This paper draws attention to the fact that east-central Sweden consisted of an extensive archipelago throughout the Stone Age. An image of the Mesolithic cultural landscape is beginning to take shape, since a large number of sites have been found and excavated in recent years. The remains of the sub-regions on the mainland and at the inner margin of the archipelago are interpreted as reflecting changes in material culture without any corresponding change further out. In considering why people of some sub-regions were more susceptible to new ideas than those of others, the specific physical setting and the strong social order prevailing in fishing and seal-hunting communities are regarded as factors which prevent rapid changes.
