The _Fihrist_, _i.e._, Catalogue, is a sort of history of literature made in the eleventh century by the Moslem historian An Nadim. In spite of its late date, it is the most important authority for the original doctrines of Mani and the facts of his life, as it is largely made up from citations from ancient authors and writings of Mani and his original disciples. (_a_) The Life of Mani. Mohammed ibn Isak says: Mani was the son of Fatak,(84) of the family of the Chaskanier. Ecbatana is said to have been the original home of his father, from which he emigrated to the province of Babylon. He took up his residence in Al Madain, in a portion of the city known as Ctesiphon. In that place was an idol’s temple, and Fatak was accustomed to go into it, as did also the other people of the place. It happened one day that a voice sounded forth from the sacred interior of the temple, saying to him: “Fatak, eat no flesh, drink no wine and refrain from carnal intercourse.” This was repeated to him several times on three days. When Fatak perceived this, he joined a society of people in the neighborhood of Dastumaisan which were known under the name of Al-Mogtasilah, _i.e._, those who wash themselves, baptists, and of whom remnants are to be found in these parts and in the marshy districts at the present time. These belonged to that mode of life which Fatak had been commanded to follow. His wife was at that time pregnant with Mani, and when she had given him birth she had, as they say, glorious visions regarding him, and even when she was awake she saw him taken by some one unseen, who bore him aloft into the air, and then brought him down again; sometimes he remained even a day or two before he came down again. Thereupon his father sent for him and had him brought to the place where he was, and so he was brought up with him in his religion. Mani, in spite of his youthful age, spake words of wisdom. After he had completed his twelfth year there came to him, according to his statement, a revelation from the King of the Paradise of Light, who is God the Exalted, as he said. The angel which brought him the revelation was called Eltawan; this name means “the Companion.” He spoke to Mani, and said: “Separate thyself from this sort of faith, for thou belongest not among its adherents, and it is obligatory upon you to practise continence and to forsake the fleshly desires, yet on account of thy youth the time has not come for thee to take up thy public work.” But when he was twenty-four years old, Eltawan appeared to him and said: “Hail, Mani, from me and from the Lord who has sent me to thee and has chosen thee to be his prophet. He commands thee now to proclaim thy truth and on my announcement to proclaim the truth which is from him and to throw thyself into this calling with all thy zeal.”
