The valley of the Manzanares river, Spain: a rural landscape with goatherds. Engraving by S. à Bolswert after Sir P.P. Rubens.

The painting is described by Adler as follows (left and right have to be reversed for the engraving): "The Bolswert engraving (Fig. 105) shows in reverse the valley of the Manzanares flowing towards Madrid. The tree-lined river winds out to the left from behind a heavily wooded hill in the distance, and disappears not long afterwards beyond the left edge of the picture. On the broad hillside are buildings resembling villas and castles, and around them a wide area of the lonely-looking country is surrounded by a wall. The ground is riven by deep rocky clefts and canyons, and the tops of trees growing in these crevices are seen above the surface. The mountains of Castile rise in the background. The panorama, seen from a high viewpoint, is surmounted by a large expanse of cloudy sky. In addition there is a large cloud bank below, near the mountain-peaks in the background, and detached round clouds extend diagonally leftward into the foreground, leading the eye into the distance. On the nearer part of the hill, goats are grazing at the edge of a rocky slope. Far below, on the left, a flock of sheep with two shepherds, one mounted, is moving from the foot of the hill to the lowest part of the valley, where there is a row of tall poplars; their regular shadows fall to the right, as do those of the trees and bushes higher up. The time seems to be evening. The Castilian mountain landscape with its austere grandeur impressively dominates the scene despite the Baroque treatment typical of Rubens."--Adler, loc. cit.
