The study of cultural interaction as documented in the textual output of Egypt, Greece, and Rome is in flux. Egyptologists, who traditionally had paid less attention to texts written under Ptolemaic and especially Roman rule than to earlier material, have been devoting more of their energies to the arduous duty of editing Demotic papyri. Many such documents provide evidence of Greek-Egyptian cross-pollination, even if the exact nature of that exchange is hard to puzzle out. As the editor of one of those texts acknowledges here without despair: “Any conclusion may be overturned tomorrow” (p. 347). Classicists, on their part, have been producing less Hellenocentric readings of textual documents written in Hellenistic and Roman Egypt, and also increasingly sophisticated literary and historical analyses that are informed by theoretical trends outside of classics. Many of the contributors to this volume are directly responsible for rocking the Greco-Egyptian textual boat. In fact, beginning nearly two decades ago, the editor himself has been offering challenging studies of Greco-Egyptian literary and cultural interaction. This book is of immediate and obvious importance to those working on Greek and Roman Egypt. As I explain below, however, it may also be of interest to those studying cross-cultural contact in the ancient world more generally.
