My interest has been the ideological background of the museums. There are four museums remaining today, Stockholm 1893, Åbo (Finland) 1907, Uppsala 1910, Södertälje 1913. In the museums landscapes are represented in habitat diorama. A diorama is an arrangement of three - dimensional object and a painted background made to give a lifelike impression. In these museums you find Scandinavian biotopes reconstructed in detail; stuffed mammals, birds, reptiles, insects, bushes, plants, stones, lichen, etc.
