Thomas Römer's research focuses on the birth of the Bible in the context of the ancient world. From a history of religion perspective, his approach is characterized by a philological and literary analysis of the texts, in dialogue with the history and archaeology of the ancient Near East. This approach highlights the function of texts in their original environments, responding to issues of identity, culture, society and politics. This has enabled him to propose new historical syntheses, notably on the formation of the Pentateuch and biblical historiography, or on the origins of gods and their cults in the ancient kingdoms of Israel and Judah.
