Prehistory – human life before written language - enters art’s mainstream with this seminal and eye-opening exhibition. This one-off show, amplified by excellent labelling and atmospheric lighting, is enormously ambitious:  the largest anthology of portable prehistoric European art there has ever been, unprecedented in its scope with artefacts from museums in Russia, Germany, France, and the Czech Republic, homes to the greatest of the sites.

Carving in Britain from 1910 to Now is an accurate but unalluring title for what is a seminal show. The Fine Art Society is one of the oldest commercial galleries in Britain, founded in 1876 and still in its original building. Due to this longevity the FAS has unusual access to private collections, and an ability to mix the historic and contemporary to fine effect. The result here showcases an original anthology, simultaneously scholarly and commercial, a mix of loans and for-sale.

Imagine that Rodin’s Thinker gets bored with sitting, head-on-hand, contemplating the folly of humankind and, springing to life, descends from his lofty perch above The Gates of Hell. Having been immobile for a century or more, he is extremely stiff and needs to limber up: cue for some first-rate body popping interspersed with the kind of heroic poses usually reserved for life drawing classes. 

A Dancing Satyr leaps into the air, his head thrown back in ecstasy. His alabaster eyes appear like two pinpoints of illumination in the dimly lit gallery. The bronze figure, which is the first work you encounter in an exhibition spanning 5,000 years of bronze sculpture, is believed to be the work of the famous Greek sculptor Praxiteles, who was active in the second half of the fourth century BC.

There is a growing fashion for new public sculpture and anthologies of contemporary sculpture outdoors, inspiring various polemics for and against. Kew Gardens has been at it for nearly a decade: there was a triumphant Henry Moore show several years ago, followed by glass artist Dale Chihuly festooning their lakes and ponds. The current artist-in-residence, David Nash, creates works with wood from fallen trees.

What a mismatch of ambitions was unearthed in this Culture Show special on the ArcelorMittal Orbit. Boris Johnson admitted that he’d wanted slides on it, joking heartily that “there’s nothing too vulgar for me”, whilst Anish Kapoor wished for it to be “up there with the gods”, and mused that it had moments that were meditative and contemplative. Meanwhile, the artist expressed sheer horror that the Olympic Authorities where keen to call it “an attraction”, despite the public’s insistence on calling it a helter-skelter.

There’s a lot of art currently happening under the wing of the London 2012 Cultural Olympiad. The common denominator, if there is one, is showstopping ambition and the concept of the inclusive spectacle. What there isn’t much of, whisper it softly, is art inspired by sport.

Yesterday I fell in love with a black boy less than half my age and half my size – or, rather, a sculpture of a black boy. At just over two feet tall, Ron Mueck’s Youth is utterly beguiling. His silken skin, slender fingers, low-slung jeans and paisley patterned underpants are seductive enough; what made me lose my head, though, was the suggestion of dirt under his neatly clipped toenails. This beautifully observed detail made me want to kiss his exquisitely modelled feet.

On the tip-off of an art-loving West Country amigo, Miss April and I took a day out of our Easter hols to visit the recently re-opened Royal Albert Memorial Museum & Art Gallery, in Exeter.

The first and most unusual aspect of Caro at Chatsworth is that it is there: 15 outstanding sculptures by Sir Anthony Caro, placed in an irregular pattern around the formal 950ft early-18th-century Canal Pond, situated facing the southern vista of the great Baroque house. For these sculptures are tough, the antithesis of any sentimental attachment to a rural Arcadia, almost relentlessly urban and even architectural. Caro once used the term "archisculpture" for his ambitious work.
