Two inscriptions with images of fish carved on them from the Catacomb of Saint Sebastian in Rome may well date to c. 150 C.E., but their date and their Christian identity are not as certain as those of the Avercius inscription. The vast majority of attempts by historians, archaeologists, art historians and epigraphers to find archaeological evidence of Christianity from 40 to 165 C.E. have foundered for lack of critical evidence, though not for want of desire or effort.
