This week's art exhibitions offer a diverse range of themes, from the surreal to the environmental, and from historical painting to contemporary installations. At Gagosian Grosvenor Hill in London, the exhibition "This Is Still Not a Pipe: The Afterlife of Magritte" explores the work of Belgian surrealist René Magritte. The show includes loans of his original paintings, as well as contemporary works by artists like Sarah Lucas and Matthew Barney, who reinterpret Magritte’s themes of reality and illusion. The exhibition runs from 24 September until 12 December. Also in London, the Wallace Collection is showcasing "Rachel Kneebone – Metamorphoses: Porcelain Sculpture" from 23 September until 25 April. This exhibition features intricate porcelain sculptures that rework the ornate designs of the Rococo period, blending historical aesthetics with modern artistic expression. Meanwhile, the Eden Project in Bodelva is hosting "Extinction: Renewal, Art of a Living Planet," an exhibition that runs until 19 September 2027. Featuring works by artists such as David Nash and Cristina Mittermeier, the show addresses the challenges facing the natural world, including biodiversity loss and climate change. In London's Serpentine North Gallery, the exhibition "Amar Kanwar" presents films and video installations that explore the modern history of India, Pakistan, and Bangladesh. Running from 23 September until 31 January, the show offers a critical and often poetic reflection on the political and cultural landscapes of South Asia. At White Cube Bermondsey, the retrospective "Gabriel Orozco: Chronotopic" runs until 8 November. Known for his conceptual approach, Orozco’s work includes the famous reworking of a Citroën DS, where he cut open the car and reassembled it in a new form. A new installation by Bristol artist Luke Jerram, offering a bee's-eye view of the world, is set to appear along the Thames in east London. The piece, which looks like a grain of pollen on the outside and features an insect's compound eye on the inside, aims to highlight the decline in pollinator populations, which have dropped by 60% in the last 20 years. Finally, at the National Gallery, "Two Men With a Sleeping Woman" by Gabriel Metsu, dated around 1655–60, offers a glimpse into 17th-century Dutch domestic life. The painting depicts a sleeping woman with a pipe in her hand, alongside various objects that suggest a scene of leisure and moral ambiguity.
