Chairs, chairs, chairs, as far as the eye can see. Plywood or plastic shells, some decorated with hilarious drawings of jolly nudes by Saul Steinberg (main picture), others in all the colours you can imagine – stacks, in rows, alluring and all so familiar. As it is an exhibition, there is an air of reverence – heaven forbid that you actually have a chair to sit on! - but these chairs have been design icons for well over half a century.

Belgian filmmaker Chantal Akerman used her camera to record, with a sympathetic eye, the world around her – both in the immediate surroundings of her Paris flat and in the wider world. The news that she died last month, apparently by her own hand, sadly makes this retrospective of the installations she began creating in 1995 all the more timely.

Metal figures on the foreshore of Crosby Beach, Liverpool, set against a sunset, signify the preoccupations of Antony Gormley. The sculptor has been concerned consistently with the human figure, manifested in metal – lead or iron – casts of his own body.

Switching between the orderly and the chaotic, David Jones’ depiction of Noah’s family building the ark immerses us in the drama of the moment while simultaneously holding us at some point out of time, to emphasise the story’s ancient roots.

Poetry is everywhere in Mons, with 10 kilometres of verse painted along the city streets. You’ll even find it on the walls of the city’s imposing 19th-century prison, at odds with the arrow slits, the crenellations, and the towering nets preventing family or friends throwing contraband into the exercise yards.

Sometimes it’s visual art with a sonic slant; sometimes it’s music with a visual slant. Glasgow’s Sonica – created by producers Cryptic, now in its third year and bigger than ever – feels like a thoroughly modern festival, defying genre boundaries and instead focusing squarely on the intersection of the sonic and the visual. That might make some of its offerings hard to categorise, but there’s nothing wrong with that.

Any exhibition of Sol LeWitt’s work raises an interesting question. Why go and see it if it’s the idea that’s the most important aspect of the work? In his 1967 essay, “Paragraphs on Conceptual Art”, he clearly outlined the predominance of the idea over material form, which may seem an obvious statement to make about conceptual art (the label’s on the tin) but LeWitt went further. “All of the planning and decisions are made beforehand and the execution is a perfunctory affair,” he wrote. “The idea becomes a machine that makes the art.”

This was the fifth and last in a series of hour-long programmes amounting to a vivid, varied and extraordinarily lively history of Britain. Although ostensibly a history of portraiture, the images have been hooks for Simon Schama, that most ubiquitous historian who bears a rather charming resemblance to Tigger – very bouncy, very chatty, very enthusiastic, a little self-regarding – to subtly engage us in a journey through the political and social landmarks of British history.

Unswervingly confident, relaxed and assured, the élite of the 18^th century are currently arrayed on the walls of the Royal Academy, gazing down at us with the utmost assurance of their unassailable place in the world, bright eyed and dressed to match. The swirls of public reputation are unpredictable: here is a revelation, the art of one of the most successful and highly prized portraitists of his day, Jean-Etienne Liotard (1702-1789), now almost completely unknown except to specialists.

What a woman. Does the news that Kate Winslet is to play the polymath Lee Miller in a Hollywood biopic mean a kind of sanctified apotheosis of Miller's quite extraordinary life? The story is so dramatic it transcends any fiction. Her path was controversial, imaginative, accomplished, and in many ways profoundly sad, an emotional roller-coaster. But the legacy is astonishing, as more and more of her achievement as a photographer is revealed.
