Alice Neel: Painted Truths, Whitechapel Gallery

Neel wanted to get under the skin of her sitters. Her unflinching gaze served her well

What a troubled life Alice Neel led. The death of her first child, a daughter, who died of diphtheria in 1928  just before her first birthday; another daughter lost to her estranged husband’s family in Cuba two years later (as an adult and a mother herself, the daughter, Isabetta, committed suicide); life as a single mother raising two later sons on welfare in the slum district of New York's Spanish Harlem; and a neglected but always diligent artist for much of the rest of it, only achieving fame and acclaim towards the end.

Tim Marlow Meets Terry Jones, Sky Arts

The former Python and medieval scholar chats about his favourite paintings

He may be a writer, a director, an actor, a historian, and, of course, a former member of Monty Python, yet rather than being a Renaissance man, Terry Jones is clearly a mediaevalist at heart. We know this not only because he has written well-received books on Chaucer and medieval history, but an amiable half hour spent in his company at the National Gallery shows us just where his sensibilities lie. He was the first guest in a series inviting celebs to talk about their favourite artworks and Tim Marlow, whose televisual style is so effortlessly smooth and mellow that you might mistake him for a brand of instant (decaff) coffee were it not for his serious, but never heavily worn erudition, proved to be the perfect host: unlike more excitable presenters in the genre of television arts, he never upstages his guests.

Close Examination: Fakes, Mistakes and Discoveries, National Gallery

A genuine Rembrandt or a fake? The painting detectives lay out the secrets of their trade

When is a fake a forgery? When is it a mistake? And when is it simply not what it appears? The National Gallery’s second summer exhibition to focus on its own collection here examines the questions of attribution, using the latest scientific resources to back up – or contradict – tradition, connoisseurship and curatorial decisions, good and bad. The gallery is putting its own mistakes on show, and over the 170-plus years of its existence, there have been more than a few.

BP Portrait Award 2010, National Portrait Gallery

What are portraits for? You might find the answer right here

Last month, the National Portrait Gallery unveiled a huge, new portrait of Anna Wintour. Painted by Alex Katz, the celebrated New York Pop portraitist, American Vogue’s scary editor-in-chief is shown with famous helmet bob intact, but minus her trademark dark glasses. The picture depicts Wintour, whose icy blue stare could run a chill through you (she's known as Nuclear Wintour), against a sunny yellow backdrop –  which looks like an attempt to raise the temperature of that icicle glare. You pass it as you enter this year’s BP Portrait Award.

Art Gallery: Terry Setch - Lavernock

Sumptuous paintings of the post-industrial Welsh coastline from an underrated master

Terry Setch can lay claim to being the most underrated artist in Britain. Not that the Cardiff-based Londoner has been entirely neglected: acclaimed as one of Britain’s most powerful painters by his contemporary John Hoyland, he’s been garlanded with awards, granted a retrospective at The Serpentine and was recently made an RA. Yet Setch (born 1936) has still had nothing like the recognition he deserves as one of Britain’s most intelligent and inventive painters. And the crime for which he’s been sentenced to this relative obscurity: simply, not being based in London, but in Wales.

Art Gallery: Howard Hodgkin - Time and Place

Enter the colour-saturated world of an artist often compared to Matisse

Howard Hodgkin is unquestionably the grand figure of British non-figurative painting. Often compared to Matisse in his use of intense colour, he has always insisted that his paintings are not abstract. They allude, he says, to memories of people and places and states of being, so that his titles are what you would expect from a landscape artist or even, occasionally, a chronicler of modern manners: Dirty Weather, Spring Rain, Privacy and Self Expression in the Bedroom. And he often paints on unconventional surfaces, favouring wood rather than canvas, painting the frame so that we see the paintings more as objects than as two-dimensional surfaces. Tate Britain’s major 2006 retrospective surveyed his work over six decades, but a new exhibition, at Modern Art Oxford, is a tightly focused affair: paintings executed by the 77-year-old artist over the last decade, including a body of new work. They offer a window on to a brilliant, colour-saturated world.

Doctor Who: Vincent and the Doctor, BBC One

The Doctor tries to rescue Van Gogh from his demons, real or imagined

The Doctor Who crew are fond of their encounters with historical characters. In his time, and let's face it he has infinite supplies of it, the Doc has rubbed shoulders with Shakespeare, Charles Dickens and Agatha Christie, and recently weathered the Blitz with Winston Churchill. For this one, "Vincent and the Doctor", le Docteur voyaged back to 19th-century Provence to straighten out a puzzling temporal kink.

Newspeak: British Art Now, Saatchi Gallery

It's a bit like the Royal Academy Summer Show trying to do 'edgy'

These days, it seems that approaching any new Saatchi exhibition, especially one that promises to be even bigger than all the previous ones held at the multi-galleried, three-storey Chelsea venue, makes the heart fairly sink. How much bigger, you want to ask, and why use size as a measure of anything?  Surely there isn’t enough headspace to accommodate all those loud, clamorous, “look-at-me” artworks favoured by Saatchi all in one go? And this is just Part One. Part Two will be something to look forward to in late October.

Picasso Special - Picasso: Peace and Freedom, Tate Liverpool

Picasso the feminist? A sweeping survey puts the artist's politics under the spotlight

Picasso the genius, the sensualist, the womaniser, the priapic beast. This much we think we know of the great Spanish artist. But how about Picasso the political activist? Picasso the supporter of women’s causes? Picasso the… feminist? Oh, yes, that Picasso. In a landmark Liverpool exhibition focusing on the years 1944 to his death in 1973, and bringing together 150 works from around the globe, Picasso becomes all of these things.

Art Gallery: Picasso Special - The Mediterranean Years

Picasso's Picassos - a portfolio of the works he kept for himself

The war was over, Picasso was finally free to leave the privations of Paris behind him and to spend more time in the South of France, marking a return to his Mediterranean heritage. The Gagosian Gallery’s exhibition, curated by Picasso’s distinguished biographer John Richardson and the artist’s grandson Bernard Ruiz-Picasso, focuses on those Mediterranean years, between 1945 to 1962, when the artist was moving easily between styles.
