Few examples of the Mahdtan expectancy survive from the time prior to the coming of Paul Muad'Dib to Arrakis (Raids). Even the records of Princess Irulaa remain fragmentary and some chapters of the Orange Catholic Bible indicate that the power of messianic imagery was felt in the most ancient religious conceptions. The Mahdtan expectancy in these texts often seems to combine spiritual with warlike components. Evidently any harsh* ness of existence seems to promote a Utopian mentality which in turn seeks a total solution to unlivable circumstances. For this solution to emerge, a solitary figure of heroic proportions must provide absolute leadership. Comparative interplanetary socio-hist one research has produced a significant body of well-founded mathematical data on the crucial transformational point at which a people will yearn for "Mahdi surrender.** It has even been suggested that the ancient Bcne Gesserit were able to use some of the earliest scholarship in this area to develop their "Missionaria Protectiva," but mis concept has been disputed in the literature. Kreber's now classic work, SocSystem of the Bene Gesserit (Diana; Tevis) suggests that they operated in the earliest millennia without use of scholarly materials.
