Watch soap2day. A ritual vase, the hampi, is placed in the center of the Musée de plein air de la République du Niger in Niamey, during a ritual ceremony featuring possession dances. With this film, Jean Rouch continues his ethnological and cinematographic study of Songhay ritual objects. He demonstrates that, in a particular context, the transfer of a hampi vase to a museum requires the organization of a ritual ceremony to obtain the gods' approval. At the time, however, reservations about filming a possession dance for the opening of a shrine in a museum made the move "questionable from a museological point of view".
