This brilliant book Paul Veyne is not a narrative of facts, but a historical analysis. This is a test, not a timeline. This accuracy is noteworthy especially with regard to comments from people disappointed by the contents of the book, given the way that leaves perhaps assume otherwise. That said, the quality of the book lies precisely in this synthesis that Paul Veyne is able to develop. It is mainly concerned with the conversion of Constantine, and his conclusions often go against the common doxa. All this is reasoned and supported very convincingly. Note the last chapter exciting, seemingly unrelated to the rest, on the links between montotheisme and polytheism in the Old Testament. Probably not the best of his works, this title nevertheless reveals insight and erudition of its author.
