This volume strives to uncover the sources utilized by Jacob of Edessa in his Syriac revision of the biblical books of Samuel around 705CE. Noting that a colophon states that these sources derived from both the Syrians and the Greeks, the first part of the book deals with the relationship of the Peshitta, the Syro-Hexapla and Greek (Septuagint) texts in Jacob’s manuscript. This leads naturally into the heart of the volume which is a careful examination of the relative presence of the major Greek textual families within the manuscript. A final section treats the extent and nature of readings outside the major Syriac and Greek traditions. The findings should be of particular interest to scholars in Old Testament textual criticism and Syriac literature.
