This article examines Słowacki’s preoccupation with eroticism in some of his works and in his correspondence. The first part focuses on his poem ‘In Switzerland’ in which the relationship between the characters is shrouded in ambiguity and the sexual theme is treated in an elliptical manner. Beatrix Cenci, a Romantic drama showing the fi lthy, predatory aspects of sexuality and eroticism, is analysed in the second part of the article. It is followed by a discussion of Słowacki’s correspondence with Leonard Niedźwiecki, conducted in French. The article examines the ways in which the choice of the French language appears to have infl uenced the poet’s articulation of his intimate experiences and desires.
