The present volume makes accessible once more the groundbreaking work "The Septuagint Version of Isaiah" (1948) by Isac Leo Seeligmann (1907-1982), accompanied by two studies that have to be seen as prolegomena to the book. Seeligmann aims to understand the Septuagint as a witness of Hellenistic Judaism striving to maintain the text's special character as a document of faith. At the same time all of Seeligmann's works edited in this volume are documents of the suffering of European Judaism during the time of National Socialism.
