In West Bengali tradition, a person known as a patua travels around the countryside to entertain with sung narratives illustrated with painted scrolls. The patua’s audiences are usually poor and illiterate, lacking access to televisions and films as well as to written entertainments.
Increasingly, however, patuas are finding that their scrolls are viewed as valuable folk art, and that their storytelling skills are in demand among the urban intellectual elite as a means of selling these illustrations, which thereby take on a new, passive function.
This according to “From oral tradition to folk art: Reevaluating Bengali scroll paintings” by Beatrix Hauser (Asian ethnology LXI/1  pp. 105–122). Below, a patua demonstrates her art.
