The claim at the heart of this book has been carefully researched by several generations of scholars and is orthodox in academic circles, if not beyond. Christians under the Roman Empire were neither constantly persecuted nor martyred in huge numbers for their faith. They were prosecuted from time to time for alleged sedition, holding illegal meetings or refusing to sacrifice to the emperor. They were, like other convicts, sometimes tortured and executed in horrible ways. They seem to have been regarded by many Romans with distaste as a particularly silly superstition. But Christian stories of thousands of individual and mass martyrdoms over centuries have at best a limited basis in historical fact, and in many cases are sheer fiction.
