten fact that the only form of cross which could possibly be a representation of the instrument of execution to which Jesus was affixed was the very last form of cross to be adopted as a Christian symbol, cannot, it will be seen, lead the unprejudiced enquirer to any other conclusion than that the cross became the symbol of Christendom because the advent of Constantine and his Gauls made it a prominent symbol of the Roman Empire. And that the symbol in question was not altogether unconnected with Sun-God worship, should be equally clear to the reader. CHAPTER XIII. THE MONOGRAM OF CHRIST.
