This volume honours the life and scholarship of James K. Aitken (1968-2023), a distinguished scholar of Hebrew and Early Jewish Studies at the University of Cambridge. Bringing together fourteen original essays by colleagues, students, and friends, the collection explores themes central to Aitken's work. Contributors examine the interplay between language and identity in ancient Jewish communities, with particular attention to the Septuagint and its place within the history of Greek.Aitken's intellectual legacy is reflected in the breadth of topics covered, from lexical studies and syntactic analysis to sociolinguistic phenomena and historical context. The essays build on his pioneering research and continue conversations he began, offering fresh insights into the lived realities of Jews in the Hellenistic world.More than a scholarly tribute, this volume is a testament to Aitken's collegial spirit and mentorship. The editors-William A. Ross, Marieke Dhont, and Christopher Fresch-were all shaped by his guidance and friendship, and have curated a collection that reflects both his academic influence and personal impact. With contributions from leading international scholars, this book stands as a fitting memorial to a beloved teacher, collaborator, and friend.
