You can use a computer to draw, as Hockney does, every day on his iPad, yet, despite all the technological advances the 21^st century has thrown our way, the pencil continues to be the artist’s most basic tool. And though there are those who lament, as they have done for decades, the “deskilling” of art, dismissing the art they don’t like or perhaps feel alienated by, drawing not only persists but remains fundamental: just as writers still write novels with plots to recreate the world filtered through their imaginations, artists still put pencil to paper to do the same.

London is by now festooned with images showing the back-end of a horse surmounted by a black figure holding a gun across his chest. The man's head is a square black mask – a rectangular slit in it fails to reveal the expected eyes, instead taking us straight through to the clouds and sky. Sid Nolan was creating an iconic image, especially for his fellow Irish-Australians, which would go on to become shorthand for the rebel, the larrikin spirit of the Aussie outfacing both the land-owning squattocracy and the land, which stretches out, deserted into the flat and boring distance.

There’s never a good day for traffic in the Hamptons, and a Friday in August takes the biscuit. The Montauk Highway, also known as Route 27, was bumper to bumper on the way to the Parrish Art Museum, recently relocated from nearby Southampton village to an exciting new building in the Watermill area. However the slow pace didn’t prevent me missing the turning for the museum, a remarkable achievement as it’s a vast barn-like structure, the length of two football fields, just off the highway on a site of a former tree nursery.

What happens when art is everywhere? Does it become wallpaper? Visual white noise?

The capital of Mozambique pulls no punches. Parked at the old airport among sheaves of wild grass are old MiG fighter planes, as sculpturally beautiful as the massive monument made from decommissioned weapons a few hundred metres away. The new airport, a multi-million pound effort completed last year with significant Chinese help, has Dom Perignon champagne for $230 a bottle. That’s twice the national annual wage. 

I’m watching someone with a mic pacing the linking bridge on the second floor of the Arndale Shopping Centre. He’s repeating the same phrase over and over again, which he’ll do for the next 20 or so minutes. “We’re souls refreshed,” I think it is. Nearby, sitting cross-legged, Lotus fashion, is a girl who, like the man with the mic, is wearing white cotton gloves.  In front of her are three stones, painted white, on a white handkerchief, and two hymnals. These props play a small part in the action, such as it is.

Ny Carlsberg Glyptotek is famous for its collection of antiquities: Egyptian carvings, Greek statues and Roman sculpture form the heart of its collection. Indeed, its collection of Roman portrait busts are among the finest in the world. But the 19^th century also has a strong sculptural presence. The double-bust of the founder of the museum Carl Jacobsen and his by then dead wife, Otillia – her ghostly arm placed protectively on his shoulder as she hovers behind him – might well be the most disconcerting.

I can’t wait to check out Istanbul’s galleries in a couple of years. Already endowed with an exploding arts and design scene, with Istanbul Modern in its unique location hanging over the Bosphorus, the retrospectively-looking Santral half integrated into an Ottoman power plant, and the area around Tophane sprouting art boutiques and design outlets like nobody’s business, its creative output has just been given a huge boost.

The Ghetto Heroes Square in the Muranow district of Warsaw is a bleak place surrounded by drab apartment blocks. But at its centre there’s now a new building that attracted over 15,000 visitors in the first two days of its opening on 20 and 21 April, the 70th anniversary of the Warsaw Ghetto Uprising of 1943. It’s particularly remarkable as the building doesn’t yet have any exhibits on show.

The work of Alphons Mucha (1860-1939) is immediately identifiable with its decorative flowers, delicate colours and wide-eyed women staring seductively at the viewer. He was one of the pioneers of art nouveau and the art of advertising. In Prague an exhibition recently opened which is packing them in at the glorious art nouveau Obecni Dům (Municipal House) in the centre of the city.
