Kozma Prutkov is the most unique satirist of the 19th century, mocking the morals and foundations of his era and dispensing memorable ringing slaps to public taste. The unusualness of Kozma Prutkov was manifested not only in the style and content of his works. This outstanding man himself is one of the most remarkable literary inventions: his pedigree, biography and work are completely invented by several original writers - the Zhemchuzhnikov brothers, Pyotr Ershov and Alexei Tolstoy. The book includes the collections "Leisure" and "Down and Feathers", containing the most poignant immortal aphorisms, socio-political projects, parody poems and fables by Kozma Prutkov. The book also includes “Extracts from the Notes of My Grandfather” - anecdotal cases and “historical materials” proving that Kozma Prutkov’s grandfather had no less literary talents than his outstanding grandson , biographical information about the personality and life milestones of Prutkov Jr., a short obituary on his death, as well as a unique posthumous work dictated by him during a spiritualistic seance.
