Juana de la Cruz (1481–1534) is a unique figure in the history of the Catholic Church, thanks to her public visionary experiences during which she lost consciousness, while a deep voice, identifying itself as Christ, issued from her, narrating the feasts and pageants taking place in heaven. Juana’s so called “sermons,” collected in a manuscript called Libro del Conorte, form a fascinating window into Castilian religiosity in the early sixteenth century. There is much to reap from these sermons concerning Spanish Renaissance culture, theology, mysticism, gender roles, and interreligious interactions.
