This posthumous edition of Dr Walters’ The Text of the Septuagint provides a valuable working tool for specialists in Hellenistic and Classical Greek and the Old and New Testaments. The book is directed first to the practical task of producing a critical edition of the Septuagint, the Greek version of the Old Testament. Byzantine and Renaissance scholars both regarded the Greek Old Testament as belonging to the Church rather than to the heritage of classical literature which formed the proper object of their critical endeavours. It was therefore reproduced for centuries in much the same corrupt form and no complete critical edition was produced. The present work is a detailed study of the grammatical corruptions and semitisms in the LXX and is intended to stand as the prolegomenon to such an edition.
