23 all this, which has been set forth by Jason of Cyrene in five volumes, we shall attempt to condense into a single book. 24 For considering the flood of statistics involved and the difficulty there is for those who wish to enter upon the narratives of history because of the mass of material, 25 we have aimed to please those who wish to read, to make it easy for those who are inclined to memorize, and to profit all readers. 26 For us who have undertaken the toil of abbreviating, it is no light matter but calls for sweat and loss of sleep, 27 just as it is not easy for one who prepares a banquet and seeks the benefit of others. Nevertheless, to secure the gratitude of many we will gladly endure the uncomfortable toil, 28 leaving the responsibility for exact details to the compiler, while devoting our effort to arriving at the outlines of the condensation. 29 For as the master builder of a new house must be concerned with the whole construction, while the one who undertakes its painting and decoration has to consider only what is suitable for its adornment, such in my judgment is the case with us. 30 It is the duty of the original historian to occupy the ground, to discuss matters from every side, and to take trouble with details, 31 but the one who recasts the narrative should be allowed to strive for brevity of expression and to forego exhaustive treatment. 32 At this point therefore let us begin our narrative, without adding any more to what has already been said; for it would be foolish to lengthen the preface while cutting short the history itself.
