The Testaments of the twelve patriarchs is a member of that intriguing body of ancient literature known as the Pseudepigrapha. Like many of its fellows it seems to have had Jewish roots that became Christian branches. One major question is at which point(s) in the work one can observe the transition, given the very complex history of both transmission and reception of this work. There are Hebrew and Aramaic fragments of related compositions, from both Qumran and the Cairo Geniza. However, the fullest forms of the Testaments are to be found in Christian manuscripts (Greek, Armenian, Slavonic, Ethiopic, etc.). The present volume marks what is probably the climax of Michael Stone's considerable contribution to research on the significant Armenian tradition of the Testaments, forty-five years after he first embarked on it. The first half of the book is the minor critical edition of the Armenian text , based on eleven medieval manuscripts out of the sixty-five extant ones evaluated. The second half supplies an English translation of the Armenian text, with notes discussing the Armenian translation in relation to the Greek tradition. The book provides both a serious overview of the complex manuscript tradition (and an index of variants) for the scholar, and a usable text and translation for the student. It also gives clear summaries of the results of Stone's research, namely that in spite of the late dates of the extant manuscripts, the translation style belongs to the period of Armenian renderings of the Greek biblical books (before the mid-fifth century), and that there was but a single translation of the Greek Testaments behind all the Armenian copies and the Epitome of the work.
