The neglect of chronology by the oriental historians, or their European translators and followers, is frequently such that we are left in great uncertainty as to the exact time of particular events, and are thus unable to trace them to their real causes and occasions. The mention of the earthquake of 1157 would however seem to make it probable that it was about that time that Sinan put forward his claims to divinity; and as, at that very period, Hassan, the son of Keäh Mohammed, was giving himself out for the promised imam, we may suppose that it was his example which stimulated Sinan to his bold attempt at obtaining independent dominion over the Syrian branch of the Ismaïlites. Sinan was, like Hassan, a man of considerable learning. His works are held in high estimation by the remains of the sect of the Ismaïlites still lingering among the mountains of Syria. These works, we are told, consist of a chaotic mixture of mutilated passages of the Gospel and the Koran, of contradictory articles of belief, of hymns, prayers, sermons, and regulations, which are unintelligible even to those who receive and venerate them. The sacred books of the Christians formed, as we see, a part of the studies of the Sheikh of Massyat, and, as it would appear, he thought he might derive some advantage from his acquaintance with them. The religio-military society of the Knights of the Temple, whose history we shall soon have to record, had possessions in the neighbourhood of those of the Assassins, and their superior power had enabled them, at what time is uncertain, to render the latter tributary. The tribute was the annual sum of 2,000 ducats, and Sinan, to whom probably all religions were alike, and who had unbounded power over the minds of his people, conceived the idea of releasing himself from it by professing the same religion with his neighbours. He accordingly sent, in the year 1172, one of his most prudent and eloquent ministers on a secret embassy to Amalric King of Jerusalem, offering, in the name of himself and his people, to embrace the Christian religion, and receive the rite of baptism, provided the king would engage to make the Templars renounce the tribute of 2,000 ducats, and agree to live with them henceforward as good neighbours and friends and brethren. Overjoyed at the prospect of making converts of such importance, the king readily assented to the desires of the Ismaïlite chief, and he at the same time assured the Templars that their house should not be a loser, as he would pay them 2,000 ducats annually out of his treasury. The brethren of the Temple made no objection to the arrangement: and after the Ismaïlite ambassador had been detained and treated honourably for some days by the king, he set out on his return, accompanied by a guide and escort sent by the king to conduct him as far as the borders of the Ismaïlite territory. They passed in safety through the country of Tripolis, and were now in
