The goal of this paper is to draw attention to the problems connected with the editing of old sources. The author shows through various analyses, to what significant extent a mere presentation of the material becomes its interpretation and imposes one or another understanding – and that it is the historical moment that determines how the source is researched. The author presents the newest studies, where the genetic multilayeredness of the text was taken into account and resulted in a different approach and a more attentive reading.
