The review discusses Maciej Gloger's book *Modern Sienkiewicz*, focusing on the examination of Gloger's success in placing Sienkiewicz's creativity within a literary modernity. The book does not offer new solutions but successfully illustrates the problems that Sienkiewicz researchers face when they attempt to find a common ground between the writer's worldview and the contradictory significance of his writing. The review highlights Gloger's methodological approach, which involves a broad reflection on modernity as a complex phenomenon encompassing various cultural developments from the 18th to the 20th century. Gloger's work is situated within the context of his previous research on positivism and its role in understanding modernity. The review also discusses Gloger's reconstruction of Sienkiewicz's worldview, particularly his engagement with the concepts of modernity, conservatism, nationalism, and religion. Gloger's analysis reveals the tensions and contradictions in Sienkiewicz's thought, such as his ambivalent attitude towards positivism and his complex relationship with modernity. The review concludes that while Gloger's book is valuable for Sienkiewicz studies, it does not fully resolve the challenges of understanding Sienkiewicz's modernity.The review discusses Maciej Gloger's book *Modern Sienkiewicz*, focusing on the examination of Gloger's success in placing Sienkiewicz's creativity within a literary modernity.
