Background. Objectives and methodology of the research. The article contains a commentary to the separate pages of A. Bennett’s diaries, in which the impressions of the famous English writer, playwright, actor and journalist from visiting the cities of Moscow, Orel and Lviv were recorded in May 1988. This trip took place at the invitation of the Writers’ Union of the USSR. As part of the British delegation, A. Bennett carried out a mission of “cultural diplomacy”, whose goal was to open the “Iron Curtain” between the West and the countries of Eastern Europe. The program of the visit of the foreign delegation is analyzed, in particular, visits to opera performances (at the Bolshoi Theater – “Werther” by J. Massenet, at the Lviv Opera and Ballet Theater – «The Ukrainian Cossack beyond the Danube» by S. Gulak-Artemovsky). The purpose of this article is to introduce into the scientific circulation the evidence that allows illuminating the events of the recent past through the prism of the perception of their immediate participants. Another task of this article is to determine the pragmatics of “hospitality” and its operatic component in the conditions of the Soviet system on a concrete example. In addition, the article establishes, with the help of diary notes, the specifics of the guests’ reaction to the realities of Ukrainian life during the “Perestroika” period and to the fact that opera represents power, which is essential for cultural diplomacy. The research is based on diary prose, which was originally prepared for publication in a literary journal. This determined the appropriate mode of expression and set the choice of illuminated objects. The descriptive-evaluative narrative appeals to real places and persons. So, the author tries to achieve the effect of documentary. At the same time, there is a noticeable tendency to create a slightly entertaining text that should interest the average reader and meet his expectations. Research results. This material made it possible to supplement with interesting facts the practice of cultural diplomacy that was established in the USSR, which was covered by the Western researchers, for example F. Barghoorn (1960), P. Hollander (1981), M. David-Fox (2011). In addition, the analysis of this evidence made it possible to introduce into scientific use not only the events, but also the attitude of foreign guests towards them. This is important for historiography and reconstruction of the recent past. The events, mentioned in the text of the evidence, acquire an outside view. The words of the “outsider” become comparative frame through which it is possible to comprehend what happened, freely from the obsessive rhetoric of the perestroika time. According to Bennett, in 1988 the protective function of the totalitarian system came into conflict with the new trend of the time. The imprint of stagnation and decline, even decomposition, but not the sense of purpose and optimism, which P. Hollander described as the “stigma of these countries”, also affected the “window” of Soviet reality, where obvious cracks of loud selfdisclosures appeared. The mandatory program of the visit included meeting with colleagues. With the help of diary, the specific reaction of the guests is set to the fact why an opera self-representation was so important for the «Soviet side». The pages of Bennett’s diaries showed attention to everyday details. The writer was able to create not an image of faceless mass, but the vivid portraits of his contemporaries and capture his experience of meeting a different reality. Conclusions. A. Bennett – a man and a writer – recreated his short stay in Lviv, capturing the theatrical nature of the life-giving performance that unfolded here in the tense collisions between official rhetoric and living reality. The opera itself was of little interest to A. Bennett, but he was well aware of the exceptional importance attached by the organizers of the trip to the fact of visiting the opera house. As an “object of showing” to foreigners, the opera served, first of all, as a proof of the “culture” of the country, a proof that the cultural heritage of the past is better preserved here. At the same time, in the system of “cultural diplomacy” the opera topos functioned as an aesthetic representation of power, the “higher truth” about it. Opera representation existed as a self-sufficient complete phenomenon, which testified to the presence of higher meanings in the real world.
