The principles of the formation of the author’s poetic ideography are highlighted — a new direction in the study of poetic texts, which is currently developing at the intersection of theoretical and practical ideography and author’s lexicography. The main goal of this approach is to identify and describe the individual author’s poetic pictures of the world and their representations in lexicographic parameters. Both the general model of the proposed poetic-ideographic analysis and the main theoretical concepts associated with the new cognitive-discursive approach to the interpretation of a poetic text are presented in the article. They are: a global individual-author’s worldview, a local picture of a fragment of the world, which in the dictionary have features their representation within the framework of various structures: integral global-event, local-fragmentary, macro- and micro-situational. They are used in the process of poetic-ideographic analysis of the poem “No, not the moon, but a bright dial...” (O. E. Mandelstam), carried out in the proposed article on the basis of the developed analysis model, its main stages, and tasks. The prospect of the research is the study of the integral individual-author’s worldview of O. E. Mandelstam, presented in the first edition of the book “Stone”, as well as the compilation of the author’s ideographic dictionary of the poet’s language.
