Dominic Loricatus was an Italian Benedictine monk and abbot who lived from approximately 995 to 1060. Originally ordained as a secular priest through simony, he later entered monastic life to seek atonement for his early sins. He became a devoted follower of Peter Damian, seeking even more rigorous ascetic practices at the Fonte-Avellana hermitage. He is famously recognized for his extreme penitential habits, which included wearing a protective mail shirt and performing intense acts of self-flagellation to atone for his transgressions.
