Hitherto, the Ismailites had only Masters and Fellows; namely, the Dais or emissaries, who, being initiated into all the grades of the secret doctrine, enlisted proselytes; and the Refik, who, gradually intrusted with its principles, formed the great majority. It was manifest to the practical and enterprising spirit of Hassan, that, in order to execute great undertakings with security and energy, a third class would also be requisite, who, never being admitted to the mystery of atheism and immorality, which snap the bonds of all subordination, were but blind and fanatical tools in the hands of their superiors; that a well organized political body needs not merely heads but also arms, and that the master required not only intelligent and skilful fellows, but also faithful and active agents: these agents were called Fedavie (_i. e._ the self-offering or devoted), the name itself declares their destination. How they afterwards, in Syria, obtained that of the Hashishin or Assassins, we shall explain hereafter, when we speak of the means employed to animate them to blind obedience and fanatical self-devotion. Being clothed in white,[55] like the followers of Mokannaa, three hundred years before, in Transoxana, and, still earlier, the Christian Neophytes, and, in our own days, the pages of the sultan, they were termed Mobeyese, the white, or likewise, Mohammere the red, because they wore, with their white costume, red turbans, boots, or girdles, as in our own day do the warriors of the prince of Lebanon, and at Constantinople the Janissaries and Bostangis as body guard of the seraglio. Habited in the hues of innocence and blood, and of pure devotion and murder, armed with daggers (cultelliferi) which were constantly snatched forth at the service of the grand-master, they formed his guard, the executioners of his deadly orders, the sanguinary tools of the ambition and revenge of this order of Assassins.
