(b Trefonnen, nr. Llandrindod, Radnorshire [now Powys], 26 Sept. 1742; d Pencerrig, Radnorshire, 29 Apr. 1803). Welsh landscape painter, a pupil in London of his fellow Welshman Richard Wilson. He painted some ambitious classical landscapes in Wilson's manner, but he is now best known for his remarkably fresh and unaffected oil sketches done in and around Naples and Rome during a period in Italy, 1776–83 (good examples are in the National Museum, Cardiff).
