This large-scale collective and interdisciplinary project aims to produce a new research tool: a multi-volume dictionary providing a comprehensive article (around 500 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 is based on original research of the highest scientific level.The dictionary will be published in English. The first volume contains over 160 articles on words with the letters Alpha to Gamma.
