Archeologists have compared bones from a Roman catacomb that was used for the burial of Christians to bones from other catacombs. The finding? The early Christians ate a lot of freshwater fish, whereas most Romans didn’t.
Comparing the catacomb results with those from other sites in Italy and in the western Mediterranean, the higher nitrogen and lower carbon figures indicate the consumption of freshwater fish. The contribution of such fish to the diet of the early Christians in Rome ranges from 18 to 43 per cent, averaging at around 30 per cent. . . .
“While distancing themselves from Jewish food taboos and generally avoiding meat derived from pagan sacrifices, the early Christians are normally hypothesised to have eaten the same food as their non-Christian Roman contemporaries,” the team says. “Within the larger context of what is currently known about Roman dietary habits, the inclusion of freshwater fish therefore comes as unexpected and raises questions about the social origins of Christianity as well.”
