From this time onwards references to renegades are not infrequently to be met with in the writings of those who travelled to the Holy Land and other countries of the East. The terms of the oath which was proposed to St. Louis by his Muhammadan captors when he was called upon to promise to pay the ransom imposed upon him (A.D. 1250), were suggested by certain whilom priests who had become Muslims; [236] and while this business of paying the ransom was still being carried on, another renegade, a Frenchman, born at Provins, came to bring a present to the king: he had accompanied King John of Jerusalem on his expedition against Damietta in 1219 and had remained in Egypt, married a Muhammadan wife and become a great lord in that country. [237] The danger of the pilgrims to the Holy Land becoming converts to Islam was so clearly recognised at this time that in a “Remembrance,” written about 1266 by Amaury de la Roche, the master of the Knights Templar in France, he requests the Pope and the legates of France and Sicily to prevent the poor and the aged and those incapable of bearing arms from crossing the sea to Palestine, for such persons either got killed or were taken prisoners by the Saracens or turned renegades. [238] Ludolf de Suchem, who travelled in the Holy Land from 1336 to 1341, speaks of three renegades he found at Hebron; they had come from the diocese of Minden and had been in the service of a Westphalian knight, who was held in high honour by the Soldan and other Muhammadan princes. [239] These scattered notices are no doubt significant of more extensive conversions of Christians to Islam, of which no record has come down to us: e.g. there were said to be about 25,000 renegades in the city of Cairo towards the close of the fifteenth century, [240] and there must have been many also to be found in the cities of the Holy Land after the disappearance of the Latin princedoms of the East. But the Muhammadan historians of this period seem to have been too busily engaged in recording the exploits of princes and the vicissitudes of dynasties, to turn their attention to religious changes in the lives of obscure individuals; and (as far as I have been able to discover) they as little notice the conversions of Christians to Islam as of those of their own co-religionists to Christianity. Consequently, we have to depend for our knowledge of both of these classes of events on Christian writers, who, while they give us detailed and sympathetic accounts of the latter, bear unwilling testimony to the existence of instances of the former and represent the motives of the renegades in the worst light possible. The possibility of any Christian becoming converted to Islam from honest conviction, probably never entered into the head of any of these writers, and even had such an idea occurred to them they would hardly have ventured to expose themselves to the thunders of ecclesiastical censure by giving open expression to it.
