Since its publication in 1935, the Alfred Rahlfs edition of the Septuagint has served as the foundational text for Septuagint research around the world and an indispensable tool for theological and philological studies. Robert Hanhart’s improved and updated edition—which was published in 2006 and contains the complete text of the Greek Old Testament, a text-critical apparatus, and an introduction in German, English, Latin, and modern Greek—has set new standards for the academic study of the Greek Old Testament.
