The encounter of imperial Rome with the nascent Christian religion produced the tradition upon which our culture is based. So legion are the examples of their mutual interaction that the source of certain facets of imperial Christian thought, art, and culture is not always clear. In seeking traces of Christian impact on the empire in the Age of Constantine, it was natural for scholars to look to the coinage, the largest surviving body of imperial art and propaganda, and find such traces they did. More recent thought, however, has re-analyzed most of these alleged examples of Christian symbolism and has correctly found them to be either personal symbols of the emperor or merely minor adjuncts supplied by lesser mint-officials who, in their selection of mint and/or sequence marks, most probably in no way reflected imperial policy or belief.
