"Just hundred years after the first edition of Albrecht Dietrich's Eine Mithrasliturgie (Leipzig 1903; 1923), the present book offers a complete new edition of so complex a text. It provides the Greek text, an English translation, a punctual introduction, an extensive commentary, an index of Greek words and of the various voces magicae, and, finally, also an appendix, with photographic reproductions of the papyrus. ... Not only Hans Dieter Betz is one of the most gifted scholars in the domain of primeval Christianity and Hellenistic religions, but he already devoted to the Mithras Liturgy a monographic essay, which is here enriched and largely supplemented. We particularly appreciated how Betz deals with the critical debate which spread from Dietrich's book (in particular the criticism put forward by one of the most important scholars of Mithraism, the Belgian Franz Cumont) and how he sets Dietrich in the historical and cultural milieu of his age."
