I published this review in the mid-1970s, shortly after completing my own doctoral dissertation:--
Septuagint students would probably all account the published works of the late P. Walters (né Katz) as worth their weight in gold. His was a combination of linguistic horse-sense and text-critical flair which is rare if not unique in the field. In language he might have become either a Hebraist or a Hellenist of distinction, but chose to direct his intelligence towards the neglected discipline of Septuagint studies and especially to the question of the basic text. His classic monograph Philo's Bible (Cambridge, 1950), in which by a piece of acute observation he dealt a disabling blow to Kahle's view of Septuagint origins, established his reputation beyond dispute. In the light of this, the posthumous publication of his Cambridge thesis, with many improvements and additions incorporated, is a joy; and his pupil Dr. Gooding is to be congratulated on the completion of what judging by the Editor's Preface cannot have been a straightforward task.
Walters has here done for Thackeray's Grammar what Jellicoe did for Swete. Under the main heads of Grammatical Corruptions (Part I) and Semitisms (Part II) the book takes the form of a selective grammar, and hence goes a long way towards meeting a desperate need, for in practice Thackeray never took us much beyond orthography, while Walters is rich in syntactical and semantic insights. In a longer and more technical review (JTS N.S. Vol. XXV, Part I, p. 148ff.) S. P. Brock describes the book as "not something for the tiro," but anyone engaged in first-line Septuagint study will find it an indispensable work of reference. It is equipped with excellent indices, to Greek, Hebrew and Latin words, to Biblical passages, to ancient texts and to papyri. Part I contains much to interest the specialist in Hellenistic and New Testament Greek, and the whole, but particularly Part II, is full of useful examples in Old Testament textual criticism, even if the treatment does not claim to exhaust a comprehensive list of problems. In the light of new knowledge one may sometimes be bound to differ from Walters on points of detail, but his method, elegant, economical and convincing, essentially stands, and is perhaps shown at its best in the Excursuses. Incidentally Wutz's transcription theory is given short shrift on grounds of method.
Small criticisms are that the subtitle is a little misleading, for the book is in fact weighted towards corruptions: emendations Dr. Walters intended to take up more fully in a second volume which he did not write; and the language has in places been insufficiently purged of its Teutonic tinge, though never to the point of real obscurity. Perhaps this latter feature may offend American readers less than British.
