Leon Blois, a French writer and publicist of the “end of the Belle Epoque”, the turn of the 19th and 20th centuries, left an extensive literary heritage consisting of novels, stories, polemical articles in the press, several volumes of diaries, as well as miniatures. All his texts combine rare stylistic sophistication, bizarre proto-surreal imagery and fiery Catholic piety worthy of a medieval mystic. In the center of a small collection of prose poems, masterfully translated into Russian by Alexander Chernoglazov, is a kind of monthly book, twelve visionary poems composed by Blois based on a calendar designed in the Art Nouveau style by his contemporary, engraver and designer Eugene Grasset (1845–1917) .
