No subject in the history of the Roman Empire has more significance or more pitfalls than that of the local cultures of the provinces. The evidence is in each case, with the exception of Judaea and Egypt, relatively slight, disparate and ambiguous. But, on the one hand, the subject has very real attractions, which may lead to the building of vast but fragile historical theories, attempting to bring the distinctive culture of an area into a schematic relationship with events such as political movements or the spread of Christianity. On the other, we can never escape the possibility that the denial of the survival of a significant local culture may be falsified by new evidence; even worse, a local culture may have existed in a form which left no written records or datable artefacts.
Yet the problem must be faced, not only for the intrinsic interest which such cultures present, but for the light the enquiry sheds on Graeco-Roman civilization itself. We might conclude for one area that Graeco-Roman culture remained the merest façade, for another that it completely obliterated a native culture. More commonly, we will find a mixture or co-existence of cultures. In such a situation, again, the local element might have been culturally and socially insignificant, or, as it was in Egypt and in Judaea, embodied in a coherent traditional civilization with its own language, literature, customs, religion and (in Egypt) art-forms.
