In the late sixteenth century, a German Lutheran scholar named Martin Crusius compiled an exceptionally rich record of Greek life under Ottoman rule. Although he never left his home in the university town of Tübingen, Crusius spent decades annotating books and manuscripts, corresponding with the Greek Orthodox Patriarch, and interviewing Greek Orthodox alms-seekers. Ultimately, he gathered his research into a seminal work called the Turcograecia, which served for centuries as Europe’s foremost source on Ottoman Greece. Yet as Richard Calis reveals, Crusius’s massive—and largely untapped—archive has much more to tell us about how early modern Europeans negotiated cultural and religious difference. In particular, Crusius’s work illuminates Western European views of the religious “other” within Christianity: the Greek Orthodox Christians living under Ottoman rule, a group both familiar and foreign. Many Western Europeans, including Crusius, developed narratives of Greek cultural and religious decline under Ottoman rule. Crusius’s records, however, reveal in exceptional detail how such stories developed. His interactions with his Greek Orthodox visitors, and with a vast network of correspondents, show that Greeks’ own narratives of hardship entwined in complex ways with Western Europeans’ orientalist views of the Ottoman world. They also reflect the religious tensions that undergirded these exchanges, fueled by Crusius’s fervent desire to spread Lutheran belief across Ottoman Greece and the wider world. A lively intellectual history drawn from a forgotten archive, The Discovery of Ottoman Greece (Harvard UP, 2025) is also a perceptive character study, in which Crusius takes his place in the history of ethnography, Lutheran reform, and European philhellenism.
