In this paper, we describe an attempt to apply the concept of dominant meaning by V.A. Pishchalnikova for the Descriptive Approach to study the relationship between the poetic text and its self-translation on the example of self-translations by J. Brodsky. V. A.  Pishchalnikova points directly to the need to develop a theory of translation based on conceptual analysis, “when the content of the text is presented as a function field of meaning, rather than verbal actualization of the semantic field of a lexeme, it should be studied the relationship of the components of the dominant meaning of the text, represented in different lexemes which do not usually implement an abstract systemic meaning, but fix actual author’s subjective meanings using conventional units”. A significant part of reconstructed personal meanings of poetic texts by J. Brodsky are aestheticised emotions. The technique proposed by Pishchalnikova allows to present the cognitive structure of each literary text as a set of cognitive features (including the relationship between these features). The analysis of correlation of semantic schemes of original text and the translation of the poem by J. Brodsky proves the relations of isomorphism (the identity of the form of original text and self-translation, where the form means formal-explicable personal meaning, according to the method by V. A. Pishchalnikova).
