The River Thames and Windsor Castle

Cox employs a loose, fluid brushstroke that allows pigments to spread, producing a soft, almost atmospheric effect. The water’s surface is rendered with minimal detail, reflecting a pale sky dotted with faint clouds. This economical handling of colour and line emphasizes mood over precise delineation, characteristic of mid‑nineteenth‑century British watercolour practice.

Created in 1850, the piece reflects Cox’s mature period when he focused on English landscapes. While specific ownership records are limited, the drawing has been documented in catalogues of Cox’s oeuvre and is representative of his contributions to the development of atmospheric watercolour painting in Victorian Britain.
