Image of the week Going Home by Benji Reid This image is from Reid’s first solo exhibition, Laugh at Gravity, part of Photo London 2021. Reid considers himself a Choreo-Photolist, a term he coined to encapsulate his practice where theatricality, choreography and photography meet in the image. In the hyperrealities he presents, the subject is liberated by acts of the artist’s imagination.

In the second half of the 18th-century, neoclassicism, partly inspired by the excavation of Pompeii, took a more serious and archaeological approach. But Fragonard couldn’t care less. For him, the tale of Cupid and Psyche is just an excuse to paint frills and flesh. This decadent artist of the ancien regime delights in silky layers of colour. As you look at this picture for a while its narrative details seem to melt. All that is left is a heady perfume of amorous languor. National Gallery, London.
