Saint Calocerus (Italian: Caio, Calocero, Calogero) was a 2nd-century Christian martyr. His alleged "acts", belong to a much later period.
He was probably an officer in the Roman army under the Roman emperor Hadrian and was stationed in Brescia in Lombardy, Italy.[1] His life and legend are associated with Saints Faustinus and Jovita, and according to tradition, all three saints were soldiers from Brescia.[2] The constancy of Faustinus and Jovita led to the conversion of Calocerus, who in turn converted Secundus of Asti.[3]
According to tradition, Calocerus preached at Albenga and was martyred in this town.[2]
A local cult devoted to Calocerus was limited to the dioceses of Brescia, Milan, Asti, Ivrea and Tortona.[2] The cathedral of Albenga, built in the fourth and fifth centuries, was dedicated to him.[2] The alleged tomb of Saint Calocerus is conserved in the Civic Museum at Albenga.[2] The cathedral of Albenga contains an urn with some of his relics.[2]
