John Ruskin was an influential critic and champion of J M W Turner and also of the Pre-Raphaelites. The influence of both Ruskin and of the Pre-Raphaelites is often cited to explain shifts in emphasis in the work of many landscape painters from the mid 19th century. Ruskin's advice to 'go to nature, rejecting nothing, selecting nothing' echoed the detailed style and techniques of the Pre-Raphaelites.
