In the context of Sentimentalism in the 1770s, literary culture opened up to representations of human subjectivity. The chapter considers genres of poetry devoted to the themes of pleasure, death, and posterity. It also considers the spaces of poetry and modes of exchange, whether through the album, the salon, and the verse epistle. Two case studies explore the use of different literary forms in the further development of identity, individual and also authorial. The first looks at Radishchev’s experiment in writing a fictional diary as a psychological exercise. The second examines the tradition of imitation of Horace’s Monument poem in Russian poetry in the eighteenth century as well as by later poets, such as Pushkin and Brodsky. The case study shows how these Russian versions express changing ideas about imitation and originality as well as poets’ concern with posterity.
