well. 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. Neoclassicism appears rather earlier in Germany than in France, with Anton Raphael Mengs (1728–79), the Danish painter Asmus Jacob Carstens (1754–98), and the sculptor Gottfried Schadow (1764–1850). Mengs was one of the most highly regarded artists of his day, working in Rome, Madrid and elsewhere, and finding an early Neo-Classical style that now seems rather effete, although his portraits are more effective. Carstens' shorter career was turbulent and troubled, leaving a trail of unfinished works, but through pupils and friends such as Gottlieb Schick, Joseph Anton Koch and Bonaventura Genelli, more influential. Koch was born in the mountains of the Austrian Tyrol and became the leading Continental painter of landscapes, concentrating on mountain views, despite spending much of his career in Rome. Daniel Chodowiecki was born in Danzig, and at least partly identified as Polish, although he only spoke German and French. His paintings and hundreds of prints, book illustrations and political cartoons are an invaluable visual record of the everyday life and the increasingly complex mentality of Enlightenment Germany, and its emerging Nationalism. The Swiss-born Anton Graff was a prolific portraitist in Dresden, who painted literary figures as well as the court. The Tischbein family dynasty were solid all-rounders who covered most of the 18th century between them, as did the Zick family, initially mainly painters of grand Baroque ceilings, who were still active in the 20th century in the person of the illustrator Alexander Zick. Both the Asam brothers, and Johann Baptist Zimmermann
