Johann Christian Vollerdt, Jean Baptiste Vanmour – De waterreservoirs, de zogenaamde Bends, in het bos van Belgrado, 1744-1763 Rijksmuseum: part 3

This painting depicts a vast, tranquil landscape dominated by rolling, tree-covered hills under a pale, cloudy sky. In the foreground, a large body of water, likely a reservoir, stretches into the distance.
A prominent man-made structure, a stone aqueduct or dam, runs diagonally across the middle ground on the left. Water cascades from it, suggesting its function in managing the reservoirs flow. Several small figures are scattered along this structure and the surrounding grassy bank, some engaged in leisurely activities like picnicking or riding horses, while others appear to be tending to the structure itself.
On the water, a person in a small boat can be seen, and a pair of swans glide serenely. The far bank of the reservoir is lined with a dense, formal arrangement of trees, creating a strong visual line that leads the eye into the more distant, undulating hills. In the far distance, nestled amongst the hills, are hints of buildings, suggesting a settlement or estate.
The overall atmosphere is one of peaceful contemplation of nature, enhanced by the soft light and the serene water. The inclusion of human figures interacting with the landscape and the impressive aqueduct highlight the relationship between human engineering and the natural world. The painting could be interpreted as a celebration of the control and appreciation of natural resources, as well as a testament to the beauty of the landscape itself, perhaps reflecting the Enlightenment ideals of order, reason, and the sublime in nature.
