north wales in 1802

Cornelius Varley. Craig Goch, Moel Hebog, North Wales, 1802. Watercolor over graphite. 16.4 x 36.5 cm. The Metropolitan Museum, New York

This calm small watercolour of 1802 was done the year before Lusieri's Parthenon, below.  The description on the Metropolitan Museum website says that Varley left painting in favour of the development of optical instruments.  
Both are about seeing, the relationship between detail and sight, between recording and looking.
