Art of Germany

Part Two
Dream and Machine

 The Baroque and Rococo periods saw German art producing mostly works derivative of developments elsewhere, though numbers of skilled artists in various genres were active. The period remains little-known outside Germany, and though it "never made any claim to be among the great schools of painting", its neglect by non-German art history remains striking. Many distinguished foreign painters spent periods working in Germany for princes, among them Bernardo Bellotto in Dresden and elsewhere, and Gianbattista Tiepolo, who spent three years painting the Würzburg Residence with his son. Many German painters worked abroad, including Johann Liss who worked mainly in Venice, Joachim von Sandrart and Ludolf Bakhuisen, the leading marine artist of the final years of Dutch Golden Age painting. In the late 18th century the portraitist Heinrich Füger and his pupil Johann Peter Krafft, whose best known works are three large murals in the Hofburg, had both moved to Vienna as students and stayed there.
