This program unit focused on Late Antiquity in the East aims to provide a home for the study of religious traditions that are rooted in Mesopotamia, Persia, and western Asia, particularly those parts that were outside the Roman cultural reach such as Zoroastrianism, Manichaeism, and Mandaeism. While the unit will focus on late antiquity, many of these traditions, and particularly their extant texts come to us from much later periods, and this scholarly issue will be part of our discussions. In addition, many of the traditions that were born in this time and place also spread to other parts of the world, and the study of them in those forms and contexts also has a place within this program unit, as does investigation of their response to the rise of Islam in the region. In addition, this unit’s focus is not exclusively on those traditions that developed uniquely in this region, but also those which, when transplanted there, had significant evolutions in that milieu that differ from their counterparts in other times and places (e.g. Christianity, Judaism). We likewise encourage research which focuses on the interaction between the various communities and traditions of this place and time.
