This book is an English translation of Decret's 1996 Le Christianisme en Afrique du nord ancienne. It provides a general survey of north African Christianity from its emergence at the end of the second century until the Arab incursion in the second half of the seventh century. It provides an overview for those who have no familiarity with the story of Christians in what is today Algeria, Tunisia and Libya. The reader is introduced to Perpetua, Tertullian, Cyprian, the Donatists and Augustine. Most of the major topics one expects to find covered are treated. There are several chapters on Cyprian, but the most detail comes with the discussion of Donatism. What is particularly pleasing is a chapter on religious diversity where there is some discussion about pagans, Jews and Manichees (Decret's own area of specialisation). While helpful for the novice student, there is nothing to be found in this book for the specialist or more advanced student. The style is narrative and descriptive rather than analytical and critical. Thus Jerome's comment about Tertullian's father being a centurion is repeated but not subject to the scrutiny to which Timothy Barnes, for example, subjected it. The identification of the bishop in De pudicitia with the bishop of Rome is made without the slightest reference to the debate on this point. Decret states that some confessors at the time of the Decian persecution were issuing certificates of readmission to the Church for those who had lapsed. A closer reading of Cyprian's letters reveals that in fact they still accepted that Cyprian would be the one to readmit them but they could choose who was to be readmitted. To speak of an appeal for the reintroduction of the Theodosian Code (instead of the reintroduction of Theodosius i's law of 380) in 404 is quite inaccurate and misleading. There are minimal footnotes, most of which are to ancient sources since the author does not much engage with modern scholarship explicitly, although it – particularly French scholarship – has informed his writing. In summary, this is a solid enough volume of value to someone meeting ancient north African Christianity for the first time.
