"The Landscape with Ruins" painting is a vivid example of the artist's imaginary landscapes, in which he combined real landscape elements with imaginary ruins of buildings. The genre of architectural "capriccio", or the images of imaginary architectural views, became extremely popular among collectors in the 18th century, which contributed to the spread of these images throughout Europe. The artist depicted the fictional ruins of a castle against the background of a mountain landscape with a river flowing past it. The painter added figures of peasants doing their daily business to supplement the picture. Although Franz Christoph Janneck mostly executed his paintings on copper, this work was done on a board.
