De waterreservoirs, de zogenaamde Bends, in het bos van Belgrado
Calkoen owned a country house in Belgrade Forest, north of Istanbul. Vanmour painted that landscape, from which Vollerdt made this copy. Calkoen met Vollerdt in Dresden (his next diplomatic post), where he planned once again to acquire a large number of paintings by a single artist. He probably had Vollerdt copy Vanmour’s painting to assess his skills.
