Hist. Notes: A remarkable scene, apparently portraying not only the conquest of the Empire over its Eastern enemies -- typical of the FEL TEMP REPARATIO series as well as the previous century and a half of Roman Imperial coinage -- but also the triumph of the newly-favored Christian religion over non-Roman, non-Christian Pagans. Constantine was famously the first Christian Roman Emperor, but the popularity and political supremacy of the new religion were not yet achieved. In the long history of European Imperial propaganda using Christianity to justify attacking foreigners and political enemies, this coin is surely among the first.
