This comprehensive yet user-friendly primer to the Septuagint (LXX) acquaints readers with the Greek versions of the Old Testament. It is accessible to students, assuming no prior knowledge about the Septuagint, yet is also informative for seasoned scholars. The authors, both prominent Septuagint scholars, explore the history of the LXX, the various versions of it available, and its importance for biblical studies. This new edition has been substantially revised, expanded, and updated to reflect major advances in Septuagint studies. Appendixes offer helpful reference resources for further study.
