This volume contains the proceedings of the 4thTYPARABIC Conference, held in Venice between May 27-29, 2025, together with a selection of additional studies on the religious and intellectual history of Arabic-speaking communities in the Ottoman Levant, resulting from earlier team's conferences. It documents a significant moment of scholarly exchange, while offering a varied contribution to the study of Arabic print culture and Church history. The conference papers concentrate on the Italian connection in the development of Arabic printing in 18th-century Europe and the Near East. They analyze the technical, commercial, and ecclesiastical networks that linked Italian printing centers - above all Venice - with Levantine and Eastern European presses, emphasizing the circulation of type, texts, and craftsmen. The additional contributions expand the thematic scope of the volume by addressing theological debates and cultural interactions within Arabic-speaking Christianity. Through focused case studies, they place Eastern Christians within the wider Ottoman and Mediterranean contexts, highlighting patterns of exchange, adaptation, and intellectual continuity. Taken together, the essays provide a coherent and methodologically rigorous account of the dialogue between print, theology, and cross-cultural connections in the 18th-century Ottoman Levant.
