The aim of the article is to analyze a number of indicative and interrelated examples of the reflection and duality motifs used in the novel Dead Bruges (Bruges-la-Morte) by the Belgian symbolist J. Rodenbach. The author offers a few different interpretations of these examples connecting them with the artistic and ideological horizon of art nouveau style, with its various genre manifestations, as well as in terms of the realization of its characteristic themes – femininity, death and the afterlife, water, and the urban theme.
