In 2024, 300 years are commemorated since the Arabic-speaking Christians of Ottoman Syria split into the Greek Orthodox Church of Antioch and the Greek Catholic Melkite Church. In 1724, printing was a potent weapon in the hands of the Arab Christians’ leaders, intent on making their dogmas – and opinions of each other – known to a broader audience. It all started in one of the Romanian Principalities, Wallachia (now in Romania), in 1701-1702, when Athanasios Dabbas, at the time Antiochian Metropolitan of Aleppo, printed two Arabic liturgical texts that he distributed freely to the parishes of Greater Syria, where no presses existed. This achievement was enabled by the help he received from the prince Constantin Brâncoveanu (1698-1714) and his master printer Antim the Iberian, a future Metropolitan of Wallachia (d. 1716). Dabbas then transferred the typographic tools and printing know-how from Bucharest to Aleppo in Syria, where he established the first Arabic press in the Ottoman lands and printed 11 titles by 1711. His successor on the Antiochian See, Sylvester (1724-1766), resumed printing in the Romanian Principalities of Moldavia and Wallachia, where Syrian monks manufactured Arabic type that they used in printing four books in Iași (1745-1746), two in Bucharest (1747), and then five in Sylvester’s new press in Beirut, the first Christian Orthodox press of Lebanon (1750-1753). In this paper, I shall tell the story of these outstanding characters and their Arabic books, products of a visionary plan where importing the printing technology was included to bring modernity to the Ottoman-ruled Middle East, and unity to the troubled Church of Antioch. I am conducting this novel research within the ERC-funded TYPARABIC project I am heading in Bucharest, Romania (2021-2026).
