After the Islamic conquest, the Greek Orthodox, so-called Melkite ( = Royalist), church fairly early adopted Arabic as its literary language. Their intellectual centres in Syria/Palestine were Jerusalem, along with the monaster ies of Mar Sabas and Mar Chariton in Judea, Edessa and Damascus. A great many Arabic manuscripts stemming from the first millennium, some of them dated, copied at the monastery of Mar Chariton and especially at that of Mar Saba, have been discovered in the monastery of St. Catherine on Mount Sinai, the only monastery that has not been pillaged and set on fire by the bedouin. These manuscripts are of great importance for the history of the Arabic language. Because Christians were less devoted to the ideal of the ‘arabiyya than their Muslim contemporaries, their writings contain a great many devi ations from classical Arabic, thus enabling us to reconstruct early Neo-Arabic, the predecessor of the modern Arabic dialects, and bridge a gap of over one thousand years in the history of the Arabic language.
