Domninus of Fidenza was a third-century Christian martyr from the Parma region of Italy. According to tradition, he served as a chamberlain and keeper of the royal crown for Emperor Maximian. After converting to Christianity, he faced the wrath of the emperor and was pursued by imperial soldiers. He was eventually caught and beheaded near the Stirone river, outside of Fidenza, in 304 AD.
Life and martyrdom


Legendary accounts suggest that while fleeing imperial forces, Domninus rode through Piacenza carrying a cross. Following his execution, he reportedly picked up his own severed head and carried it to the location where the cathedral in Fidenza would eventually be built. His life and death are recorded in the Hieronymian Martyrology, though other historical martyrologies do not mention him.
Veneration and legacy

His remains are kept in the cathedral of Fidenza, a town formerly known as Borgo San Donnino. The site features a sculpted frieze depicting his life, attributed to the school of Benedetto Antelami. Historically, he was a popular figure in Northern Italy and was invoked as a protector against rabies. In religious art, he is often shown in military clothing holding a palm.
