The image of a country has a critical impact on the degree of its political, economic and cultural influence in the world. This indicates a need to understand various perceptions of a country that exist among other nations and mechanisms of their formation and change in an ever-shifting world. This qualitative case study seeks to examine the changing nature of wild animal metaphors employed to model the image of Russia in American media discourse in the XIX-XXI centuries. The study is limited by two source domains, namely, the beast and the bear. They were analyzed within particular contexts: American English, culture and media discourse. The research data were drawn from dictionaries and corpora. The dictionaries included etymological and explanatory entries, as well as those covering idioms, symbols, and metaphors. The corpora research data were collected from the Corpus of Contemporary American English and Chronicling America, a collection of historic digitalized texts. A total of 218 metaphors were selected from 4929 texts. The metaphors were studied through lexicographic, conceptual metaphor, culture-specific, corpus, discourse, and diachronic methods. The findings of this study suggest that the two metaphors “Russia is a beast” and “Russia is a bear” are frequently used in realizing the strategy of ‘othering’ in XXI century American media discourse. Still, their meanings allowed for variation and modification in the periods of the two countries’ amity and cooperation. In the XIX century and in the years of US-Soviet alliance in WWII the metaphors could evoke positive images of Russia, thus, realizing the strategy of ‘bridging’ or ‘belonging’. The contribution of this study has been to confirm that, whatever metaphorical projections exist in language and culture, historical factors determine choices in any sample of discourse. This could be important for understanding the mechanisms involved in modeling the image of modern Russia in foreign media discourses.
