The International Organization for Septuagint and Cognate Studies


The International Organization for Septuagint and Cognate Studies (IOSCS) is a nonprofit, learned society formed to promote international research in and study of the Septuagint and related texts. By the term Septuagint is meant the ancient translations of the Hebrew Scriptures into Greek, including both the translation of the Pentateuch and that of the other books of the “Alexandrian Canon.” By the term cognate studies is meant the study of the ancient translations made from the Septuagint (“daughter versions”) and the so-called apocryphal and pseudepigraphical literature circulating around the turn of the era.


Individuals and institutions with an interest in the Septuagint and related materials are welcome as members in the IOSCS. For more information about membership, please follow this link.

New IOSCS Presidency

Following a distinguished six years of service to the IOSCS, at the end of this year Prof. Rob Hiebert is stepping down as President. His contribution to LXX studies has been significant, not least through his involvement in the New English Translation of the Septuagint, the SBL Commentary on the Septuagint Series, and his leadership of the John Wevers Institute at Trinity Western University. He is also preparing the forthcoming volume on 4 Maccabees for the Göttingen Septuaginta series. We are grateful for his leadership over his two presidential terms.

Prof. Hiebert’s successor in the role, Prof. Alison Salvesen, studied with James Barr and Sebastian Brock at Oxford and wrote her DPhil on Symmachus in the Pentateuch (1988). She was the main editor of the Oxford Handbook of the Septuagint (2021) and is one of the founding members of the Hexapla Project. Among her many interests, she regularly writes on the later Jewish Greek versions and their reception history. She looks forward to serving the IOSCS community in this capacity.

A statement from the IOSCS Executive Committee concerning Robert A. Kraft

We report the sad news that Robert A. Kraft, a founding member and longtime participant in the IOSCS, died on September 15, 2023 at the age of 89. Bob was a scholar with interests that encompassed the entirety of ancient Jewish and Christian literature. He was a member of the first Executive Committee of the IOSCS (see BIOSCS 2) and served the organization in a range of capacities since its inception. He presented the paper “Translation Technique and Jewish Greek Idiom: Some Examples and Prospects” at the 1968 organizational meeting of the IOSCS. In addition to his publications on the Septuagint, he edited the first two volumes in the SCS series, Septuagintal Lexicography (SCS 1; Missoula, MT: Scholars Press, 1972), which laid the groundwork for a lexicon of the Septuagint and the CATSS project, and 1972 Proceedings of the International Organization for Septuagint and Cognate Studies and the Society of Biblical Literature Pseudepigrapha Seminar (SCS 2: Missoula, MT: Scholars Press, 1972). He was a pioneer in and evangelist for the use of computer technology in textual study, particularly with respect to the Septuagint. He co-directed with Emanuel Tov the Computer Assisted Tools for Septuagint Studies (CATSS) project, which produced the first parallel aligned text of the Septuagint with morphological analysis. Among his publications on the Septuagint, which included a collaboration with Tov on the DJD publication of the Naḥal Ḥever Minor Prophets Scroll, he edited with Tov and contributed to Computer Assisted Tools for Septuagint Studies Volume 1: Ruth (SCS 20; Atlanta: Scholars Press, 1986), which introduced the results of the CATSS project to the scholarly public, and he edited the PHI CCAT/CATSS Demonstration CD ROM #1, which contained the CATSS databases and showed the benefits of electronic storage and distribution of textual data. Throughout his career, Bob pushed the boundaries of what might be possible in the scholarly study of ancient texts, and the IOSCS and the scholarly academy more broadly are in his debt. In addition to his scholarly work, he would often grace friends and colleagues with a poem for important occasions, and he could always be counted on to try to fix something that others thought irredeemably broken. He will be greatly missed by all who knew him.

A statement from the IOSCS executive to all members concerning James 'Jim' Aitken

It is with great sadness that we announce the passing of Dr. James Aitken, Professor of Hebrew and Early Jewish Studies at the University of Cambridge. Members of the IOSCS also knew him as an active scholar within the discipline of Septuagint Studies, a member of the executive committee, and a regular participant at IOSCS conferences. Among his many important publications are No Stone Unturned: Greek Inscriptions and Septuagint Vocabulary (Eisenbrauns, 2014) and, as editor, The T&T Clark Companion to the Septuagint (2015). He also delivered the 2021–22 Grinfield Lectures at the University of Oxford on the topics, “The Septuagint and Scribal Creativity in Egypt,” “The Septuagint—A Translation Among Translations,” and “The Septuagint, Editing, and Textual Production in Ancient Judaism.” These contributions to scholarship were indicative of his keen interest in the language, exegesis, and place within Second Temple Jewish society of the Greek version of the Jewish Scriptures. But more than an outstanding scholar, Jim was also a good friend to many, someone who gave generously of his time and his wisdom to both colleagues and students alike. He will be sorely missed.
