In 1724, Sylvester, a native of the island of Cyprus, was elected Patriarch of the Greek Orthodox Church of Antioch and All the East. For more than four decades, he endeavored to preserve the legacy of one of the earliest Christian Churches in the Levant. He faced major challenges because of the ever changing balance of power between the Latin Church and its missionaries, the Patriarchate of Constantinople, the French and English interests in the Levant, and the central and local Ottoman authorities. In his efforts to provide church books for the Arab Orthodox Christians, Sylvester was helped by rulers of the Romanian Principalities, Moldavia and Wallachia. He printed a number of books in Jassy and Bucharest and opened an Arabic press in Beirut. Alongside his patriarchal duties, Sylvester was also an accomplished icon painter. His works, in the Post-Byzantine Greek style of the 18th century, are preserved in Syrian and Lebanese churches, as well as elsewhere. Their study reveals just another aspect of his complex activity. The book presents for the first time in English the biography and achievements of Sylvester of Antioch, based on a wide range of contemporary Greek, Arabic and Romanian historical sources.
