Caernarvon Castle by Moonlight

This 1780 painting of Caernarvon Castle by moonlight combines Wright's fascination with Welsh castles, which he visited on several tours, with his signature moonlight effects. The ruined medieval castle illuminated by silver moonlight embodied the growing taste for picturesque and sublime landscapes. Joseph Wright of Derby's landscapes combine topographical observation with the atmospheric interests that were central to all his work. His landscapes of the Derbyshire Peak District, the Welsh mountains, and the Italian campagna are distinguished by the quality of light — natural this time, but observed with the same attention he brought to candlelight and volcanic fire. His Derbyshire landscapes participated in the emerging Romantic tradition of the British landscape as a subject of aesthetic and emotional significance, the industrial transformations of his home region (the Arkwright mills, the lead-smelting furnaces) providing material for a new kind of landscape that was simultaneously documentary and sublime.

The moonlit castle demonstrates Wright's mastery of nocturnal light effects, with silvery illumination picking out architectural details against a dark sky and reflected in still water below.
