The editors of the Library Edition
describe the image as a “a sketch of a calm, broad river: on one side, a rocky road; on the other, crags”
(Ruskin, Works, 2:349 n. 1).
A solitary rider on horseback follows the road, moving away from the viewer.
See, in the poem " target="_self">“The sky was clear, the morn way gay” [“The Meuse”],
the lines “Peak over peak, fantastic ever / The lofty crags deep chasms sever. / And grey and gaunt their lichened head /
Rose sheerly from the rivers bed“ along with accompanying gloss.
