The article discusses Maria Dabrowska’s and Stanislaw Stempowski’s contacts with a Russian critic Dmitry Filosofov in the period of Filosofov’s stay in Poland in 1920s and 1930s. Minor figures of the relations are Jerzy Stempowski and Filosofov’s close collaborators. The main source are Filosofov’s letters to Dabrowska and to Stanislaw Stempowski, which offer a testimony to their profound friendship and deep ideological and mental disparities. An important thread of the research is the process of composing of Night and Days which Filosofov greatly appreciated, keeping a distance from Dabrowska’s journalistic commentaties. However they were open, tolerant, and their views on their home cultures proved to be far from radically nationalistic, there were also misunderstandings between them following from the traditional Polish-Russian controversies. In the final analysis, the misunderstandings failed to conceal their true friendship and intellectual conformity.
