Anna Angelini and Peter Altmann address pivotal issues on the biblical dietary prohibitions and their significance as practices and texts through philological, zooarchaeological, iconographic, and comparative ancient Near Eastern and Greco-Roman lenses. They explore theoretical frameworks adopted in modern interpretation, possible origins in relation to ancient Israelite religion and society, and location in relation to Priestly terminology and Deuteronomic tradition. The authors expand the arc of investigation to the Second Temple reception of the prohibitions in both the Dead Sea Scrolls and Greco-Roman discourses from the first centuries CE. With their foundational studies, they provide an approach to the dietary prohibitions, opening the way for reconstructing their path of development into their present-day contexts.
