Marsh’s Library in Dublin, Ireland, is an immaculately preserved library from the early eighteenth century. Founded by Archbishop Narcissus Marsh, the library has an extensive collection of Jewish and Hebrew books which includes Hebrew Bibles, Talmudic texts, rabbinic writings, and Yiddish books that date back to the early modern period. This study explores a cross section of the Jewish and Hebrew books in Marsh’s collection, with particular focus on issues of materiality—that is, how these books as material artefacts can inform our understanding of early modern history, religion, and intercultural engagement. We suggest that these books, a majority of which come from Marsh’s personal collection, are a valuable resource for reflection on (1) Christian engagement with Jewish culture in the seventeenth and eighteenth centuries, (2) the production, use, and travel of Jewish books in early modern Europe, and (3) snapshots of Jewish life in early modern Ireland and beyond.
