Chiara Margarita Cozzolani

Chiara Margarita Cozzolani (27 November 1602 – ca. 1676–1678), was a Baroque music composer, singer and Benedictine nun. She spent her adult life cloistered in the convent of Santa Radegonda, Milan, where she served as prioress and abbess and stopped composing. She was one of more than a dozen cloistered women who published sacred music in seventeenth-century Italy.
