Of far more importance than any of the artists mentioned in the foregoing paragraph is Paul Sandby,[634] who, as has already been indicated, was the first to make known to art the wild and beautiful scenery of the Scotch Highlands. In 1773 he exhibited his first Welsh picture, and after that he did much work in Wales. Though not the first to paint in that region--for Boydell, Wilson, Farington, and Devis were ahead of him--he yet did much to show its picturesque possibilities. His important Welsh “aquatint views taken on the spot” appeared in four sets of twelve plates each, beginning in 1775, the very year of Boydell’s publication of Wilson’s “Six Views.” These mountain pictures, especially those of the second series, justly rank as the most vital landscape work contemporary with Wilson and Gainsborough. “Llangolin in Denbigh,” “Conwyd Mill,” “Llanberis Lake and Great Mountain Snowdon,” “Pont-y-Pair over the River Conway” are but a few of the many pictures that show with what enthusiasm Sandby surrendered himself to impressions from the grand scenery of Wales. The striking change from early eighteenth-century topographical sketches where the building was merely rendered slightly more attractive by washed-in skies and greensward is evidenced by such pictures as Sandby’s “Wynnestay, Seat of Sir Watkins William Wynne” which is a pure landscape with no house visible. So, too, in “Chirk Castle” there is but the faintest indication of the castle in the distance. Sandby’s original purpose may have been topographical but the outcome was pure landscape of great interest and significance.
