EUSTORGIUS (Saint) Bishop (September 18) (4th century) A Greek, traditionally held to have been an official in the service of the Emperor Constantine the Great. He was elected Bishop of Milan in succession to Saint Maternus, or possibly Saint Mirocles. He appears from a letter of Saint Athanasius to have suffered for the Faith, and to have written in defense of orthodoxy against the Arians. To him is attributed the acquisition for Milan of the relics of the Three Magi, afterwards by Frederic Barbarossa transported to Cologne. He held the See of Milan from A.D. 315 to A.D. 331.
