This article examines the unusual history and legal status of the Tor de’ Specchi community, founded by Francesca Romana (d. 1440) in Rome, in the face of shifting expectations for religious women in Counter-Reformation Catholicism. It is argued that Francesca Romana had sought to carve out a religious path for women distinct from that of nuns as brides of Christ (‘sponsae Christi’). The article demonstrates the community's difficulties in maintaining this way of life in the face of Pope Pius V's 1566 bull Circa Pastoralis, which extended the Council of Trent's 1563 decrees on enclosure (clausura) to all nuns of every order.
