Finberg listed this as one of 22 leaves from this sketchbook found ‘in a parcel labelled by Mr. Ruskin – “M. 16. Leaves of S. 229. Laid down.” They have been mounted on cartridge by Mr. Ruskin.’ Evidently, Ruskin isolated these drawings because they were pencil outlines, without the additions of chalk or gouache found elsewhere in the sketchbook.
Finberg’s idea that the drawing was made near Courmayeur seems plausible. The suggestion of a road driving directly along the valley floor from the immediate foreground is similar to the road in the watercolour St Huges Denouncing Vengeance on the Shepherd of Cormayer, in the Valley of d’Aoust (Sir John Soane’s Museum, London),1 exhibited at the Royal Academy in 1803.
