Ivan Bunin's books have been translated into many languages, and the world's leading writers praised his gift. Romain Rolland called Bunin an "artistic genius"; he was spoken and written of in much the same vein by writers like Henri de Régnier, Thomas Mann, Rainer Maria Rilke, Jerome K. Jerome, and Jarosław Iwaszkiewicz. In 1950, on the eve of his 80th birthday, François Mauriac expressed in a letter his delight and admiration, but also his deep sympathy to Bunin's personal qualities and the dignified way he'd got through all the tremendous difficulties life had thrown at him. In a letter published by Figaro André Gide greeted Bunin "on behalf of all France", calling him "the great artist" and adding: "I don't know of any other writer... who's so to the point in expressing human feelings, simple and yet always so fresh and new". European critics often compared Bunin to both Tolstoy and Dostoyevsky, crediting him with having renovated the Russian realist tradition both in essence and in form.
