The article raises a question of research on children’s literature led in Poland and stemmed from Jerzy Cieślikowski’s conception that refers to the theory of fun acivities by French culture expert Roger Caillois. The authoress considers particularly useful Caillois’s essey entitled Ludzie a gry i zabawy (Le jeux et les hommes, 1958, polish translation 1973), in which he set out the typology of different kinds of jollity and provided polish researchers with a very wide questioning context. She also itroduces Cieślikowski’s concept as well as analyses the akin thoughts. Furthermore, she acquaints the reader with the effect of her own study on literature for children which is based on Caillois’s typology. She comes with her own proposals of archetypal perceptive models derived fromludic functions of literature for children.
