Caucasian Chalk Circle, a play originally by Bertolt Brecht, is the story of Grusha, a peasant, forced to flee a Caucasian city as a result of a revolt. She saves the abandoned child of the city’s governor who has been killed and develops strong maternal instincts towards the baby. She crosses dangerous hurdles and makes several sacrifices for the sake of this child.
After two years, a counter-revolt returns the governor’s party to power. The governor’s widow can only stake claim on his estate as the mother of his legal heir. Grusha and the infant are thus tracked and brought by soldiers to trial before the city judge, Azdak, who uses something called the ‘chalk circle’ to judge the identity of the “real” mother.
