‘In the landscapes he renders precisely the darkness and illuminated splendour of the countryside, its curious and lovely melancholy and the occasional rage of it,’ wrote Osbert Sitwell of the work of painter John Piper (1903-92) at the former’s Derbyshire seat, Renishaw Hall. Such was Sitwell’s admiration for an artist credited with representing ‘the true vision of England in the mid-twentieth century’ that his patronage extended to more than seventy paintings. This year, Osbert’s nephew Sir Reresby Sitwell, has organized a third exhibition of Piper paintings from his unrivalled collection, entitled John Piper Elsewhere. Among the views are neighbouring Derbyshire houses, such as Sutton Scarsdale, above, ruined churches and the Sitwells’ Italian castle, Montegufoni.
