This large-scale collective and interdisciplinary project aims to produce a new research tool: a multi-volume dictionary providing an article of between two and ten pages (around 600 articles in all) for each important word or word group of the Septuagint. Filling an important gap in the fields of ancient philology and religious studies, the dictionary will be based on original research of the highest scientific level.
This project has benefitted from funding from the Agence Nationale de la Recherche (French Research National Agency), the Maison Interuniversitaire des Sciences de l’Homme – Alsace (Strasbourg), the Melanchthon-Stiftung (Tübingen), and the Armin Schmitt Stiftung (Regensburg).
The first volume is projected to be published in 2018.
