Very slowly and gradually the Nubians seem to have drifted from Christianity into Muhammadanism. [308] The spiritual life of their Church had sunk to the lowest ebb, and as no movement of reform sprang up in their midst, and as they had lost touch with the Christian Churches beyond their borders, it was only natural that they should seek for an expression of their spiritual aspirations in the religion of Islam, whose followers had so long borne witness to its living power among them, and had already won over some of their countrymen to the acceptance of it. A Portuguese priest, who travelled in Abyssinia from 1520–1527, has preserved for us a picture of the Nubians in this state of transition; he says that they were neither Christians, Jews nor Muhammadans, but had come to be without faith and without laws; but still “they lived with the desire of being Christians.” Through the fault of their clergy they had sunk into the grossest ignorance, and now there were no bishops or priests left among them; accordingly they sent an embassy of six men to the king of Abyssinia, praying him to send priests and monks to instruct them, but this the king refused to do without the permission of the Patriarch of Alexandria, and as this could not be obtained, the unfortunate ambassadors returned unsuccessful to their own country. [309] The same writer was informed by a Christian who had travelled in Nubia, that he had found 150 churches there, in each of which were still to be seen the figures of the crucified Christ, of the Virgin Mary, and other saints painted on the walls. In all the fortresses, also, that were scattered throughout the country, there were churches. [310] Before the close of the following century, Christianity had entirely disappeared from Nubia “for want of pastors,” but the closed churches were to be found still standing throughout the whole country. [311] The Nubians had yielded to the powerful Muhammadan influences that surrounded them, to which the proselytising efforts of the Muslims who had travelled in Nubia for centuries past no doubt contributed a great deal; on the north were Egypt and the Arab tribes that had made their way up the Nile and extended their authority along the banks of that river; [312] on the south, the Muhammadan state of the Belloos, separating them from Abyssinia. These Belloos, in the early part of the sixteenth century, were, in spite of their Muslim faith, tributaries of the Christian king of Abyssinia; [313] and—if they may be identified with the Baliyyūn, who, together with their neighbours, the Bajah (the inhabitants of the so-called island of Meroe), are spoken of by Idrīsī, in the twelfth century, as being Jacobite Christians, [314]—it is probable that they had only a few years before been converted to Islam, at the same time as the Bajah, who had been incorporated into the Muhammadan empire of the Fūnj, when these latter extended their conquests in 1499–1530 from
