The founder of the Fatimite dynasty of the Khalifas was one Ubeidallah, known as the Mahdi, accused of Jewish ancestry by his adversaries the Abbasides, who declared--apparently without truth--that he was the son or grandson of Ahmed, son of Adbullah ibn Maymūn, by a Jewess. Under the fourth Fatimite Khalifa Egypt fell into the power of the dynasty, and, before long, bi-weekly assemblages of both men and women known as "societies of wisdom" were instituted in Cairo. In 1004 these acquired a greater importance by the establishment of the Dar ul Hikmat, or the House of Knowledge, by the sixth Khalifa Hakim, who was raised to a deity after his death and is worshipped to this day by the Druses. Under the direction of the Dar ul Hikmat or Grand Lodge of Cairo, the Fatimites continued the plan of Abdullah ibn Maymūn's secret society with the addition of two more degrees, making nine in all. Their method of enlisting proselytes and system of initiation--which, as Claudio Jannet points out, "are absolutely those which Weishaupt, the founder of the _Illuminati_, prescribed to the 'Insinuating Brothers'"[129]--were transcribed by the fourteenth-century historian Nowairi in a description that may be briefly summarized thus[130]: The proselytes were broadly divided into two classes, the learned and the ignorant. The Dai was to agree with the former, applauding his wisdom, and to impress the latter with his own knowledge by asking him perplexing questions on the Koran. Thus in initiating him into the first degree the Dai assumed an air of profundity and explained that religious doctrines were too abstruse for the ordinary mind, but must be interpreted by men who, like the Dais, had a special knowledge of this science. The initiate was bound to absolute secrecy concerning the truths to be revealed to him and obliged to pay in advance for these revelations. In order to pique his curiosity, the Dai would suddenly stop short in the middle of a discourse, and should the novice finally decline to pay the required sum, he was left in a state of bewilderment which inspired him with the desire to know more. In the second degree the initiate was persuaded that all his former teachers were wrong and that he must place his confidence solely in those Imams endowed with authority from God; in the third he learnt that these Imams were those of the Ismailis, seven in number ending with Mohammed, son of Ismail, in contradistinction to the twelve Imams of the Imamias who supported the claims of Ismail's brother Musa; in the fourth he was told that the prophets preceding the Imams descending from Ali were also seven in number--namely Adam, Noah, Abraham, Moses, Jesus, the first Mohammed, and finally Mohammed son of Ismail.
