Exhibition of the week Christina Quarles: In Likeness Paintings of furiously entwined, fragmentary, fluid bodies by this hot American artist. South London Gallery until 29 August Also showing Helen Frankenthaler: Imagining Landscapes Sensual yet authoritative masterpieces by one of the greatest abstract expressionist painters, beautifully presented in a show that’s like a trip to New York. Read my five-star review here. Gagosian Grosvenor Hill, London, until 27 August Gustave Moreau: The Fables Illustrations of animal fables by this marvellously decadent French genius, who is overdue a big exhibition in Britain. Waddesdon Manor, Aylesbury until 17 October Barbara Hepworth: Art and Life A survey of the pioneering Yorkshire-born sculptor who sought a secret music in nature. The Hepworth, Wakefield until 27 February Yorkshire Sculpture International As the birthplace of Hepworth and Henry Moore, Yorkshire can claim a special relationship with sculpture, and makes that claim here with shows across several spaces by local and global talents, including Akeelah Bertram and Ashley Holmes. At various venues in Yorkshire until September Image of the week Antony Gormley says he hopes his “iron men” on a Merseyside beach will still exist in at least 1,000 years as “industrial fossils”, after helping to excavate 10 that had been subsumed by Irish Sea mud. One hundred cast-iron statues modelled on Gormley were installed in 2005 at Crosby beach, spread across 3km of the foreshore and stretching almost 1km out to sea. The installation, Another Place, was only supposed to last 16 months in Crosby, and the men were almost sent packing early amid safety complaints, including cases of the coastguard being called out to “rescue” them. Sixteen years on, the artwork has become a tourist attraction and a beloved local institution. Read the full story here.

The comparison is instructive. Both are provocative and funny. This painting’s moralising title and the symbolism attributed to it – contrasting, we are told, wise chaste love with carnal sin – have almost nothing to do with the experience of looking at it. Either Renaissance courtiers were incredibly hypocritical, enjoying this scene of an unbuttoned picnic while pretending to tut, or they were in on a game in which the real meat was, and is, a Rabelaisian delight in the sensual.
