25 For, considering the multitude of the books, and the difficulty that those who are willing to undertake the narrations of histories find, due to the multitude of events,
26 we have taken care, so that, indeed, those who are willing to read may have delights of the mind, and so that, in truth, the studious may more easily be able to commit it to memory, and also so that all readers may find it useful.
27 And indeed, we ourselves, who have taken up the task of abridging this work, have no easy labor. For, in truth, more correctly, we have assumed an activity full of vigilance and sweat.
28 Just as those who prepare a feast also seek to be attentive to the will of others, for the sake of the gratitude of many, we willingly undertake the labor.
29 Indeed, leaving to the authors the truths about particular details, we instead have been devoted to this form, striving to be brief.
30 For, just as the architect of a new house will have concern for the entire structure, and, in truth, he who takes care to paint it will seek out what is fitting to adorn it, so also should such things be considered by us.
31 Moreover, to collect knowledge, and to order words, and to discuss every particular point attentively, is the duty of the author of a history.
