Ruskin selected this subject largely on account of Turner's handling of perspective on the right hand shore, 'which gives distance and magnitude to the Mont Pilate'. He also noted the introduction of the boat ('to keep the eye from resting on the formal oblong of the lake boundaries') and the long reflections of the blue cloud as distinctively 'Turneresque' features. Sadly, the appearance of the watercolour has changed significantly since it was selected by Ruskin. The darkening of some washes of gouache is especially noticeable in the sky. This seems to be the result of a subsequent change in the pigment used or in the medium applied, and is an effect discernible on other sheets from the same sketchbook.
