Samuel Palmer

The Gleaning Field, c.1833
Wikipedia - "Samuel Palmer (27 January 1805 – 24 May 1881) was a British landscape painter, etcher and printmaker. He was also a prolific writer. Palmer was a key figure in Romanticism in Britain and produced visionary pastoral paintings. ... He sketched in Devonshire and Wales around this time. His peaceful vision of rural England had been disillusioned by the violent rural discontent of the early 1830s. His small financial legacy was running out and he decided to produce work more in line with public taste if he was to earn an income for himself and his wife. He was following the advice of his father-in-law. Linnell, who had earlier shown remarkable understanding of the uniqueness of William Blake's genius, was not as generous with his son-in-law, towards whom his attitude was authoritarian and often harsh. Palmer turned more to watercolour which was gaining popularity in England. ..."
