Mr Pares' Coachman with a Newfoundland Dog (1823)
by
John E. Ferneley
Ferneley (1782 - 1860) — who is also identified as "John Ferneley Sr.," as his son John Ferneley Jr. was also a well-known painter (to say nothing of his son Claude Lorraine Ferneley, also an artist) — was an English painter primarily of sporting subjects, particularly race- and hunting horses. He was quite well-known and popular in his lifetime.
This is a notable work in the canon of Newfoundland represenations: it is the earliest datable work I have found which unequivocally depics a black Newfoundland.
