The old observatory on Edinburgh’s Calton Hill may be the most favourably positioned art venue in the world. Recently resurrected by a group called Collective, the space, with its panoramic views and Enlightenment history, is an ambitious and imaginative addition to Edinburgh’s art scene. In their Hillside gallery there’s a firing-range warning sign on the screen, a few seconds of stillness and silence, then a sudden machine-gun rattle. The sound is revealed to be a stick, dragged by a child along corrugated iron, and the juxtaposition is the strongest moment in Helen McCrorie’s portentously titled video work, ‘If play is neither inside nor outside, where is it?’ (until 6 October).

Bunnies were out. Beatrix Potter had the monopoly on rabbits, kittens, ducks and Mrs Tittlemouses. ‘I knew I had to bring in creatures of some kind,’ wrote Roald Dahl on his first thoughts towards a children’s book. ‘But I didn’t want to use all the old favourites that had been used so often before, like bunnies and squirrels and hedgehogs. I wanted new creatures that no one else had ever used.’ After making a long list of earwigs, pond skaters and Devil’s coach-horse beetles, Dahl cast a centipede, an earthworm, a silkworm, a glow-worm, a spider, a ladybird and an old-green-grasshopper. ‘It was fun,’ the author wrote, ‘to sit down

Steel flowers bend in a ‘breeze’ generated by magnetic pendulums. This is the first thing you see as you enter Tate Modern’s survey show. And ‘Magnetic Fields’ (1969) is pretty enough: the work of this self-taught artist, now in his nineties, has rarely been so gentle, or so intuitive. But there’s a problem. ‘I would like to render [electromagnetism] visible so as to communicate its existence and make its importance known,’ Takis has written. But magnetism hides in plain sight. A certain amount of interference is necessary before it will reveal itself. Does the interference matter? Does the fact that gallery assistants have to activate this work every ten minutes

The art-history books will tell you that sometime around 1912, Picasso invented collage, or, actually, perhaps it was Braque. What they mean is that sometime around 1912 a man of sufficient standing took up a technique that had been quietly practised in largely domestic spheres by a largely female army of amateurs, and applied it in his own work. Cue the universal astonishment of observers who pretended they had never seen such a thing before. This narrative has been recycled ever since, assuring us that the collage techniques that shaped the language of dada, surrealism and all the other isms that made up modernism, as well as pop art and

The selfie is, of course, a major, and to me mysterious, phenomenon of our age. The sheer indefatigability of selfie-takers, not to mention their number, is amazing. Recently, I stayed in an apartment not far from the Trevi Fountain in Rome — a selfie-magnet so powerful that not only was it surrounded by a dense crowd during daylight hours, but a small, determined knot could still be spotted late at night, doggedly snapping away in the dark under a steady drizzle. This global fixation adds an extra interest to the retrospective of work by Cindy Sherman at the National Portrait Gallery. She has been making pictures of herself, and little

In 1965 a journalist asked Paula Rego why she painted. ‘To give a face to fear,’ she replied (those were the days of the Salazar dictatorship in Portugal). But when asked the same question shortly afterwards, Rego added a qualification: ‘There’s more to it than that: I paint because I can’t stop painting.’ Rego has carried on making pictures ever since and the results can be seen in a remarkable exhibition, Obedience and Defiance, curated by Catherine Lampert at the MK Gallery, Milton Keynes. This is not quite a career retrospective — Rego will get one of those at Tate Britain in 2021. But it is the first time that

‘It is no easier to make a good painting,’ wrote Vincent van Gogh to his brother Theo, than it is ‘to find a diamond or a pearl.’ He was quite correct. Truly marvellous pictures are extremely rare. To make one, Vincent went on, you have to ‘stake your life’ (as he, indeed, was doing). Well, there is just such a jewel of a painting — only one by my count — in Francis Bacon: Couplings, an exhibition at Gagosian, 20 Grosvenor Hill. In some cases, the title of the show is literal. Several pictures depict two naked men in a ferocious sexual tangle. As a subject, this is perhaps still

‘The possibilities of paint,’ Frank Bowling has observed, ‘are endless.’ The superb career retrospective of his work at Tate Britain demonstrates as no words could that he is correct, and that the obituaries of this perennial medium — so often declared moribund or defunct — are completely wrong. This presents more than half a century’s virtuoso exploration of what pigment on canvas can achieve. After his first decade of work, Bowling (born 1934) became what is called an abstract artist. But that is a vague and unsatisfactory category. His early, figurative pictures such as ‘Cover Girl’ (1966) could be labelled ‘pop’. It features an image of a Japanese supermodel garnered

Plastics — even venerable, historically eloquent plastics — hardly draw the eye. As this show’s insightful accompanying publication (a snip at £3) would have it, ‘Plastics have no intrinsic form or texture, thus they are not materials that can be true to themselves.’ They exist within inverted commas. They can be shell-like, horn-like, stony, metallic — they do not really exist on their own behalf. Mind you, the first vitrine in Raw Materials: Plastics at the Nunnery Gallery in east London contains an object of rare beauty: a small, mottled, crazed, discoloured sphere that looks for all the world like the planet Venus, reduced to handy scale. It’s a billiard

Henry Moore was, it seems, one of the most notable fresh-air fiends in art history. Not only did he prefer to carve stone outside — working in his studio felt like being in ‘prison’ — but he felt the sculpture came out better that way too, in natural light. What’s more, he believed that the finished works looked at their best in the open air. This last idea is tested in a new exhibition, Henry Moore at Houghton Hall: Nature and Inspiration — and it turns out that the artist was absolutely right. This — the latest in an enterprising series of shows at this north Norfolk mansion — is
