This incomplete, early twentieth-century edition was one of the first modern attempts to bring textual criticism to bear on the Septuagint, the Greek version of the Hebrew scriptures which originated in the third century BCE. It is still widely consulted today. Originally issued in nine parts between 1906 and 1940, this reissue is bound in four volumes. This, the final volume, contains the books of Esther, Judith, and Tobit. Following Swete's smaller Septuagint (1887–1894) the running text is that of Codex Vaticanus (B) supplemented by Codex Alexandrinus (A) or N when B is defective. The edition includes an extensive critical apparatus, citing key uncial manuscripts and fragments, twenty-seven cursive manuscripts, many freshly collated for the edition, the Sahidic, Ethiopic, Syriac and Old Latin versions, and quotations from Latin writers including Cyprian and Augustine. It remains an invaluable resource for the study of the Septuagint.
