In cognitive linguistics metaphorical mapping is a way of reconstruction of the author’s mental models of the figurative perception of the world. The author of the article reveals metaphorical mappings of W. Churchill’s “Fulton speech” according to conceptual metaphor theory (CMT). The material for studying is the archive original typescript of the speech, scrawled by W. Churchill. While studying the archive documents the author of the article deals with both linguistic and extralinguistic data. The analysis of the metaphoric mappings of “Fulton speech” is implemented in the article with the consistent process of interpretation. The research has shown that metaphoric, deep-structural author’s thought is understood if metaphorical mappings are interpreted by means of the event context. According to contextual interpretation of the conceptual metaphors from W. Churchill’s “Fulton speech” the author draws the following conclusions: the mapping “World”-“Theatre” is associated with the post-war period of contemporary history; “World” - “Illness”, “World” - “Crime” correspond to conceptual perception of war; “World” - “Religion”», “World» - «Earth” are mentally perceived out of time. The value of the investigation is inter-disciplinary as its results deal with linguistics, history, hermeneutics and rhetoric.
