Caryl Churchill’s Light Shining in Buckinghamshire, first performed in 1976, is a dense and difficult play set during the English Civil War. The period may be distant in time but Churchill, working in a broadly Marxist tradition, sees it as an era when fundamental questions of governance were tested by a mass of ordinary people. From whom does the state derive authority, and is a person bound to obey laws they find unjust? Does the existence of private property – those enclosed lands cultivated for the profit of a few – offend against the common good? Do the rich offend God? ‘For a short time when the king had been defeated anything seemed possible,’ Churchill wrote in a 1978 introductory note. The possibilities included, for some, Christ’s return and with it the instigation of an earthly Paradise.
