February 6 to May 3, 2015
An exhibition by Nasjonalmuseet Oslo, Norway and
Staatliche Kunstsammlungen Dresden at the Albertinum
Caspar David Friedrich (1774–1840) and Johan Christian Dahl (1788–1857) are regarded as the leading figures of Nordic landscape painting in the Romantic era. The city of Dresden provided these two great innovators with a stimulating environment where their art could develop and flourish. Here, in their adopted homeland, they shared a house for almost 20 years, passing on their pioneering artistic approach to a generation of younger artists.
