A forest landscape with a gorge and waterfalls

Joseph Alexander Graf Raczyński identified this painting as the work of Joos de Momper, along with a group of five other panels of the same size, each bearing the monogram 'IDM' (loc. cit.). The group consists of Italianate motifs including a Roman port, classical ruins, and mountainous landscapes reminiscent of the Alps; as such, Raczyński concluded that the paintings were conceived as a set. At the time of his publication, five of the six works remained together in the collection of the Baroness von Isbary.

The monograms on all six paintings have long been questioned, as no other works by Joos de Momper are signed in this manner. However the consistency of the monogram used across all six panels suggests that it is linked to the original commission. Klaus Ertz, despite never having evaluated this picture firsthand, included it among eleven works he considered to be by Joos's son Philips de Momper (loc. cit.). The two artists' paintings have long been confused; with further complications arising from the fact that no signed works by Philips are known. Despite slight differences in handling with paintings definitively by Joos, here the subtle atmospheric effects, the artist's use of an unblended shorthand in the depiction of distant trees and the comparatively more detailed rendering of the texture of the foreground elements suggests a close awareness of the elder artist's work.
