The Classical World, Robin Lane Fox

The Classical World by Robin Lane Fox, esp chapters 48, 52, and 53 deals with and gives a brief background of Christianity and Roman Rule, and the roots of Christianity. It also shows an insight into what Pliny the Younger was like and his background, and by doing this it contrasts some Roman beliefs in comparison to some early Christian beliefs.
