Mountain Heights, Cader Idris

Executed with watercolor over a chalk ground, the artist applied thin, translucent washes in successive layers, allowing the underlying paper to influence the tonal values. Quick, sketch‑like brushstrokes create a sense of immediacy, while the limited palette and soft edges enhance the impression of distance and atmospheric depth.

The piece is attributed to David Cox, an English landscape painter linked to the Birmingham School and noted for his pioneering approach to watercolor during the mid‑nineteenth century. Cox’s work anticipated later Impressionist concerns with light and color, and this drawing exemplifies his early contributions to the development of English watercolor.
