The study is aimed at the composition of Pavel Hruz´s book Pereat. The author of the study uses a term 'composition', which in his concept includes a structural and a thematic part of the work as well as its meaning of construction. The author's theoretical starting point is based on an idea about dynamic nature of the prose text composition, which is created by synchronic interaction of procedures providing continuity and discontinuity of the composition. The author pays attention to certain parts of Pereat's composition, which have both unifying and separating function. He describes seven texts of the book as a sequence of seven narrative transformations of the basic fabula, as seven relatively independent sujets. With their motif relations and meaning correspondence they also create logically related sequence of events, called by an ad hoc formed (subsidiary) term 'archisujet'. Narration in Pereat is composed in two levels. An effect of the whole text, not reduced to any of 'individual' texts, can be seen in oscillation between two levels. Text understanding permanently oscillates between meanings developed by particular stories and meaning belonging to an 'archisujet' layer. Distinguishing two steps of epic material transformation seems to be useful in explaining artistic value of Hruz's book as well as determinants influencing text interpretation.
