This image may share the unpretentious quiddity of Giorgio Morandi’s bottle paintings and the prismatic lucidity of Rodric O’Conor’s, but it is not an everyday still life. At the Venice Biennale, Lotus L Kang arranged 49 bottles of spirits in front of film reels of tidal mudflats and visualisations of birdsong, to reflect the Buddhist belief that a soul spends 49 days between death and rebirth. The images are now part of Kang’s shortlisted entry for the prestigious Deutsche Börse photography prize.

Autumn Evening by Henri-Joseph Harpignies, 1894

This painting is a reminder that art isn’t really a progression from old to new, a wave of movements displacing the past, but a great big fascinating mess, with artists at any one time working in many styles, including archaic ones. For this calming, eerily beautiful view of rusty-leaved birches against a bronzed evening sky was painted in the 1890s when Cézanne, Munch and Toulouse-Lautrec were building modernism – but Harpignies has absolutely no interest in that. This painting is not even touched by impressionism, which had started in the 1870s. Instead it is completely loyal to the artistic ideas of the painter’s youth. Born in 1819, Harpignies was a diehard classicist steeped in the light of Italy that he saw on his travels. This landscape has the same charm as finding a totally archaic bistro in a remote French village and eating its coq au vin as the sun goes down. National Gallery, London
