The paper is devoted to one of the most famous works by Giuseppe Verdi – “Requiem”. The author traces the history of its creation, associated with the death of Alessandro Manzoni, the renowned writer of Risorgimento era, whose novel “The Betrothed” became a milestone in the history of Italian literature and made a huge impression on young G. Verdi. In this connection, the authors of the paper for the first time ever in Russian musicology put forward and justify the idea that the Manzoni’s novel images are close to the Verdi’s requiem mass, by presenting analytical observations of literary and musical works. Dramatic composition of the novel and Requiem is based on the interaction of several image lines: lyrical-psychological, heroic-patriotic and religious. In addition, the historical parallels are found between the time of the novel, and the era when “the maestro of Italian revolution” lived. The authors also explained the reasons for which in the 19th century it became possible for the related arts to penetrate into the spiritual composition.
