Developed in the first decades of the 18th century in response to Limoges enamels, Chinese painted enamels on copper , or yang ci (foriegn porcelain) were produced at both Canton and the Imperial workshops in Beijing. Deemed a highly desirable curiousity in both East and West, painted enamels were often made in contemporaneous porcelain forms. These small plaques were likely destined to be table screens. Compare a set of four and a pair published by L. Vinhais and J. Welsh, China of All Colours: Painted Enamels on Copper, nos. 76 and 85, though all six show European figures in simple landscape settings. The exaggerated linear perspective of the buildings in the present set reflects the newness of this European style approach to composition in the Chinese painter's oeuvre.
