In a country house in Derbyshire in 1809, thirteen-year-old Thomasina Coverly decides to invent a new Geometry of Irregular Forms. Her mathematical discoveries are in advance of her time, but they match the transformations of Sidley Park, in which the Arcadian landscape of the 18th century is giving way to Romantic disorder. They also echo the irregular, unpredictable nature of sexual attraction which she observes around her, and the resulting sentimental imbroglio that Hannah Jarvis and Bernard Nightingale will attempt to unravel 180 years later. In the comical entanglements that ensue, art and science engage in a witty dramatic dialogue, and sex is always part of the equation.Tom Stoppard’sArcadiaplays with the traditional divisions between Classicism and Romanticism, art and science, order and disorder.
