Book excerpt: It was long believed that Roman Jews lived in complete isolation. This book offers a refutation of this thesis. It focuses on the Jewish community in third and fourth-century Rome, and in particular on how this community related to the larger, non-Jewish world that surrounded it. Jewish archaeological remains and Jewish funerary inscriptions from Rome are examined from various angles, and compared to pagan and early Christian material and epigraphical remains. The author has shown great comprehensiveness, thoroughness, and accuracy in examining this epigraphic evidence. He also discusses the enigmatic legal treatise called the Collatio. This volume proposes a new way in which the relationship between Jews and non-Jews in late antiquity can be studied. As such, it is an important and useful addition to the literature on Roman Jewry in the middle Empire.
