The bright oriental sun streamed down upon it, and as the trumpets sounded from beneath the imperial balcony, there filed into the arena the glittering troops of the empire, gorgeous in color and appointments, with lofty crests and gleaming armor, with shimmering spear-tips, prancing horses, towering elephants, and mighty engines of war and siege, with archers and spearmen, with sounding trumpets and swaying standards and, high over all, the purple Labarum, woven in gold and jewels,-the sacred banner of Constantine.

They will desert from the Labarum, which Constantine carried to victory, to our standards; and those standards are all there, ready for use; they have been made in this city and are lying hidden in the house of Apollodorus.

Marcus Aurelius died in 180 A.D. Substantially a century later, in 312, Constantine won the battle of the Milvian Bridge with his troops fighting under the Labarum, a standard bearing a cross with the device "In hoc signo vinces"; By this sign conquer.
