Szukana fraza: [Abstract = Apart from the famous praefatio \(maior\), Livy's introduction to the Ab Urbe Condita as a whole, there are in the extant parts of this work four internal prologues \(or praefationes minores\), marking the beginnings of, respectively, books 2, 6, 21 and 31. In the present paper a short overview of prologues, and especially internal prologues, in ancient historiography is followed by a more detailed discussion of the four Livian passages.]
