These days, the city of Milan is hosting Metafisica/Metafisiche, a wide-ranging exhibition on the concept of metaphysical art developed by the Italian painter Giorgio De Chirico. Not many exhibitions make you question how you read a room. This one does. Curated by Vincenzo Trione, the show gathers around 400 works – paintings, sculptures, photographs, design objects, architectural models, videos and more – loaned by over 150 institutions from across the world.
