It was Turner's mountain subjects that Ruskin admired above all others. He grouped these works in his catalogue after those of Venice to provide a counterpoint to their delicacy and repose, noting that Turner's depictions of rocky peaks and defiles were characterised by 'force of colour, and energy both of form and effect'. Of those exhibited here, he felt that no.72 was 'the grandest sketch in the whole series', with no.74 falling close behind. He particularly relished the way Turner had suggested the physical structure of a granite cliff: 'the pencilling along the edge of the fathest precipice, where sloping lines in an almost equi-distant succession, indicate the jags of the cliff at its most exposed angle.'
