Why did christian art become publicly accepted during the third century?

The beginnings of an identifiable Christian art can be traced to the end of the second century and the beginning of the third century. Considering the Old Testament prohibitions against graven images, it is important to consider why Christian art developed in the first place. The use of images will be a continuing issue in the history of Christianity. The best explanation for the emergence of Christian art in the early church is due to the important role images played in Greco-Roman culture.
