Miroslav Krleža was one of the most important 20th-century Croatian authors. The Wikipedia article about him lists several influences on his work, including "key authors like (...) Proust". However, that statement has no source and there is no similar statement (with or without a source) in the French and German Wikipedia articles about Krleža.
On Google Books, I found the following passage from Socialist Realism in Central and Eastern European Literatures under Stalin, edited by Evgeny Dobrenko & Natalia Jonsson-Skradol (Anthem Press, 2018):
The only measure of value which can be applied to a work seeking to express beauty should be that of the artist's talent, and Krleža vividly demonstrated this by the example of Proust:
Proust is a conservative snob and an overbearing bluestocking, and apart from the fact that he is a disguised royalist, he is an ingenious lyricist of psychoanalysis, a writer disproportionately more significant [...] than any left-wing and loud-voiced character of the so-called social fiction of the time.
This quote is evidence that Krleža was familiar with Proust's work, but does it constitute evidence of influence? Is there any more convincing evidence that Krleža's work was influenced by Proust's?
