Turner’s route to the Simplon Pass took him through the Gondo Ravine (Gondoschlucht), a narrow mountainous passage immediately to the west of the village of Gondo, which represented one of the most dramatic points on the road between Domodossola and Brig (generally considered to represent the start and finish of the Simplon road). This page depicts a view of the Gondoschlucht from the road to the east. Turner has used the full height of the page in order to convey a sense of the dramatic height and scale of the landscape. The same distinctive rock profile on the left-hand side of the composition can be seen on folio 88 verso (D14314; Turner Bequest CLXXIV 87a).
For a general discussion of Turner’s journey to the Simplon Pass see the introduction to the sketchbook, and also the introduction to the Passage of the Simplon sketchbook (Tate, Turner Bequest CXCIV).
