This panel aims to showcase some of the recent investigations into the Septuagint vocabulary that are conducted according to the methodology of the Historical and Theological Lexicon of the Septuagint (HTLS). HTLS is a collective and interdisciplinary project, a multi-volume dictionary on the most significant terms or vocabulary groups found in the Septuagint Bible. Each term is analyzed within six sections: Archaic, Classical and Hellenistic Greek; papyri and inscriptions; the Septuagint and its Hebrew equivalents; Jewish literature in Greek; the New Testament; and early Christian literature. The aim is to investigate meanings, usages, and possible semantic evolutions of these significant words. Therefore, HTLS is a useful tool for the in-depth study of the Septuagint from both philological, historical, and exegetical perspectives. HTLS plans to release four volumes and their electronic version for the Mohr Siebeck publishing house in Tübingen. The first volume, which includes over 150 articles on terms beginning with the letters from alpha to gamma, was made available in 2020. The second volume, which includes the letters delta to iota, is in preparation.Chair: Samuele Adorno (FSCIRE) Speakers:Antonella Bellantuono (Université Catholique de Lille), Judaism and the Irrational: An Anthropological and Linguistic Analysis of θυμόςBeatrice Bonanno (Université Catholique de Louvain), The Use of ἱκανός in Reference to God and to People in the SeptuagintEberhard Bons (Université de Strasbourg), How to Speak of Human Life?
