At Cairo, the dignity of grand-master of the lodge (Dail-doat), was frequently united by the Ismailites, with that of chief justice (Kadhi al Kodhat). As the attainment of rule was the object of the order, and as no means were left untried to accomplish it, Abulwefa sought conquest by means of treachery, and greatness by perjury. The Crusaders, whose power was continually on the increase in Syria, appeared to him the most fitting instruments of his ambitious designs. As the enemies of Mohammedanism, they were the natural allies of its most dangerous opponents. The bulwarks of the faith of Mohammed, shaken from without by the tempest of the Crusaders, and undermined from within by the atheistical doctrines of the Assassins, threatened an earlier and a more certain fall; and the pious warriors, in union with their impious allies, promised the sooner to erect the cross and the dagger on their ruins. Abulwefa entered into a treaty with the king of Jerusalem, by which he bound himself, on a certain Friday, to put the city of Damascus in his possession. While the Emir Busi, and his magnates, both courtly and military, were assembled at their devotions in the mosque, all the approaches to it were to be hemmed in by conspirators, and the gates of the city opened to the Christians. In return for this service, the king promised to deliver the city of Tyre into his power.[104] Hugo de Payens, the first grand-master of the Templars, seems to have been the principal agent in urging Baldwin II., King of Jerusalem, to this strange alliance of the cross and the dagger. For ten years after its first institution,[105] this order remained in obscurity; fulfilling, besides the usual evangelical vows of poverty, chastity, and obedience, a fourth, the protection of pilgrims; but still existing only as a private society, without statutes or knightly habits. By the code of rules given by St. Bernard, and confirmed by Pope Honorius I., it raised itself at once, to the splendour of a powerful chivalric order, for the defence of the holy sepulchre, and the protection of the pilgrims.[106] According to Miræus, its members consisted of knights, esquires, and lay-brothers, which answer to the companions (Refik), agents (Fedavi), and laymen (Lassick), of the Ismailites, as the priors, grand-priors, and grand-master, did to the Dai, Dailkebir, and Sheikh of the mountain. As the Refik were clothed in white, with red insignia, so the knights wore white mantles with red crosses; and as the castles of the Assassins arose in Asia, so did the hospitals of the Templars in Europe.
