THE ISOPLASM IN CONCEPT OF TEMPORALITY IN LITERARY TEXTS IN THE VIEW OF THE GROUP 'mu' (Pojecie izoplazmii w koncepcji czasowosci tekstu poetyckiego Grupy 'mu')

The notion of poetic text temporality proposed by Group 'mu', and in particular its key element – isoplasm – offers interesting and relatively little known instruments for analysis of temporal aspects in poetry. Ispolasm is seen as phonic redundancy, i.e. repetition of a sound or a set of sounds in a text manifested on the level of expression. Expressed in different forms (protorhythm, quasi-rhythm, rhythm), depending on the number of repetitions of the element, such redundancy directs into the text a specyfic order, cyclicity, regularity, and thus puts the expressed content into some temporal clamps. The approach discussed in the present article is illustrated with an analysis of Jan Lechon's poem 'Liliacs in Pennsylvania' ('Bzy w Pensylwanii'), in which the stress is put on the isoplasm in question as well as on the semantic effects it produces in the text.
