Another incident of less importance for Europe had, however, a more personal interest for Louis, and had already turned all the ardent piety of his inquiring spirit more and more towards the East. In the summer of 1237 he was at Compiègne, celebrating the marriage of his brother Robert, whom he had invested as knight and endowed with the province of Artois for an appanage. In the midst of the festivities people remarked with surprise that four strangers were present, men of foreign race and unfamiliar appearance, whom the King seemed to treat with great consideration. These, say the chronicles, were emissaries from the Old Man of the Mountain, the chief of an Arab sect and tribe which had sprung up in the midst of the religious, political, and warlike agitations of Islamism. This tribe had established itself in the mountains of Anti-Lebanon, between Antioch and Damascus, and its members had been known in the East for more than a century under the name of Assassins. It is said that they owed this name to the blind fanaticism with which they executed the orders of their sheikh (a word which means both chief and old man), who insured their passionate devotion to himself by all kinds of material indulgences, and made use of them to get rid of his enemies, near and far, Christian and Saracen. {47} In 1190 they assassinated Conrad, Marquis of Montserrat, then about to ascend the throne of Jerusalem, and the great Saladin himself, in spite of all his victories over the Christians, had twice nearly fallen a victim to their blows. The fame of the young King's piety and valour had reached Syria, and it was said that Louis was about to start for the East at the head of a new crusade, and to re-establish the kingdom of Jerusalem. This report caused the Old Man of the Mountain to send two of his fanatical followers to France, with orders to kill the future enemy of their country. But, on the receipt of further information, he renounced the design, and sent other two of his followers to France to prevent the execution of the murder. In this they succeeded: they not only warned Louis of his danger, but had time to return and meet the first emissaries of their master, with whom they went back to Compiègne. 'Louis, who had taken every precaution against their attempt, received them well,' say the chronicles, 'and sent them home to the Old Man of the Mountain with rich gifts.'
