ENThe article analyzes Blūdas (Obsession, 1912) by the Lithuanian writer Julijonas Lindė-Dobilas, the first Lithuanian psychological novel, which clearly focuses on the subjective issues of man, his conscious and subconscious processes, and which stood out for its artistry in the context of Lithuanian prose at the time. The novel is characterized by the features of Modernism: fragmented narrative, the psychological process of the subject becomes the content of the narrative, the importance of reminiscences becomes significant. Blūdas is a work in which, for the first time in a Lithuanian novel, plastic and living pictures of people are created, character, behaviour, and actions are motivated. However, in many senses, it remains connected with the common imperatives of Lithuanian prose self-awareness of that time: active attention to community issues, the most relevant topics of public life, remaining an undoubted educator of public consciousness. The protagonist in the novel embodies the cultural reflections of the 20th century, he is characterized by a cultural identity to be a good Lithuanian and a good Catholic, which takes precedence over human identity. Key words: Lithuanian modern novel, Julijonas Lindė-Dobilas, identity.
