Touching the individual known as the Bab and the true nature of this sect diverse tales are on the tongues and in the mouths of men, and various accounts are contained in the pages of Persian history and the leaves of European chronicles. But because of the variety of their assertions and the diversity of their narratives not one is as worthy of confidence as it should be. Some have loosed their tongues in extreme censure and condemnation; some foreign chronicles have spoken in a commendatory strain; while a certain section have recorded what they themselves have heard without addressing themselves either to censure or approbation. (3:1)
Now since these various accounts are recorded in other pages, and since the setting forth thereof would lead to prolixity, therefore what relates to the history of this matter (sought out with the utmost diligence during the time of my travels in all parts of Persia, whether far or near, from those without and those within, from friends and strangers), and that whereon the disputants are agreed, shall be briefly set forth in writing, so that a summary of the facts of the case may be at the disposal of those who are athirst after the fountain of knowledge and who seek to become acquainted with all events.
