On the Lledr

On the Lledr, painted in 1843 and held in Sheffield Galleries and Museums Trust, depicts the River Lledr, which flows through the valley near Betws-y-Coed in North Wales — the region David Cox had just discovered in this period. Cox's first visit to Betws-y-Coed in 1844 is sometimes dated to the year following this canvas, suggesting he may have made an exploratory earlier visit, or that the Lledr valley was accessible from nearby Conwy. The Lledr is a clear, fast-flowing river in a narrow wooded valley, quite different from the open heathland scenes Cox is equally associated with, and the challenge of rendering running water through dense riverside woodland preoccupied him across multiple works. Sheffield's museums hold a substantial Cox holding that spans his career from earlier, more topographically precise work to the loose atmospheric painting of his final decade. The 1843 date places this just as Cox's technique was reaching its most assured phase.

River scenes in wooded valleys required Cox to manage the interplay of reflected sky, moving water, and overhanging shade — a complex tonal problem he solved through broad washes of unified midtone with selective light accents. The Lledr's shallow stony bed shows through the water in places, requiring transparent paint handling over a warm ground to suggest depth without loss of clarity.
