Columba of Rieti was a 15th-century Italian Dominican tertiary and mystic born in Rieti. Known for her intense spiritual devotion and frequent ecstasies, she dedicated her life to prayer and service to the poor. After fleeing an arranged marriage by cutting her hair, she eventually moved to Perugia, where she served as a prioress for eleven years. Her extreme fasting and ascetic practices, which were viewed as signs of piety during her era, eventually led to her death at the age of 34.
