Artist George Stubbs liked horses. The MK Gallery’s exhibition “all done from Nature” will try to convince you that he also cared about people. He did, to an extent; the commissions came that way. But about half way through the exhibition, the diminutive Study for Three Hunters and Two Grooms Waiting in a Stable-Yard, 1765-70, gives pause for thought. The detailed study depicts a horse with pensive eyes and toned flanks.

Lucian Freud died in 2011 after a career spanning some 70 odd years. Over the decades, he painted and drew himself repeatedly, creating a fascinating portrait of a man who spent an inordinate amount of time scrutinising himself and others.

“People collect diamonds because they sparkle; or they sit on a bench in Cornwall and look out to sea”. At the Hayward Gallery for the opening of her retrospective, Bridget Riley speaks of such uncomplicated pleasures with evident delight.

Focusing on twelve women who played a key role in the lives of Pre-Raphaelite painters like Dante Gabriel Rossetti, John Everett Millais and William Holman Hunt, this timely exhibition begins with a whimper and ends with a bang. First up at the National Portrait Gallery is Effie Gray whose marriage to art critic, John Ruskin was annulled after six years for non-consummation. The story goes that, having only seen classical Greek sculptures, he was horrified by her pubic hair!

Among the numerous exhibitions marking the 350^th anniversary of Rembrandt’s death, this small show at the Dulwich Picture Gallery stands out.

Now in her mid-seventies, Anna Maria Maiolino has been making work for six decades. Its a long stretch to cover in an exhibition, especially when the artist is not well known. Perhaps inevitably, then, this Whitechapel Gallery retrospective seems somewhat sketchy and opaque, a feeling compounded by having titles in Portuguese. The work is so interesting and so diverse, though, that engaging with it is well worth the effort.

“Gauguin was undoubtedly self-obsessed” begins the National Gallery’s latest dead cert blockbuster, as it cheerfully hijacks a de facto series begun next door at the National Portrait Gallery.

The Barbican’s latest offering – a look at the clubs and cabarets set up by artists mainly in the early years of the 20th century – is a brilliant theme for an exhibition.
