Though few members of the public give much thought to ranking the prestige of different art forms, if forced to do so it is likely that watercolour painting would be granted an affectionate but decidedly second-tier status. We think of pretty landscapes formed with washed-out pigments: light browns, greens, yellows, pinks and reds that tend to pink, of Englishmen in sunhats sitting patiently in a field, enjoying a hobby for idle gentlemen. Meanwhile, in a stratum below all of this lies our childhood memories of dipping thin brushes in water, rubbing them against coins of hard paint, and applying the resultant mixture to soggy paper.
There is some truth to all of this, but it is at best a half-truth. The late eighteenth and early nineteenth centuries saw the emergence of painters who used watercolours to sublime effect: Thomas Girtin, John Constable, and J.M.W. Turner – who produced three times as many paintings based on watercolours as on oils — elevated landscape art to a position of dominance, at least for a time. Lesser known today but judged by earlier critics to have been one of the most innovative and artistic of the watercolourists was John Sell Cotman (1782-1842).
