Hyacintha Mariscotti was a 17th-century Italian nun of the Franciscan Third Order Regular. Born into a noble family in Vignanello in 1585, she initially struggled to reconcile her religious vows with a desire for worldly comforts. After a period of living in contradiction to her monastic commitments, she underwent a profound spiritual transformation. She dedicated the remainder of her life to asceticism and service, eventually gaining a reputation for immense holiness before her death in Viterbo in 1640.
