Peter Konwitschny’s new production of Cosi Fan Tutte examines sex as an eruptive force of nature that needs to be accepted as such if we are ever to live with it. “I seem to have Vesuvius in my breast,” Dorabella sings, as her growing desire for Guglielmo sweeps thoughts of Ferrando from her mind. Nature, of which she is a part, convulses appropriately with her words: she and Guglielmo snaffle round each other like animals, as steam hisses through the floor and lava trickles round their feet.
