The article deals with the relationship between Karol Irzykowski and Stefan Grabiński. Its main part was based on the correspondence of the author of Pałuba (The Hag) with many influential men of letters in interwar Poland. In these letters and in his diary of 1916-1944 one can find a lot of information shedding new light on the critic’s relationship with Grabiński. They show a gradual process of forming an acquaintance that with time grew into a friendship. Grabiński’s literary work was also an artistic inspiration for Irzykowski, who, after reading The Motion Demon, wrote a short story called Astral Carriage (briefly discussed in this article). For about twenty years Irzykowski was a spiritual patron of Grabiński’s career, promoting his work, however he was by no means uncritical towards the writer (what proves it is his review of Grabiński’s novel Baphomet’s Shadow). The article also includes a brief discussion of Irzykowski’s project related to The Writers’ Chamber which Grabiński was to become a member of, and recalls the effort of Irzykowski together with J. E. Płomieński to grant the author of The Salamander The Literary Award of the City of Lvov.
