Feelings run high at the Hayward Gallery in a fascinating pairing of two artists from widely differing backgrounds. Kader Attia muses on unhappy, conflicted relationships between cultures in visual meditations on variations of colonialism. Diane Arbus, who died at the age Attia is now, photographed people who were often at the margins of society.

Pink walls, slightly dusky in the subdued light of a room shielded from the wintry sun, suggest the bodily concerns of this show, which through the touring collection Artists' Rooms, boldly reviews Louise Bourgeois’s career in a single, modestly sized, exhibition space at Kettle’s Yard. For a prolific artist associated with large-scale sculptures, the most obvious question is “How?”.

Tate Modern’s retrospective of Dorothea Tanning is a revelation. Here the American artist is known as a latter day Surrealist, but as the show demonstrates, this is only part of the story. Tanning’s career spanned an impressive 70 years – she died in 2012 aged 101 – but as so often happens, she was eclipsed by her famous husband, German Surrealist Max Ernst. 

Franz West must have been a right pain in the arse. He left school at 16, went travelling, got hooked on hard drugs which he later replaced with heavy drinking, got into endless arguments and fights, was obsessed with sex and, above all, wanted to be an artist but hadn’t been to art school. His life reads like a bad novel or Hollywood’s idea of the tortured genius struggling to make his mark in a world indifferent to his talents.

It doesn’t get better than this! Phyllida Barlow has transformed the Royal Academy’s Gabrielle Jungels-Winkler Galleries into a euphoric delight. Entering the space, you have to turn right and process through the three galleries; but by closing the end door to create the cul-de-sac of the title, Barlow has turned this somewhat prescriptive lay-out into a theatrical experience.

The power of seeing was the bedrock of John Ruskin’s philosophy. In the bicentenary of his birth, a revelatory exhibition at Two Temple Place in London opens out the idea and makes it manifest through both his own work and the treasures of his collection.

I interviewed Don McCullin in 1983 and the encounter felt like peering into a deep well of darkness. The previous year he’d been in Beirut photographing the atrocities carried out by people on both sides of the civil war and his impeccably composed pictures were being published as a book. 

“Slow looking” is the phrase du jour at Tate Modern, an enjoinder flatly contradicted by the extent of this exhibition, which in the history of the gallery’s supersized shows counts as a blow-out.

The heart of the V&A’s sumptuous Christian Dior: Designer of Dreams is a room dedicated to the workmanship of the fashion house’s ateliers. A mirrored ceiling reflects dazzling strip-lit cases which hold the ghosts of ballgowns, slips and jackets — adjusted prototypes, haute couture maquettes — made in white toile by the seamstresses of Dior’s Paris studios before they begin work on the final garment.

For an artist whose cerebral and frequently playful works reference physics, myth and music, Fausto Melotti’s artistic education was appropriately heterogeneous.
