There are various issues involved in putting accurate dates to Bauernmalerei. First, the changes in furniture painting did not correspond exactly to the major movements in painting, sculpture and architecture. Rural artists moved at their own pace, as the influences of the classical schools of art were confined to the cities. These rural artisan, having only limited contact with the outside world, preserved their traditions, while at the same time, added their own inventions and styles, which varied depending on geographical location. This makes it very difficult for historians to date the furniture as the changes were slow and the styles overlapped.
