Russia is the largest country on earth, unimaginably vast. Its people naturally have a great attachment to their country – and its landscape – in spite of their turbulent history, and in the late 19^th century painters portrayed with deep feeling their native environment, their feelings for the motherland perhaps intensified among the more sophisticated the more they had travelled and studied in Europe. 

There’s movement towards a walk after lunch, but by the time everyone’s hummed and hawed about where they might go, rubbed their bellies after one too many forcemeat balls and argued about who put the Guardian Quiz where, it’s already dark and there’s only you and one other still up for it. They cry off – a mercy – and you’re alone, heading out across the garden, along the path towards the headland. As you crest the dark bank you’re hit by freezing wind and the radiance of the moon’s path across the icy sea.

Pre-Raphaelites, eat your heart out; and wherever he is, John Ruskin, once so dismissive of the artist, must be beaming with pleasure. The American landscape painter Frederic Church (1826-1900) was indeed seen as the heir to Turner, and his distinct landscape idiom is encapsulated by a handful of oil sketches – just over two dozen – of scenes from the Hudson River Valley to Petra, Ecuador to Newfoundland, Bavaria to Salzburg, Jamaica to Labrador. 

Prunella Clough, 1919–1999, was one of the most idiosyncratic and original British artists of the postwar period. Her art is reticent, shy, subtle - yet in both life and aesthetics she was a free and generous spirit. Now there is a fine selection of works large and small, but all domestic in size, on view in the West End, marking the publication of a magisterial new biography by Frances Spalding.

Graham Sutherland and George Shaw have two things in common. They are both painters and both are associated with Coventry: Sutherland made his famous altarpiece work – a tapestry –  for the city’s rebuilt cathedral, while Shaw grew up in Coventry’s Tile Hill, a housing estate that’s become familiar to us through Shaw’s beautiful and melancholy Humbrol enamel oil paintings.

For dull reasons to do with a dodgy digital box and a very old analogue telly, I can’t tune in to BBC Four during live transmissions, so I either catch up on iPlayer, or (lucky me as a journalist) get to see programmes early. But I’m very glad I can get it at all, for when the BBC cuts come to pass and its premier arts channel starts broadcasting archive-only material, as it proposes to do, then I think I might just stop watching telly altogether.

Dogs, horses, cows, sheep, goats and pigs are the creatures that, however minuscule in stature, take pride of place in the fascinating exhibition of Thomas Gainsborough’s imaginary landscapes at the Holburne in Bath, an ideal complement to the nine major Gainsborough portraits in their British picture gallery.

Surprisingly for one of the most prominent portrait-painters in all of British art, Gainsborough's animals, lovingly portrayed, their body language based on acute observation, dominate their human counterparts in these landscapes, who are more or less rural stereotypes.

John Martin is heaven. Well, as many of his contemporaries would have pointed out, John Martin is also hell, or The Last Judgement, or, as the Tate’s show title would have it, the Apocalypse at the very least. For John Martin was, after Turner, the 19th century’s premier painter of catastrophe. Unlike Turner, however, he was not much rated by the more respected critics, and his work, frequently oversized, tends to spend more time in storage than on the walls of public galleries.

Half of Wales is visible from the blustery summit. “Of all the hills which I saw in Wales,” recalled George Borrow, author of the prolix Victorian classic Wild Wales, “none made a greater impression upon me.” He was not alone. Arenig Fawr, a southern outcrop of Snowdonia, was also the entry point for British art into Post-Impressionism. This at any rate was the claim of a scenic documentary which joined Augustus John and his young protégé James Dickson Innes on their productive two-year sojourn at the foot of the mountain.
